## Summary description

Automatic air vent designed for use on an expansion (pressure-equalizing) tank in heating systems. Manufactured by DNM for Burner series, model SDNM0030. Removes trapped air to maintain system pressure stability and ensure proper circulation. Suitable for installation on domestic and light-commercial boilers and closed hydronic systems where reliable automatic air release is required.

## Long description

The DNM Burner SDNM0030 air vent is an automatic valve designed for installation on expansion or pressure-equalizing tanks in closed hydronic heating systems. It continuously expels trapped air from the tank and connected piping, helping to maintain stable system pressure and promoting reliable circulation in domestic and light-commercial boiler installations. The valve is compact and engineered for compatibility with standard expansion tank fittings, offering a maintenance-free solution for routine air removal in sealed heating circuits.
Advantages
This automatic air vent provides continuous, unattended removal of microbubbles and accumulated air, reducing the risk of noise, corrosion and flow disruption. Its design supports stable pressure balance in the expansion tank and contributes to consistent heating performance. Constructed for use in closed systems, the valve reduces the need for manual bleeding and routine intervention, which can save service time and helps preserve pump and radiator efficiency.
Suitable for
Domestic sealed hydronic heating systems
Light-commercial boiler installations
Expansion or pressure-equalizing tanks where automatic air release is required
Closed-loop heating circuits with radiators and circulating pumps
Key specifications
Function: automatic air release for expansion tanks
Application: closed hydronic heating systems and boilers
Operation: continuous automatic venting of trapped air and microbubbles
Compatibility: fits standard expansion tank connections (verify thread and size before installation)
Construction: corrosion-resistant materials suitable for heating system media
How to use
Install the air vent vertically on the designated connection of the expansion tank, ensuring the vent outlet is unobstructed and oriented upwards. Verify that the system is depressurized according to the boiler manufacturer’s instructions before fitting. After installation, repressurize the system and allow normal operation; the vent will automatically expel trapped air during circulation. Periodically inspect the external condition of the valve and surrounding fittings for leaks or damage as part of routine maintenance.
Usage recommendations
Confirm thread type and size before purchase to ensure compatibility with the expansion tank. Use the valve only in closed, pressurized hydronic systems and follow the boiler and expansion tank manufacturer’s safety guidelines during installation and service. If persistent air accumulations or system irregularities occur, consult a qualified heating technician.
