Adjustable Air Amplifiers

Product Overview

Nex Flow™ Adjustable Air amplifier is lightweight, machined anodized aluminum or stainless steel.  The aluminum units are popular with OEM’s due to their compact design, light weight, and low cost.  Stainless steel units are utilized in high temperature, and/or corrosive environments as well as for medical, food, and pharmaceutical installations.   Suitable for most applications for blow off, cooling, or venting, these adjustable units can have their gap setting anywhere from .001” to .004” to control the output flow and force required.  Once the gap is set, an O-ring locks the setting into place. The systems utilize the Coanda effect like the Standard Air Amplifier version to create a powerful, amplified, and high velocity laminar flow of air.

The Adjustable Air Amplifier from Nex Flow™ is light weight so it can be held in place by the feed piping, or can be clamped into place.   An optional Mounting Bracket is available for the 1-1/4” and 2” units with mounting holes to make them attachable like the Standard Air Amplifiers.  These maintenance free units reduce both compressed air consumption and noise levels and are easy to use, and can amplify airflows up to 17 times their input air consumption rate.  Four sizes are available in either anodized aluminum or stainless steel – ¾,1-1/4”. 2”, 4”.

The annular shape of the adjustable air amplifier make them ideal for blow off applications where they have to get into corners or curved shapes such as the tops and bottoms of cans, round containers and similar shapes, to scoop out liquid from corners.  For cooling applications, the most commonly used sizes are the 1-1/4” and 2” units. The adjustable gap setting from .001” to .004” can be set to have the rate of cooling (and force and flow) required. In venting applications, they entrain a large volume of surrounding air.  They are often used to remove dust from grinding and weld fumes. The lightweight aluminum units in particular can easily be mounted to robotic systems due to low weight and compact design.

Either end of the Adjustable Air Amplifier may be ducted using hose or pipe to collect or transfer light materials, fumes, and dust.  When ducted at either end, it reduces the air amplification to about 10:1 but still moves significantly more volume than alternative methods of venting.

Although available in anodized aluminum or stainless steel, other materials can be made on special order.  For example, plastic units were provided to cool components in an electrical power grid as metal could not be used.  In corrosive environments where even stainless steel does not hold up well, alternative materials can be machined. Nex FlowTM can also design special sizes and versions for unique applications to suit your requirements.

  How The Adjustable Air Amplifier Works

A large volume of surrounding air is induced into the amplifier at point (A) by the action of a small amount of compressed air which enters the annular chamber at point (B) that is then throttled through a small ring nozzle at high velocity and into the inside of the amplifier over a Coanda profile. The compressed air stream clings to the Coanda profile as it enters the inside walls of the amplifier and thereby creating a vacuum that induces the outside air converting the pressure into the amplified airflow. The amplified of airflow leaves at the exit at point (C). Airflow is further amplified downstream at point (D) by entraining additional air from the surroundings at the exit.

Performance

Air Consumption

Anodized aluminum adjustable Air Amplifiers come with three standard outlet (outside) diameters: 1-1/4″ (31mm), 2″ (51mm), 4″ (200mm). Other sizes available upon request.
Come standard with a .002″ (.05mm) gap. If greater air force is required, the gap is adjustable.
