• Features a durable brass body construction, corrosion-resistant polyphenylsulfone coalescing media that withstands petroleum based cleaners, glycol anti-freeze Requires no minimum inlet/outlet piping length for proper operation DuoVent air vent assembly has a high capacity and high temperature rating Fully serviceable, can be disassembled for inspection and cleaning Bottom tapping for use with series RBFF residential boiler fill fitting For use with glycol systems or for use as an anti-vacuum device

This 1 in FPT 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 and temperatures up to 240 deg 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.
