Automatic Air Vent CALEFFI Aercal 1" right-hand, model 507611

The Automatic Air Vent CALEFFI Aercal 1" right-hand, model 507611 is designed to continuously remove trapped air from hydronic heating and plumbing circuits. With a 1-inch inline connection and right-hand orientation, this air vent is intended for installation on radiators, distribution manifolds or pipe runs where automatic, maintenance-free deaeration is required. The device maintains system efficiency by preventing air locks, improving water circulation and reducing noise caused by trapped air.

Advantages

The CALEFFI Aercal automatic vent operates without manual intervention and provides constant automatic deaeration to keep systems running smoothly. Its compact inline form factor and right-hand connection orientation simplify installation in confined spaces or on pre-arranged plumbing layouts. The design reduces the need for frequent manual bleeding, limits the risk of corrosion caused by air accumulation, and helps maintain consistent heat transfer and system performance.

Suitable for

• Hydronic heating radiators and convectors
• Heating and cooling distribution manifolds
• Domestic hot water and closed circulating pipework
• Boiler secondary circuits and pump groups

Key specifications

• Connection type: inline 1-inch thread, right-hand orientation
• Function: automatic air removal (automatic venting)
• Suitable medium: water and water-based heat transfer fluids in closed systems
• Installation position: inline on radiator, manifold or pipework with right-hand connection
• Operation: maintenance-free automatic operation under normal system pressure

How to use

Install the automatic air vent in the intended position with the 1" right-hand threaded connection, ensuring correct orientation and secure sealing to the mating fitting. After installation, fill and pressurize the system according to the system manufacturer's procedures. The vent will automatically discharge trapped air as the system operates; no regular manual bleeding is required. Periodically inspect the vent for leaks and proper seating, especially after initial commissioning or system maintenance.

Usage recommendations

Use the CALEFFI Aercal air vent in accessible locations to allow visual inspection and occasional maintenance checks. Ensure compatibility with system pressures and fluids, and follow local codes and system manufacturer guidelines when integrating the vent into hydronic installations.
