⚠️ Removing a pressurized air filter bowl could cause serious injury. Depressurize air line before servicing.

Pump systems have two air filters: the 5 micron air manifold filter (209) and the 40 micron pump air filter (206). Meter systems have only the 5 micron filter (209). Check filters daily and replace element(s) as needed. Order 15D909 (5 micron) or 15D890 (40 micron).

Close main air shutoff valve on air supply line and on system. Depressurize air line.

Remove and replace element (206a, 209a).

Screw filter bowl (B) on securely. Install cover (A).

Note: Check Fluid Filter Daily.
