Leybold Exhaust Filter Kit – Pack of 2 AF/ARS Element Part# 18973

An exhaust filter sits on the pump’s outlet. It catches the oil mist before it leaves the pump . The filter is often called a “demister” or “oil separator” .

The filter uses a special material called borosilicate micro-fiber . This material traps tiny oil droplets. The droplets join together and get bigger. Then gravity pulls the oil back down into the pump .

These filter elements fit several Leybold Trivac pumps :

• D25B

• D25BCS (chemical series)

• D40B

• D40BCS (chemical series)

• D65B

• D65BCS (chemical series)

They also fit the exhaust filter housings themselves. If your pump has an AF 40-65, AR 40-65, or ARS 40-65 exhaust filter, these elements are the right fit .
