Product Overview

Series AS Air Separator is designed for efficient separation of air from water in Hydronic Heating Systems. Watts air separators have heavy cast iron construction.

Entrapped air in the hot water heating system piping is dispersed by the internal agitator of the air separator as the water is recalculated within the heating system piping. This provides quiet efficient operation of the hot water heating system radiation.
