Neo-Muff silencers are designed to muffle the annoying and distractive noise of Diaphragm Pump exhausts. An efficient and inexpensive addition to your pump, they are recommended for expiators, suction apparatus, vacuum frames, checks, simulation chambers, transfer and control devices etc. --- where quiet and efficient pump performance is essential. Attenuation of the irritating pulsations is achieved by an obstruction-free expansion chamber, from which the exhaust air, at lowered velocity is softly dispersed through the openings in the large area cylinder wall disseminator of the muffler ---- free of noise and without causing mechanical impedance. Mufflers are ordinarily supplied with standard pipe threads for direct connection to the exhaust port of nf series models. Unit should be mounted in a protective position, free from excessive vibration. Use wrench on hex head to tighten unit to the device. These Mufflers are constructed entirely with corrosion-resistant materials. | | | | | | | | | | | | | | |
