112010 | Xylem | Pressure

Bell & Gossett 112010 Airtrol tank fitting ATF-12 for 12" diameter compression tanks. This fitting has a maximum pressure rating of 175 psi and a maximum temperature rating of 250°F. Airtrol Tank Fittings help establish the proper initial liquid level in the compression tank when filling the hydronic system. They help maintain proper system pressurization by directing released air to the compression tank during system operation and permitting colder liquid to flow to the boiler during the off cycle as system liquid cools.
