EXAIR Nozzles

EXAIR’s Engineered Air Nozzles and Air Jets offer an effective solution for reducing both compressed air consumption and noise levels during blow-off operations. Compared to traditional open copper tubes, pipes, and standard air nozzles, these products can achieve compressed air savings of up to 80%. This significant reduction in air usage also leads to a notable decrease in sound levels, with an average noise reduction of 10 dBA. Furthermore, all EXAIR Air Nozzles and Jets comply with OSHA standards regarding dead-end pressure and sound exposure limits.

EXAIR Nozzles are expertly engineered to utilize the Coanda effect, which enhances airflow by up to 25 times through the attachment of high-velocity fluid to surfaces. Compressed air is released through small openings in the nozzle, drawing in surrounding air and creating a powerful blast of high volume and velocity while consuming less compressed air. The company offers a diverse range of air nozzles, from the compact yet potent Atto Super Air Nozzle to the larger 1-1/4 NPT Super Air Nozzle. Additionally, EXAIR provides Flat Super Air Nozzles and Back Blow nozzles, specifically designed for cleaning tubes, pipes, channels, or holes ranging from 1/4 inch to 16 inches in diameter.

Our Air Nozzles are designed to comply with or surpass OSHA Standard 1910.24(b) regarding dead-end pressure at 30 PSIG. They are engineered to prevent dead-ending, ensuring that there is always an escape route for the air, which means the outlet pressure will not reach 30 PSIG. Furthermore, our products adhere to OSHA Standard CFR 29 – 1910.95(a) concerning permissible noise exposure levels. EXAIR Air Jets leverage the Coanda effect to enhance air movement in their environment. A small volume of compressed air is accelerated through an internal ring nozzle at supersonic speeds, creating a vacuum that draws in significant amounts of surrounding or ‘free’ air. The resulting exit flow is a mixture of these two air sources.

EXAIR produces two types of air jets: High Velocity and Adjustable, crafted from brass and Type 303 Stainless Steel. The High Velocity Air Jet features a replaceable shim that allows users to adjust the gap, thereby regulating the air’s force and flow. In contrast, the Adjustable Air Jet does not utilize a shim; instead, it incorporates a micrometer gap indicator and a locking ring, enabling users to modify the performance in terms of force and flow as needed.

Air Nozzles and Jets what ever the Application we have you Covered!

Intelligently Designed Compressed air nozzles, where do we start? EXAIR has over 30 different nozzles, (not including different materials and connection styles) so It’s safe to say we are going to have one for you!

EXAIR’s Engineered Air Nozzles and Air Jets provide a superior solution to minimize compressed air usage and reduce noise levels for compressed air blow-off operations.

Air Nozzles and Jets – when compared to commonly used open copper tubes, open pipes, and commercially available air nozzles the compressed air savings can be as high as 80%. With less compressed air, sound levels are greatly reduced.  A 10 dBA noise level reduction is typical.  All EXAIR Air Nozzles and Jets meet OSHA guidelines for dead end pressure and sound level exposure requirements.

Family of Nozzles

EXAIR Nozzles are designed and manufactured to take advantage of the Coanda (wall attachment of a high velocity fluid) effect which can amplify the airflow up to 25 times. The compressed air exits through the small holes on the nozzle which entrains the surrounding air. The effect from this is a high volume, high velocity blast using less compressed air.  EXAIR manufactures many sizes and styles of air nozzles from the smallest, but quite powerful Atto Super Air Nozzles to our largest 1-1/4 NPT Super Air Nozzle.  We also offer Flat Super Air Nozzles, and the Back Blow style nozzle for cleaning out tubes, pipes, channels or holes from 1/4″ to 16″ in diameter.

All of our Air Nozzles are engineered to meet or exceed OSHA Standard 1910.24(b) for 30 PSIG dead end pressure, they cannot be dead-ended as there is always a route for the air to escape so the outlet pressure will never reach 30 PSIG. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels.
EXAIR Air Jets also utilize the Coanda effect to produce air motion in their surroundings.  A small amount of compressed air (1) is throttled through an internal ring nozzle above sonic velocity.  A vacuum is produced, pulling in large volumes of surrounding, or ‘free’ air, through an around the jet (2).  The exit flow is the combination of the two air sources (3).

How an Air Jet Works

EXAIR Manufactures Air Jets in two types, High Velocity, and Adjustable with materials of construction of brass and Type 303 Stainless Steel.  The High Velocity Air Jet uses a changeable shim to set the gap, controlling the force and flow of the air.  The Adjustable does not use a shim, and has a micrometer gap indicator and locking ring to allow for varying force and flow performance.

If you would like to discuss blow off, noise levels, dead end pressure or any of EXAIR’s intelligent compressed air usage solutions, I would enjoy hearing from you…give me a call.
