EXAIR Air Guns Increase Safety And Reduce Air Use

Many times we receive calls from customers that fall right in line with our focus here at EXAIR  – providing Intelligent Compressed Air Products that improve overall safety for operators and plant personnel in industrial operations as well as reduce compressed air usage, ultimately lowering energy costs. Such was the case last week when I received an inquiry from a customer who was looking for a handheld device that could easily attach to their existing air hose to replace the loud and inefficient homemade air nozzles they are currently using to blow off steel chips and coolant from their saws and drills. Their current set up includes a combination of smashed air guns, similar to the one shown below, some small open tubes and cheap plastic nozzles. The blowoffs were working but their operators were starting to complain about excessive noise during operation and notice the compressor in the area was running continuously during the cleaning cycle. Their first proposed solution was to lower the supply pressure which did lower the sound level and air usage somewhat, but now the exiting airflow wasn’t powerful enough to clear the debris. After doing an internet search they decided to reach out to EXAIR for assistance.

Crushed guns create high pitch wind shear and provide no relief path for the air to exit safely

All of the Safety Air Guns we offer utilize our Air Nozzles which are engineered to meet or exceed OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels. As the Standard reads, when employees are subjected to sounds in excess of 90 dBA, some type of engineered controls should be used to lower the sound to a permissible level. Prolonged exposure to excessive noise can result in serious health issues, like tinnitus or a constant ringing of the ears, as well as stress and reduced productivity. In addition, our engineered Air Nozzles cannot be dead ended, meeting OSHA Standard 1910.242(b). With the design of our Air Nozzles, there is always a safe path for the air to exit so the outlet pressure will not reach 30 PSIG if the nozzle exhaust were to be blocked or pressed against the skin.  Due to this design, our units are safe to operate at higher pressure, resulting in a high velocity, forceful airflow.

Model 1210 – Soft Grip Safety Air Gun

For this application, I recommended the customer use our Model # 1210 Soft Grip Safety Air Gun. This particular unit incorporates our Model # 1100 Super Air Nozzle which produces a low sound level of 74 dBA, well within the OSHA guidelines, and consumes only 14 SCFM @ 80 PSIG while having the necessary power to solve their application.
