Silencers

Vaccon silencers are extremely effective in reducing air exhaust noise from venturi pumps and other pneumatic devices. Vaccon silencers reduce noise levels by up to 30dB while allowing high flow rates with minimal back pressure.
AA Series Silencers AA Series Silencers
AA Series silencers have excellent noise reducing characteristics with minimal resistance to air flow. AA Series silencers are one third smaller than comparable products, providing considerable space savings. The large surface of the felt element resists contamination far more than other materials such as sintered bronze, steel mesh or porous polyethylene.
ST Series Silencers ST Series Straight Thru Silencers
The ST Series Silencers are designed with a straight through flow path that eliminates clogging by allowing the contaminants to pass directly through the silencer. Each silencer is tuned in proportion to its exhaust flow to minimize noise.

As air passes through the silencer, the dense felt element absorbs the noise, thus reducing high pitch exhaust noise to a gentle, low frequency sound. Even in the most adverse conditions, contaminates pass through the silencer making the ST Series ideal for silencing vacuum pumps that are continuously ingesting dirt and debris.
STAA Series Silencers STAA Series Hybrid Silencers
A hybrid silencer that offers increased noise reduction by combining an ST silencer with an AA silencer. The (closed-end) AA silencer is attached to the end of a modified ST silencer, thus removing the flow through feature of the standard ST Series silencers.
FA Series Hi Flow Silencers FA-51 Series SuperFlow Silencers
The FA-51 Series silencers offer remarkable noise reduction for high volume exhaust applications without causing back pressure. These silencers are ideal for quieting large air valves that must exhaust quickly to maintain high cycle rates. Vaccon uses the FA-51 silencers on all high flow venturi vacuum pumps where even a small amount of back pressure would decrease performance.
