In the previous blog, we focused on tips to prolong the life of your compressed air accessories. Today we will discuss the importance of establishing an inspection routine for your entire compressed air system along with a checklist of items to inspect.

 

Benefits of Regular Inspections

There are significant returns on the time you spend to inspect your compressed air system regularly. It just takes a little organization to collect detailed information and track changes. This data will encourage and direct your team to perform preventable actions to enhance your compressed air system’s performance. Other benefits of routine inspection include boosting productivity, decreasing waste, optimizing efficiency, seeing opportunities for compressed air applications, and planning for the future. This priceless information regarding efficiency and production, collected just by identifying leaks or areas of potential leaks will allow Nex Flow to recommend cost savings and increased reliability of equipment. It may also encourage your team to simply clean accessories, such as filters regularly.  The knowledge of  the acceptable working range of the gauges will ensure your system is running well. This knowledge can prevent major damage to equipment and prevent costly repair. It will also prolong the life of your equipment.  Simply put, regular inspections will allow your compressed air system to go further, do more, and be more valuable.

 

Before the Inspection

It is handy to record the equipment data on a tracking sheet before you begin your inspection.  Search through your files and write down the type of compressor, and manufacturer, the model and serial numbers, and flow rating Cubic Feet per Minute (CFM).  Other useful compressor information includes the horsepower at revolutions per minute (HP@RPM) and pressure rating pounds per square inch gauge (PSIG). Determine if the compressor is equipped with a pressure gauge or spring-loaded safety valve. Some compressors have a drain valve while others allow you to remove water and oil.

Know the dryer manufacturer, exit flow rate at the dew point (oC or oF), and model and serial numbers. Record the oil/water separator manufacturer, model and serial numbers, and the flow rate in CFM. Keep these inspection sheets in a binder and refer to them often.

 

Inspection Equipment

To make easy your inspection, Nex Flow offers leak detecting equipment that makes your routine checks effortless. Ultrasonic leak detectors identify issues before they become costly to repair. Auto drains use solenoid valves for compressed air systems where air could be released to the factory floor.

Once the damage, leaks, or cracks are identified, it is important to assess the severity of the issue and prioritize so that you can improve the efficiency of your compressed air system in the best most cost-efficient way. There are various types of compressed air system inspections: visual, mechanical, calibration, and tests. When performing a visual or mechanical test, it is important to keep track of the condition of the equipment: good, dirty, cracked, etc. The age of equipment is important.  Piping and tubing over time can build up scale and corrosion. The debris that collects may require cleaning. The following equipment may require replacement: Filter elements, parts in air tools such as O-rings, and tubing.

If the equipment is dirty – then the inspector should tell the employee responsible to clean the equipment. If the equipment is cracked or damaged, the maintenance personnel should be informed so that they can determine the return on investment for either repairing or replacing the equipment.  Tracking the condition of your compressed air system is as important as conducting regular inspections.

 

Inspection List

“Treatment without prevention is simply unsustainable” – Bill Gates

“It is usually impossible to know when you have prevented an accident.” – Mokokoma Mokhonoana

Being proactive by inspecting your compressed air system regularly not only increases the life span of your equipment, but also your operation, maintenance, down-time, and replacement costs will decrease. Leaks divert up to 25 percent of your compressed air away from your system. Finally, it is an excellent source of information that is helpful in determining a return in investment for repairs.

Assessments could include an accurate Cubic Feet per Minute (CFM) scoring for objective measurement. Single stage air compressors may reach pressures of 150 PSI. A single stage pump has higher CFM rating than a two-stage pump since every cylinder compressing air during every rotation.

Here is a list of items to inspect on a daily, weekly, and monthly basis:

 

Daily

The following items need to checked most often:

• Listen for strange sounds
• Keep everything tight: accessories, nuts, bolts, anchors, and screws
• Check for leaks in the air inlet, receiver, delivery lines, coupling, filters, fittings, valves, and connectors.  
• Search for damage to external equipment or component parts
• Quality of pipes: Pipes that are clean, dry, and free of corrosion are great indicators of good quality tubing and hoses
• Wear and tear of equipment, especially piping. Check for damaged, aging, or cracks.
• Check for cracks in drive belts and coolers
• Aging disconnects for leaks
• Oil level on airline lubricators and replace oil regularly
• Compressed air enclosure temperature
• Operating temperature and pressure of the entire system
• Room ventilation temperature should be as cool as possible
• Clear and clean drain traps
• Look for decreases in:
  • Pressure
  • Dew point
  • Refrigerant pressure
• Check lubrication in the distribution system and valves
• Check air quality. It should be free of debris and dry
• Power supply to air compressor is working well
• Ensure that manual distribution condensate traps have not been left open
• Check accessories for wear, dirt, or leaks:
  • filters (oil and air),
  • separators (shims)
  • nozzles
  • pumps (air, vacuum)
  • fitted drive belts

Weekly

Dust and sludge corrode very quickly and increase leaking in compressed air equipment.  Keep the air in the system dry and filtered to reduce maintenance. It is recommended that you check the following weekly:

• Lines
• Gaskets
• Fittings
• Valves
• Clamps
• Connections
• Filters for dust, dirt, or sludge
• Tanks
• Condition of oil
• Compressor
• Check the coolant and refill it regularly since the coolant prevents your system from overheating and prolongs the life of your compressed air system.
• Use test buttons on electronic systems and manual bypass valve to ensure that all drain traps are working correctly

Monthly

The following items should be checked monthly:

• Examine your compressed air system system’s response to manufacturing requirements
• Calibrate sensors, controllers, and valves
• Access your factory’s true production level efficiency and determine areas of improvement
• Completeness of air compressor system assembly
• Equipment rotation
• Equipment identification, labeling and tagging
• Adequate working space for ventilation
• Control system
• Comparison to plans and drawings
• Safety devices
• Test the following for operation efficiency:
  • Air compressor
  • Air dryer
  • Water and oil separator (if applicable)
  • Pressure
  • Filter and traps
  • System test
  • Receiver system is stopping at the set maximum pressure

Most importantly, take notes and track your information so that you can identify trends and budget for future expenses such as repair and replacement of aging equipment. Information that is important to note includes: operating temperatures, pressure, flow, and levels.

 

After the Inspection

Regular inspections should be conducted by the same employee but if that is not possible track the personnel who did the inspection by recording the following information: Name, Designation, Contact Information, the Time and Date of the inspection with signature sign off. The inspection should be acknowledged by your safety liaison officer and manager. The approval of the inspection should be signed by the person responsible for inspection. Typically, the person responsible is the factory floor manager.

Nex Flow technical experts are happy to help you inspect, analyze, and recommend areas in your factory environment that could improve cost savings, reliability, and productivity.

COMPRESSED AIR USED IN THE FOOD INDUSTRY

The food industry is huge worldwide.  In the USA alone, there are approximately 1,300 facilities employing about 112,000 people mainly for canning, freezing, and dehydrating fruits and vegetables. This segment represents approximately 7.5% of the dollar value of shipments of the entire U.S. food industry¹. In many fruit and vegetable processing plants, compressed air systems are used for air cleaning of containers prior to product filling, automated product sorting, and product packaging systems². (1,2 Eric Masanet and Ernst Worrell, Lawrence Berkeley National Laboratory, “The Energy Star for Industry Program”, Compressed Air Best Practices Magazine®, October 2006, page 14-15)

There are tens of thousands of facilities in other segments of the food industry using compressed air. Some, like bakeries, use this technology for blow-off applications. Other segments use them to clean containers before filling. Additionally, compressed air is also used to sort, cut, shape and convey food products.  

Another applications are in form, fill and seal operations for cartons. Because these machines must be cleaned thoroughly and regularly to maintain sanitary standards, through washed-down pneumatic systems are preferred since hydraulic systems can have oil leak issues.  Pneumatic also has much less downtime and maintenance needs than hydraulic systems.

Compressed air is very important in the food industry, both for food processing and in the packaging operations.  The air must be contaminant free to ensure food quality and protection. There are standards in all developed countries to have a maximum micron content in filtration and also for dew point control. Dew points of the air at line pressure must be under minus 15 degrees oF (-26 degrees oC) to inhibit growth of microorganisms and fungi.

Some filtration companies, therefore, specializes in filters that meet particular standards of filtration necessary for various processes within food production facilities.

It is not only particulate but also oil which can be a concern.  Where necessary, oil- free compressors are used to supply the compressed air.  

CONTACT – NON CONTACT APPLICATIONS

Compressed air must be purified of contaminants before use in the food industry. The contaminants are water vapor and moisture, solid particulates (including spores) and oil aerosols and vapors.   

Moisture can often be trapped in the piping system near the point-of-use in applications where compressed air comes into contact with food products. Microorganisms and fungus can grow inside the piping system and then be blown into food products or containers. Drying the air to a specified pressure dewpoint is the simple way to eliminate moisture in the system.  The dew point specification can vary from +37 oF (+3 oC) or -40 oF (-40 oC). In some facilities, both of these specifications may be used depending upon whether compressed air has any possibility of coming into contact with food products.

Contact application is when the compressed air is used as part of the production and processing including packaging and transportation of food production or if compressed air comes into direct contact with actual food products. If this is the case, the compressed air needs to be purified to a higher standard than for non-contact applications usually to the -40 oF (-40 oC) dew point, with oil free air and very fine filtration to keep out particulate.

One way to accomplish this is with desiccant (adsorption) type compressed air dryers located in the compressor room (centralized air treatment). Each facility can determine if further point-of-use air dryers (de-centralized treatment) are needed. Point-of-use air dryers may be of either desiccant (adsorption) or membrane-type technology.

Another way to purify the compressed air is by using coalescing filters will remove solid particulates and total oil (aerosol + vapor). Activated carbon filters are usually required as well to remove oil vapors. As with the air dryers, de-centralized filtration may be needed in addition to the centralized filtration system.

Food plants are ideal applications for the use of engineered nozzles and air knives. These are used to blow off on a product and in packaging applications.  These accessories conserve compressed air consumption by utilizing the Coanda effect to entrain surrounding atmospheric air along with the compressed air and create a high velocity, high flow, and a high energy stream of air.


Some applications includes:
– Blow off water after washing a product prior to packaging
– Blow off excess sugar from muffins prior to oven to avoid burnt product
– Cool a product prior to packaging to increase line speed and shorten conveyor length

This air “amplifying” technology not only reduces compressed air energy consumption it also reduces noise levels and have a dead end pressure under 30 PSIG to meet OSHA safety standards on open compressed air exhaust contact.

Non-Contact applications can be categorized into high risk or low risk.  This is when the compressed air is exhausted into the local atmosphere of the food preparation, production, processing, packaging or storage.   

Example of a high risk application is where compressed air is used in a blow-molding process to create a package –then product is put into the package at a later time. Many food processors have their own in-house production lines to create their own packaging.  If there is a delay in the use of the packaging, oil, moisture, and particulates (notably bacteria) could be present if the compressed air is not pure enough. Hence the higher standard for cleanliness. 

In low risk applications higher dew point may be acceptable using a centralized refrigerated type compressed air dryer. Additional point-of-use air dryers (de-centralized) may still be required.  Significant portions (often over 50%) of compressed air in a facility will have absolutely no contact with food products or food-packaging machinery. In this case less costly methods for air treatment are acceptable.  Refrigerated type compressed air dryers normally have significantly lower energy costs than desiccant air dryers. Coalescing filters are required to remove solid particulates and total oil (aerosol + vapor) to the same specification levels as in contact applications and activated carbon filters will be required as well to remove oil vapors. As with the air dryers, each facility can determine if de-centralized filtration is required in addition to centralized filtration.

What are the Advantages of an Air Operated Conveyor System?

Air operated conveyors are clean, quick, and efficient machines that are designed to transport or vent a wide variety of lightweight products, raw materials, or fumes from one place to another. They are a family of devices that use air to move products instead of mechanical belts or chains. Internal air conveyor is the term used when the items being moved are in the same pipe or chamber as the air that is moving them. Air transporter systems are popular in material handling and packaging industries. It works by having air flow through louvers to an inner chamber in which items, such as metal scrap, is moved. Internal air conveyors are limited to lengths of about 100 ft. (30 meters) or less due to pressure losses within a pipe.  

Any friction between the product and the system is kept to a minimum. Some system even use ultra-low friction guide materials, such as oil-impregnated Ultra-High-Molecular-Weight (UHMW) or highly polished chrome.  At very high speeds, a week’s worth of dust on a line can create enough friction to reduce line efficiency. Therefore, it is important to keep surfaces clean in these type of systems.

An air conveyor system is used to convey all types of solids, plastic materials, metal pieces, waste, trim removal in a manufacturing environment. It can also be used to vent gas in some cases. The length of the distances transported vertically and horizontally depend heavily on the types of material you are conveying.

 

Different conveying systems are used according to various needs of different industries

• Bulk conveyors move powders, scrap, coal, bottle caps, and grain. Generally these are not used for delicate objects that could be damaged if not moved in a specific orientation such as bottles, although some heavier bottles are conveyed this way.  An air conveyor system can usually convey the same material as bulk conveyors but with significant less capacity. Low capacity applications where bulk system may apply can be ideal for air operated systems.

• Deck conveyors are used to move cans, caps, and cartons or cases. Deck conveyors work like air hockey tables, except that in addition to the lifting holes, there are directional louvers that direct products. It is not uncommon for deck conveyors to be inclined more than 10 degrees. Specialized systems called “tunnel tracks” are used for cans with decks on top and bottom, which sometime serve as vertical elevators.
  
  This type of carrier requires a guide to keep products from falling over. The guide keeps products from lifting off the conveyor and prevents products from tipping over when starting and stopping. Products without flat tops and bottoms may not work well with this specific system because they are not easily guided. However, there are some products/packages designed so they can be moved without a top cover. Other guide arrangements are also possible. For example, some air deck conveyed products such as plastic ketchup bottles may be guided on the shoulders rather than the top.

• Neck ring conveyors are used to move bottles. Due to the friction of the bottle-neck ring against the neck-ring guide, more air pressure is needed when bottles accumulate back to back to get them moving again.

• Airveyors are devices used for handling dusty materials, which is built on the principle of a pneumatic cleaner. The system used is a suction system, whereby the material (soda ash, salt cake, cement, or powdered lime) is drawn from the car through a flexible hose into a vacuum tank designed to recover a large percentage of the dust floating in the air. An air conveyor can sometimes be used and incorporated into these systems depending on the capacity that needs to be addressed.

• Apron Conveyor is made from linked apron plates with hinges on its underside, thus creating a looped carrying surface where huge and heavy materials are placed.  A mechanism, usually composed of several metal rollers, is placed inside the apron conveyor belt. The apron conveyor is used to deliver many materials across several phases of production. Many industries consider apron conveyors to be a lifeline in their industry, including manufacturing, agricultural, and chemical industries.

• Screw conveyor or auger conveyor is a mechanism within a tube that uses a rotating helical screw blade. It is used to move liquid or granular materials including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others.  The rate of volume transfer is proportional to the rotation rate of the shaft. Although air conveyors are not able to handle the large capacity that screw systems must deal with – rare application can arise.

• Chain Conveyors are used for moving products down an assembly line and/or around a manufacturing or warehousing facility. Chain conveyors are primarily used to transport heavy unit loads, e.g. pallets, grid boxes, and industrial containers. These can be single or double chain strand in configuration.This type of carrier system utilizes a powered continuous chain arrangement, carrying a series of single pendants. The chain arrangement is driven by a motor, and the material suspended on the pendants are conveyed.

• Bucket elevator (also called a grain leg) is a mechanism for hauling flowable bulk materials (most often grain or fertilizer) vertically.
• Vacuum Pump – while not specifically a type of conveying system, electrically operated vacuum pumps are utilized often for venting purposes to move gaseous products of all types, including corrosive gas products.   The gases are conveyed by the vacuum action and sometimes vented to the atmosphere. Air conveyors are better suited when handling corrosive or high temperature gas because they do not use electricity, can be supplied in appropriate materials, are lightweight and compact for easy installation, and virtually maintenance free.

 

Examples of air conveyors

• Ring Vac: Simply clamp a standard hose size to each end of the Ring-Vac to create high energy conveying system. There are no moving parts for maintenance free operation with capacity and flow controlled using a pressure regulator. Any size longer than  3” (76mm) can be prohibitive for most applications due to high compressed air requirements but 4” and 5” units are available.  The anodized aluminum and high temperature stainless steel Ring-Vac Air Conveyor can move all types of solids in large volumes over great distances with no moving parts.
• XSPC Conveyors: Like the Ring Vac, XSPC conveyors are compact, easy to use, portable, and ideal especially for intermittent use in material transfer.  The difference is that the inside of an XSPC conveyor is straight and smooth so materials, such as textiles, cannot clog.

Air conveyors are most widely used to move lightweight objects such as empty containers, boxes, and trays at speeds often exceeding 1,000 fpm. However, they are not limited to lightweight materials. There are many different types of air operated conveyor systems that are designed to convey different types of products or perform specific tasks.

What are the advantages of using an Air Operated Conveying Systems?

Air operated conveyors easily move items at faster speeds than conventional conveyors.  They are also ideal for moving scrap where conventional conveyors would become quickly clogged or contaminated with debris. The inside diameter can be twice the diameter of the part/material being moved to help prevent clogging.

Air conveyors typically have minimal moving parts and no pockets to collect debris and water, which makes them safe and easy to clean and maintain. The original patent was for coal since it was used to safely vent air in remotely for various explosion-proof settings. Coal comes in a variety of sizes and easily breaks down into smaller, highly flammable particles. Air conveyors are designed to keep coal dust contained and not attract and accumulate dust. This means that they require much less frequent cleanings than belt conveyors moving coal would need. Maintenance is also greatly reduced on air conveyors versus conveyor belts, because the only bearings are on the blowers, which are typically located well outside the area where they would encounter dust and other small particles.  

Air conveyors are also useful when transporting sharp or abrasive materials. Metal scrap and recycling centers are perfect applications for air conveyors because long ribbons of razor sharp metal can easily snag other types of conveying equipment.

Applications of Air Conveying Systems

• Venting Gas
• Combining Air Operated Conveyors with Air Amplifiers
• Hopper loading
• Trim removal
• Filling operations
• Material transfer
• Food ingredients
• Coal
• Grain
• Scrap
• Abrasive or corrosive chemical industry products and fumes

Venting Gas

In a transmission line or a scrubber, the compressed air technology replaces an electrically operated vacuum pump for venting purposes. Electrically operated vacuum pump requires maintenance and a more complicated configuration.

There are two options available depending on the nature of the gas that you want to vent:

• A compressed air flow amplifier, which utilizes the Coandă effect
• An air operated conveyor, Ring Vac and XSPC which uses a Venturi effect.

A compressed air flow amplifier is very quiet and moves large quantities of air. It is an ideal solution when venting clean gas short distances because very little vacuum is required. The compressed air exits a small gap in the amplifier and goes over a series of ” Coandă ” angles converting air pressure to flow. This solution is ideal for venting fumes, dust, and grime. It is complex to manufacture and costs more. This unit requires more air pressure to operate.

An air operated conveyor uses a series of holes to blow the compressed air in one direction creating a vacuum to draw in and move the gas. The Venturi system has several holes, the number depending on the size of the unit, which pulls the air behind the unit creating a vacuum, drawing in any gasses and then pushes them away. It is an ideal solution for moving gas longer distances aided by the extra vacuum. An air operated conveyor is required when the gas is contaminated and there is a possibility that it could deposit material on the Coandă angles of an amplifier, which could stop the venting effect over time.  Since the compressed air enters through a different vent, there is less opportunity for dirt deposits if the gas is contaminated. The air operated conveyor produces a higher vacuum but does not move as much air volume as an air amplifier. The Venturi system is a simple unit to manufacture and costs less. It requires less air pressure to operate. It is available in aluminum, stainless steel (standard), with special units made in Teflon, other plastics and metals.

Therefore, due to the design, cost of manufacture, and requires less air pressure to operate, the Venturi system is often the ideal solution for gas venting applications.

Combining Air Operated Conveyors with Air Amplifiers

If a large amount of air borne dust or fumes need to be collected and moved a long distance, the air amplifier enhances the air conveyor ability to convey these materials over long distances. The reason is that air conveyors produces high vacuum but move less volume as compared to air amplifiers that move high volume but creates less vacuum.

 

How do I select an Air Conveying System?

The factors to consider are:

• Material properties: Consider the characteristics of the material that needs to be moved or removed. What is the particle size and shape, bulk density, moisture content, abrasiveness, friability, cohesiveness, static charge, explosivity, toxicity, melting point, and more?
• Conveying distance: What is the overall distance as well as horizontal or vertical direction of the pipe?
• Available air pressure and velocity
• Transfer capacity: Includes the material properties and the transfer distance.
• Transfer rate: How fast and how often does the material need to be transferred.
• Energy Consumption: Compressed air supply availability

Accessories and Attachments

• Mounting bracket to mount the air operated conveyor
• Clamp to stabilize a hose to each end
• Threaded to thread on a standard pipe for threaded units
• Inlet suction attachment
• Air filters
• Air Regulators
• Air Amplifier

Using Compressed Air Operated Conveyors for Conveying

In utilizing compressed air operated venturi systems such as Nex Flow’s® Ring-Vac®Air Operated Conveyors, you size the unit based on the size of the parts being conveyed.

The general rule is to have the inside diameter of the unit to be double the maximum size or dimension of the parts being conveyed. In this way there is little chance of the parts clogging the unit.

However there are exceptions. One customer for example, had to move a metal rod from one part of the factory to another. This enterprising company utilized the Nex Flow® 2″ Model 30004 Ring-Vac®. The company fed a 1” diameter but 4″ long metal rod into the unit and used the venturi to convey the rod from one end of the factory to another reducing handling time dramatically.

The rod was made to fall onto a gravity feed slot which feeds the rod into the Ring-Vac®. Air is conserved by turning it on only when there is a rod to feed and this is controlled by a sensor. The rod is then literally shot 15 feet up to the ceiling area in a plastic tube connected to the Ring-Vac®. At the ceiling, the feeder tube is then angled about 2 degrees downward where the part is then gravity fed in the tube, across the ceiling, to the other end of the factory which of course, requires no energy.

The part drops out into a bin at the exit of the tube where it is manually picked up for further processing at another machine station. Intermittent applications such as this are ideal for such technology since the unit is low cost, compact, with no maintenance and operates instant on and off only as needed. The use of gravity to feed the part from one end of the factory to the other was brilliant.

Can you think of other applications like this??

Why is the Compressed Air Pressure Too Low

As discussed in this video, there are causes and solutions to situations where the compressed air pressure is too low for some factory applications.

All equipment that uses compressed air is designed to operate at a certain minimum air pressure entering that equipment.   If the pressure at the point of entry is too low, the equipment can slow down, not work as well, or cease to operate entirely.

One of the common things done, but which should be avoided, is to increase the pressure output of the air compressor.  This generally yields more pressure at the point of entry to the compressed air-consuming device.  But it increases energy consumption needlessly.

It is better to address the causes of where the pressure is being lost in the transmission of the compressed air to the air-operated device.   This can be many things as explained in the blog.

Nex Flow Air Products Corp. manufactures specialized compressed air products for blow-off, cooling, drying, and moving and provides accessories such as special filtration technology for improving compressed air systems and optimizing compressed air use.
