ABSTRACT:
Two-stage precoalescer unit for filtering, coalescing and separating from contaminated compressed gas loose oil and water in a first stage and oil and water aerosol or vapor in a second stage, the coalescers of the first and second stages being mounted in tandem in a perforate-walled canister contained in a housing within an imperforate tube, the first-stage coalescer relatively permanently for periodic purging by gravity and a reverse flow of gas and the second-stage coalescer removably, for purging over an extended period by a reverse flow of purge gas and thereafter removal and replacement on detachment of a lower from an upper part of the housing, and a spring-pressed floating follower in the housing above and acting downwardly on the canister for compensating for manufacturing tolerances in components of the precoalescer unit.
