Designed to muffle the distracting noise of vacuum pump exhausts, the Atomuffler® Vacuum Pump Exhaust Muffler is an efficient and inexpensive addition to any pump. Noise reduction is achieved by an obstruction-free expansion chamber that reduces exhaust air velocity and softly disperses it throughout the muffler’s large disseminator surface area without causing mechanical impedance. The Vacuum Pump Exhaust Muffler is recommended for applications where quiet and efficient pump performance is critical, such as in suction apparatuses, vacuum frames, checks, simulation chambers, and transfer and control devices.
