## Summary description

Automatic lateral air vent FERRO O15ASB with 1/2" connection is designed to remove trapped air from heating and cooling installations. The compact lateral design mounts on radiators, manifolds or pipe runs to release air automatically and maintain system efficiency. Suitable for central heating, underfloor heating and chilled water circuits where automatic bleeding is required.

## Long description

The Automatic lateral air vent FERRO O15ASB 1/2" for heating and cooling systems is a compact automatic air eliminator intended to extract trapped air from closed HVAC circuits. Its lateral configuration allows installation on radiators, manifolds, headers or horizontal/vertical pipe runs where a 1/2" threaded connection is used. By continuously releasing accumulated air, the valve helps maintain hydraulic efficiency, reduce noise and support stable circulation in central heating, underfloor heating and chilled water systems.
Advantages
The FERRO lateral air vent provides automatic, continuous venting without manual intervention, reducing the need for routine bleeding. Its compact lateral body enables installation in confined spaces beside radiators or on manifold ports. The device is compatible with common hydronic systems and is designed to operate reliably under typical heating and cooling temperatures and pressures. Simple threaded connection ensures fast fitting and replacement when necessary.
Suitable for
 Central heating radiators and convectors
 Underfloor heating manifolds and circuits
 Chilled water distribution and fan coil units
 Manifolds, headers and pipe runs requiring automatic air elimination
Key specifications
 Connection size: 1/2" threaded lateral connection
 Function: automatic air bleeding/venting
 Mounting orientation: lateral installation on radiator, manifold or pipe
 Typical application: closed heating and cooling systems (hydronic circuits)
 Construction: compact body suitable for confined installation spaces
How to use
Install the air vent on a compatible 1/2" threaded port in the system at a high point where air tends to collect. Ensure the system is depressurized and drained locally before fitting. Screw the valve in securely using appropriate sealing material on the thread, and orient the lateral body as required for clearance. After installation, slowly repressurize the system and check the vent for proper operation; the valve will automatically discharge trapped air during normal operation. Periodically inspect for leaks and ensure the vent cap remains free of debris.
Usage recommendations
Choose a location at or near the highest point of the radiator, manifold or pipe section to maximize automatic air removal. For systems with frequent air ingress, combine this vent with manual bleeds or additional automatic vents at other high points. Follow system pressure and temperature limits and perform visual checks during initial commissioning and regular maintenance intervals.
