Watts 0858549|WW0858549 - AS-MB-FL Flanged

This flanged FPT microbubble air separator is designed for efficient separation and elimination of entrained air in hydronic heating systems. The flanged end connection can accept multiple size flanges from 3/4, 1 and 1-1/4 inch sizes. This air separator features a durable brass body, high capacity DuoVent air vent assembly, corrosion-resistant coalescing media and 1/2 IN FPT bottom tapping for use with boiler fill fitting. The rugged corrosion-resistant polyphenylsulfone (PPSU) coalescing media withstands petroleum based cleaners, glycol anti-freeze and temperatures up to 240 degrees F in heating systems and methanol based anti-freeze solutions in ground-source heat pump loops. No minimum inlet/outlet piping length is required for proper operation and this air separator can be easily disassembled for inspection and cleaning.
