Muffler to Quite Noise From High Velocity Steam and Air Atmospheric Venting.
When steam, air, and other gases are vented to atmosphere at high velocities noise is created. Typically the higher the velocity the louder the noise level. Penn makes two models of Exhaust Silencers to reduce noise levels. Our "SP" full sized unit provides maximum noise reductions of 34-46 dB(A) or choose our SP-S short version that provides noise reductions of 24-30 dB(A). A wide range of sizes 2" through 24" are available.
