How to Route Air Lines for Automatic Filter Drain
How It Works
Condensation (1) rests in the bottom of the filter housing,
waiting for the drain to be actuated.
Pilot signal from air dryer received
Valve at Rest

When pilot signal is relieved (6), piston returns to relaxed
position (7), ball check closes (8), preventing zero pressure
loss in system; drain port (9) opens and stored condensate is
ejected from the drain port.

Pilot signal (3) causes piston to shift (4), closing off drain port
(9). As piston continues to move it opens up the stainless ball
check (8) allowing condensate to be forced into the internal
reservoir creating a discharge pressure
Route a pilot line from the pilot signal port, located on the
bottom of the drain, to "T" fitting on the SFD Dryer.
Run a drain line from the drain outlet (located on the side of the
drain) to an appropriate discharge and collection location
