Reclassifying Mufflers

Reclassifying MufflersReclassifying Mufflers are an upgrade from Sintered Bronze Mufflers. They offer the best noise reduction - up to 35 dB. Available from 1/8 NPT through 1 NPT. Reclassifying Mufflers eliminate oil mist. Exhaust air from cylinders and valves often contain oil mists that can contaminate the workers' breathing air, affecting their health. Per OSHA standard 29 CFR 1910.10, a worker’s cumulative exposure to oil mist must not exceed 4.32 PPM (particles per million) in any eight hour shift of a 40 hour work week.

The patented wrap design of the removable element separates oil from the exhausted air so virtually no oil is released into the environment. Based on the intake of 50 PPM at 100 PSIG, the Reclassifying Mufflers reclassify and reduce the exhausted oil mist to .015 PPM. A reservoir where oil accumulates at the bottom can be drained by attaching a 1/4" tube.

Reclassifying Mufflers

Each Reclassifying Muffler passes a certain volume of air with minimal back pressure restriction so it doesn’t interfere with the operation of the cylinder or valve. When used with cylinders, the “Muffler Quick Pick” table helps you select the appropriate model based on the actual bore and stroke of the cylinder.
