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 uses a special material that traps tiny oil droplets. The droplets join together and get bigger. Then gravity pulls the oil back down into the pump .

This is a pack of two replacement filter elements. The kit includes:

• Two filter elements (18973/S) – These are the actual filters that catch the oil mist .

• One ARS cover gasket (P20009121) – Seals the cover of ARS style exhaust filters .

• Two Viton gaskets (P23955165) – General sealing gaskets for the filter housing .

You get two filters in one box. That means you have a spare ready for next time, or you can service two pumps at once.

These filter elements fit several Leybold Trivac pumps :

• D25B and D25BCS (chemical series)

• D40B and D40BCS (chemical series)

• D65B and 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 .
