(0.35 bar) pressure drop: 140 scfm (66 dm

/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.
