Frantz, V L

A precoalescer unit for a twin tower assembly for decontaminating compressed gas the towers of which each contain a desiccant and under timer control of individual solenoid valves alternately receive contaminated gas and individually cycle bewteen decontaminating and regenerating cycles, the precoalescer unit being interposed in the path of flow of contaminated gas from a source to the towers' inlet ports and having a casing and a double-seated drain valve on the casing and connected for actuation to an actuating gas line of one of the towers, the casing containing an open-ended in-out tubular coalescer and avalve in and normally closing a lower end of the coalescer and opening under differential pressure on opening of the drain valve for enabling the precoalescer unit, in response to cycling of the towers, to be purged cyclically of coalesced oil drained by gravity from the outside and contaminants washed from the inside of the tubular coalescer by combressed gas received from the source.
