This guide is for homeowners and heating engineers seeking to efficiently remove air from heating systems. The Altecnic 502530 Robocal automatic air vent valve offers an easy-to-install solution for continuous air bleeding, ensuring optimal system performance. A key consideration is its specific connection size and pressure rating, which must match system requirements.

Its primary function is to automatically and continuously release trapped air from heating systems, improving efficiency and preventing common issues like cold radiators and system noise.
The air vent features a 3/8" male connection.
The discharge pressure rating is 4 Bar, meaning it is suitable for systems operating up to this pressure.
It is recommended to perform a visual check periodically, perhaps annually, to ensure it is free from blockages and functioning correctly.
Automatic air vents are typically designed for vertical installation to function most effectively with rising air. Consult the manufacturer's specific guidelines if considering alternative orientations.
The check valve prevents water from flowing back into the vent when it is not actively discharging air, maintaining system water levels and preventing minor leaks.
The product is manufactured by Caleffi and distributed by Altecnic.
Ensure the system pressure does not exceed 4 Bar. Check that the check valve is functioning correctly; if not, the unit may need replacement.
Verify the vent is installed at the highest point and is not blocked. Ensure the connection is secure and the vent is oriented correctly. Check for other potential air ingress points in the system.
Check for any obstructions within the vent's mechanism. The system might not have enough air pressure for the vent to activate, or the vent may be faulty and require replacement.
Setup: The Robocal is installed vertically in the highest accessible point of the heating system where air is likely to accumulate. Ensure the system is isolated and drained to a safe level before installation. Screw the 3/8" male connection into a suitable fitting. Once installed, slowly reintroduce water to the system and check for leaks around the connection. The vent will automatically begin its air-bleeding function as the system heats up.
Compatibility: This air vent is compatible with standard heating systems that operate below a pressure of 4 Bar and have a fitting that accepts a 3/8" male thread. It is suitable for central heating systems, hot water systems, and solar thermal installations.
Care: Periodically check the vent to ensure it is not blocked by debris or limescale. While automatic, manual inspection (e.g., annually) is recommended. If you notice a persistent air issue or water discharge, the vent may require cleaning or replacement.
