High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA (Occupational Safety and Health Administration) noise level exposure requirements, resulting in hearing loss to those working in close proximity. The sound level of the Full-Flow Air Knife is quiet at 80 dBA, even at high pressures of 80 PSIG (5.5 BAR). Using the Full-Flow Air Knife, it is possible to obtain hard-hitting force without the high noise.
