Bell & Gossett Airtol ATF-12 Cast Iron Tank Fitting, 1/2", FNPT x FNPT 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 permit cooler liquid flow to the boiler during the off cycle as system liquid cools. Airtrol tank fittings must be used with the appropriately sized in-line airtrol or rolairtrol air separator.

Caleffi 5027 Automatic Air Vent, 1/8", MPT, 150 psi Working, 240 deg F, Brass

• Automatic air vents are designed to remove trapped air that accumulates in heating and air conditioning systems automatically
• Air removal enhances performance and life of a system by reducing the effects of corrosion due to oxygen, pockets of air trapped in the heating emitters and cavitation in the circulation pumps
• These automatic air vents eliminate residual air in heating and air conditioning systems without the need for manual intervention
• This prevents undesired noise, wear of devices in the circuits and inefficient performance of heating units
• 90 psi maximum discharge pressure
• 1.75 scfm max discharge rate
