EXAIR 9073 1/2 NPT Muffler/Reclassifier

Reclassifying 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 also 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 1910.1000, a worker’s cumulative exposure to oil mist must not exceed 5mg/m3 by volume 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 an intake of 50 PPM at 100 PSIG, the Reclassifying Mufflers reclassify and reduce the exhausted oil mist to 0.015 PPM. A reservoir where oil accumulates at the bottom can be drained by attaching a 1/4" tube.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 (see Options in left nav) helps you select the appropriate model based on the actual bore and stroke of the cylinder.EXAIR Silencing Mufflers, in popular NPT Sizes, help to reduce work area noise produced by air exhausting from cylinders, valves and other air powered equipment. Per OSHA Standard 1910.95 (a), worker must not be exposed to sound levels above 90 dBA for any eight hour shift of a 40 hour work week. Silencing Mufflers help plants meet this OSHA requirement by reducing the sound to safe levels below 90 dBA. They also eliminate harmful dead end pressures. Each style of Silencing Muffler shown has a high airflow capacity, with low back pressure.
