If you’ve been tasked with reducing operating costs in your plant, upgrading your blowoffs to EXAIR’s Engineered Air Nozzles & Jets might be just the ticket. When replacing a homemade or inefficient solution, EXAIR’s Super Air Nozzles can save you as much as 80% of your compressed air usage.
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 prevent 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.
If your process involves numerous different products with varying dimensions, you might need a way to adjust each blowoff based on the material being run. With our Stay Set Hoses, this can be achieved quickly and easily without the need for any tools or a long shutdown.
EXAIR’s Stay Set Hoses are available from 6”-36” in length with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend. They’re easily repositioned as well, making them an ideal solution for applications that may require frequent repositioning due to varying parts.
All of these products are available to ship same-day with an order received by 2:00 ET from stock. Give one a try today!
