Description for Watts 0858547


Durable forged brass body construction. Series AS-MB does not require laminar flow for efficient separation and elimination of entrained air in hydronic heating systems. There is no minimum inlet/outlet piping length required for proper operation of AS-MB Microbubble Air Separators.

Rugged, polyphenylsulfone (PPSU) coalescing media withstands petroleum based cleaners, glycol anti-freeze and temperatures up to 240º degrees in closed-loop heating systems, and methanol based anti-freeze solutions in ground source heat pump loops.

DuoVent air vent assembly consists of a brass cover, air vent with silicone rubber seal, shutter, polyethylene float with valve plug, automatic vent with black cap and manual vent with red cap. Air vent assembly has a high capacity and high temperature rating and is ideal for use with glycol systems or for use as an anti-vacuum device.

Fully serviceable - can be disassembled for inspection and cleaning.
