Exhaust Filters

The most common heard complaint about oil-filled vacuum pumps is the messy oil mist that comes from the exhaust. Whenever large volumes of air are pumped through a vacuum pump, there is a high probability of oil mist discharging out the exhaust port.

To minimize this occurrence, A-VAC recommends the use of high quality oil mist exhaust filters on all oil-filled vacuum pumps.

Available in all standard CFM and flanges sizes, A-VAC exhaust filters feature 99.97% trapping capability. Shipped complete with replaceable element and o-ring sealed lid.

Below are listed the most popular models of A-VAC exhaust filters, along with the appropriate replacement filter elements. Please inquiry about additional sizes and configurations.
