## Summary description

Automatic air vent FLAMCO FlexVent R 1/2" angled in white, model 27711. Designed to automatically remove trapped air from heating and plumbing systems, this 1/2" angled vent helps maintain circulation efficiency and reduces noise and corrosion.

## Long description

The FLAMCO FlexVent R 1/2" angled automatic air vent in white (model 27711) is a compact device engineered to remove trapped air from closed heating and plumbing systems. Installed at high points of radiators, boilers or piping circuits, this automatic vent continuously expels microbubbles and larger air pockets to preserve system circulation, reduce noise and limit corrosion. The angled body and 1/2" connection simplify mounting in tight spaces and help ensure reliable operation in hydronic systems where automatic air elimination is required.
Advantages
The angled design offers flexible installation options when vertical space is limited, while the automatic float mechanism provides continuous air discharge without manual intervention. The white finish integrates with most heating equipment and radiator valves. By maintaining efficient fluid flow and minimising trapped air, the vent contributes to steady heat transfer and quieter system operation.
Suitable for
Domestic and commercial radiators
Boilers and heat exchangers in closed hydronic systems
Piping circuits with elevated air accumulation points
Replacement or retrofit of manual air vents
Key specifications
Connection size: 1/2" angled
Function: automatic air separation and discharge
Mounting orientation: angled fitting for compact installations
Finish: white
Typical applications: closed-loop heating and plumbing systems
How to use
Install the vent at the system's high points where air accumulates, using the 1/2" angled connection and appropriate sealing materials. Ensure the vent is accessible for periodic inspection and that installation follows system pressure and temperature limits. Once installed, the internal float and valve mechanism will automatically open to release accumulated air and close to prevent water loss. No routine manual bleeding is required, though occasional checks for proper operation are recommended.
Recommendations for use
To maximise performance, fit the vent in an accessible location and combine it with proper system deaeration practices such as flushing and filtration. Verify compatibility with system pressure and water chemistry to reduce the risk of blockage or corrosion of moving parts.
