When compared to commonly used, open copper tubes or pipes, Air Jet compressed air savings can be as high as 80%. With less compressed air moving out of the Air Jet, sound levels are reduced to a manageable level. 10 dBA noise level reductions are typical. All EXAIR Air Jets are compliant with OSHA guidelines for dead end pressure and sound level exposure.
EXAIR Nozzles and Jets are designed and manufactured to take advantage of the Coanda (wall attachment of a high velocity fluid) effect which can amplify the airflow volume up to 25 times. The compressed air exits through a small gap in the nozzle area (#1) which entrains the surrounding air from behind the nozzle. Additional air volume is entrained from behind and around the output of the Air Jet (#2) to provide the user with an “amplified” or multiplied airflow at (#3) to do the work or provided the intended effect desired. More force with less air consumption and less noise is the goal.
The Air Jets are supplied with 1/8 NPT male threads and blow air out at a right angle from the inlet. They produce a vacuum on the larger diameter side which pulls in surrounding ambient air into the total output flow. Air Jets are available in brass or Type 303 stainless steel. You can choose from a fixed flow style or an adjustable flow style to provide flexibility for your applications. The adjustable flow models have a clear micrometer air gap indicator on the side of the body, opposite the inlet, to assure consistent and accurate results. All of our Air Nozzles and Jets 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. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels. This means you can operate them with input pressures well above 30 PSIG to get harder hitting forces while still remaining OSHA compliant. This ability for our Air Jets to accomplish this task is where the rubber meets the road so to say.
EXAIR’sSwivel Fittings Make it easy to adjust the position of the Air Jets. The fittings allow for movement of up to 25° off axis for a total movement of 50°. There are nine different models available and all of them are made from stainless steel
