Typical flow with a 40 µm element at 90 psig (6.3 bar) inlet pressure and 5 psig
(0.35 bar) pressure drop: 140 scfm (66 dm 3 /s)
Manual drain connection: Will fit 1/8-27 and 1/8-28 pipe thread
Automatic drain connection: Will fit 1/8-27 and 1/8-28 pipe thread. - Flexible tube
with 3/16" (5mm) minimum I.D. can be connected to the automatic drain. Drain
may fail to operate if the tube I.D. is less than 3/16" (5mm). Avoid restrictions in
the tube.
Automatic drain operating conditions (float operated):

pressurized. The drain opens when the float rises due to accumulated liquid
and on depressurization.
