EXAIR's low cost Sintered Bronze Mufflers are easy to install in new and existing exhaust ports of valves, cylinders and other air powered equipment. Each Sintered Bronze Muffler is capable of passing a certain volume of air with minimal back pressure restriction so it doesn’t interfere with the operation of the cylinder or valve.

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.

Straight-Through Silencing Mufflers feature a corrosion-resistant aluminum outer shell lined with sound-absorbing foam for better noise reduction. The typical noise reduction is up to 20 dB.

Heavy Duty Silencing Mufflers feature a corrosion-resistant aluminum outer shell with an internal stainless steel screen that protects valves and cylinders from contamination that could enter through the exhaust ports. !is also keeps contaminants such as rust from being ejected at high speed from the exhaust port. The typical noise reduction is up to 14 dB.
