Webstone’s vertically mounted air separator can be conveniently placed beneath a wall-hung boiler, upright in the system supply line. It is available in ¾” or 1” with MIP, FIP, sweat or press connections. Isolation accessories include full port ball valves and Isolator uni-flanged ball valves. The G1 union connections simplify installation and prepare the air separator for future service. Install a G1 dual temperature gauge and verify boiler output right at the source.
