EXAIR’s Air Nozzles & Jets: The Engineered Alternative to Cheap or Homemade Blowoffs


 If one of your goals is to reduce air consumption in your facility, look no further than EXAIR’s Engineered Air Nozzles & Jets. By upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets you can save as much as 80% of your compressed air usage when compared with an inefficient solution.

EXAIR engineered nozzles are designed to optimize your compressed air system by entraining ambient air along with the supplied air, providing maximum force on the target. Inefficient solutions are commonly used in the form of cheap, plastic nozzles and sometimes even worse, open pipes or tubes. An open copper pipe or tube, even if “flattened” as we’ll commonly see, wastes an excessive amount of compressed air. This wasted compressed air can create problems in the facility due to unnecessarily high energy costs and the pressure drop that can be experienced affecting other processes. In addition to simply using too much compressed air, an open pipe or tube will often produce sound levels in excess of 100 dBA. At these sound levels, according to OSHA, permanent hearing damage will occur in just 2 hours of exposure.

By simply replacing the open tubes/pipe or inefficient solutions with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND reduce the sound level. Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding an open pipe blowoff, in addition OSHA 1910.242(b) states that a compressed air nozzle used for blowoff or cleaning purposes cannot be dead-ended when using with pressures in excess of 30 psig. I don’t know if you’ve ever tried to use an air gun with 30 psig fed to it, but the effectiveness of it is dramatically reduced. This is why there needs to be a device installed that’ll prevent it from being dead-ended so that you can operate at a higher pressure.


EXAIR’s Super Air Nozzles are designed with fins that serve two purposes. They help to entrain ambient air from the environment, allowing us to maximize the force and flow from the nozzle but keeping the compressed air consumption minimal. In addition, these fins are what prevents the nozzle openings from being completely blocked off. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual infraction will result in a fine if you’re unfortunate enough to be the victim of an unannounced OSHA inspection.

EXAIR carries a wide range of sizes and materials of nozzles, so you should have no trouble identifying one suitable for your application.If the savings in compressed air alone isn’t enough incentive, some energy providers offer rebate programs for the implementation of an engineered compressed air nozzle. If you need help selecting the best nozzle for your process, give us a call. An Application Engineer is ready and waiting to help analyze your process and recommend the best option.
