Upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets can save as much as 80% of your compressed air usage when compared with an inefficient solution. 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 and pipe 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 subject to an OSHA inspection. Inspections are typically unannounced, so it’s important to take a look around your shop and make sure you’re using approved products.
To ease the installation process, EXAIR manufactures a line of swivel fittings that allow you to position the blowoff precisely. Manufactured in either 303 or 316 stainless steel, the Swivel Fittings allow for movement of 25 degrees from the center axis for a total movement of 50 degrees. With no gaskets or seals to wear out, ther’es no added maintenance required to maintain optimum performance.
Swivels can be used on any of our Air Nozzles up to 1” and can also be used with the Adjustable and Super Air Amplifiers. By simply adding a “W” suffix to the part number, the correctly sized swivel fitting will be added to your order. For example, an 1122W would be one of our 2” Flat Super Air Nozzles with a ¼ NPT male x ¼ NPT female Swivel Fitting included. Stop wasting time trying to find the proper fittings and positioning for your blowoff nozzles!
