AS-MB-S-125 RAD

This 1 1/4 IN sweat microbubble air separator is designed for efficient separation and elimination of entrained air in hydronic heating systems. 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, 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.
