How Air Nozzles Works

For the Standard Air Nozzles Models 47001, 47002, 47003, 47003S, 47003S-316L, 47004, 47004S, 47004S-316L, 47009, 47009S, 47009S-316 they work utilizing the Coanda effect by entraining surrounding air along wit the compressed air that exists a ring of holes around the bottom of the nozzle.  Compressed air enters at point (A).   Surrounding air (B) is entrained over the specially designed profile surface by the action of the small amount of compressed air leaving the ring gaps at point (C). This results in a concentrated high velocity, laminar flow stream of amplified air.   With this deign energy normally lost as pressure drop and noise is recovered and converted into useful high energy flow.   The standard air nozzles provide the best flow/unit air consumption and are best suited for light blow off and for cooling applications.  Savings in compressed air compared to open pipe is around 30%.

The Standard Air Nozzles are low cost solutions to many blow off applications when light blow off is adequate.  Always use filters compressed air to make sure the air supply remains clean and dry.   Wherever there is an open tube or pipe, these air nozzles are a very lost cost way to reduce noise, reduce energy and improve safety as dead end pressure is below 30 PSIG and meets OSHA safety standards.

Materials vary in how the nozzles are made.  The Model 47001 and 47002 is made of brass.  Stainless steel is available on special order.  The other sizes are anodized aluminum, 304 stainless steel and 316L stainless steel for food and pharmaceutical applications.
