An aftercooler condenses the water; it does not remove it. The condensate leaves the cooler as a mist carried in the air stream, and a centrifugal separator is what takes it out. IPAC separators spin the air past a fixed impeller so the heavier droplets are thrown to the wall and drain to a sump, then an anti-re-entrainment baffle stops them being picked up again. There are no moving parts and no element to replace, and the separator holds 99 percent efficiency down to 20 percent of its rated flow.
The sump then has to be emptied without losing air, which is the drain trap's job. The SAC float trap discharges upward as it fills, has a hand blow-down valve for a daily check, and is offered in aluminum, cast iron, carbon steel and stainless steel bodies for pressures from 150 to 1,010 PSIG.

A selection comes together quickly once the duty is stated.
Where a unit is being replaced, the nameplate does most of the work.
