Air Gaps for Reduced Pressure Zone Assemblies provide an unobstructed, physical separation between the discharge end of a potable water supply line and an open receiving vessel. The installation of an air gap and drain line are recommended on reduced pressure zone assemblies. Air Gaps can be installed vertically or horizontally.

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

Cash Acme 24644

Cash Acme VR-801 VAC uum relief valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems. It works by preventing internal VAC uum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury VAC uum. Atmosphere admitted to the system breaks the VAC uum, preventing collapse of the storage tank.,
