Reclassifying mufflers from Exair reduce the noise from cylinders, valves, and other air-powered equipment. In most installations, typical noise reduction is up to 35 dBA. In addition, the removable element’s wrap design separates oil from exhaust air so virtually no oil is released into the environment. For instance, based on an intake of 50 ppm at 100 psig, the reclassifying muffler reportedly reduces exhausted oil mist to 0.015 ppm.
