Product information

Description

The Automatic Air Vent CALEFFI 1/2" 508041 is an automatic venting device designed to remove trapped air from heating and plumbing systems. It maintains hydraulic circulation by discharging air pockets that can reduce flow efficiency and cause noise. The device is suitable for installation on radiators, boilers, heat exchangers and closed-loop hydronic circuits where continuous, automatic air separation is required.

Advantages

This automatic air vent provides continuous, maintenance-free air removal, which helps preserve system efficiency and reduce noise. Its 1/2" threaded connection allows straightforward integration into standard piping and component ports. The internal mechanism operates automatically without external power or manual intervention, minimizing service intervals. Constructed from corrosion-resistant materials, it is compatible with typical heating system fluids and operating conditions.

Suitable for

Residential and commercial radiator systems
Boiler and heat exchanger installations
Closed-loop hydronic heating and cooling circuits
Pump and manifold air separation points

Key specifications

Connection size: 1/2" threaded connection suitable for standard plumbing fittings
Function: Automatic air separation and discharge
Compatibility: Designed for use in hot water heating and closed hydronic systems
Operation: Fully automatic float-actuated venting mechanism
Material characteristics: Corrosion-resistant body and internal components suitable for heating system fluids

How to use

Install the automatic air vent vertically on the highest practical point of the system or on designated vent ports of radiators, boilers, manifolds or heat exchangers. Ensure the 1/2" threaded connection is sealed with appropriate pipe sealant or tape and tightened to the manufacturer-recommended torque. After installation, refill and pressurize the system according to system specifications and allow the vent to operate automatically; it will expel trapped air as the fluid level reaches the internal float. Periodic visual inspection is recommended to confirm correct operation and to check for external leaks.

Usage recommendations

Use the vent on the highest points of the hydraulic circuit and replace or service it if leakage or persistent air-related symptoms occur. Avoid exposing the device to freezing conditions and follow system manufacturer instructions for pressure and fluid compatibility to ensure reliable operation.
