## Long description

The FLAMCO Flexvent 1/2" horizontal is an automatic air vent designed to remove trapped air from closed water heating and plumbing systems. Intended for horizontal installation, this automatic air eliminator continuously vents microbubbles and larger air pockets without manual intervention, helping to maintain efficient circulation, reduce noise and limit corrosion. The product is compatible with radiators, boilers, circulation circuits and other closed systems where a horizontal connection is required.
Advantages
The FLAMCO Flexvent operates automatically to release air reliably, which helps preserve pump performance and heat transfer efficiency. Its horizontal 1/2" connection permits installation in systems with space or orientation constraints. By preventing air accumulation, it reduces gurgling and knocking noises and lowers the risk of oxygen-induced corrosion. The unit requires no regular manual bleeding, minimizing maintenance effort and the risk of operator error.
Suitable for
Domestic and commercial central heating radiator circuits
Boiler and heat exchanger feed lines
Closed circulation loops in HVAC systems
Plumbing systems where horizontal mounting is necessary
Key specifications
Connection type: horizontal 1/2" threaded inlet
Function: automatic continuous air elimination
Application medium: water-based closed heating and plumbing systems
Installation position: horizontal
Operation: automatic, no manual venting required
How to use
Install the Flexvent unit in the designated horizontal position on a suitable branch or high point of the system where air accumulates. Ensure compatible threading and sealing materials are used to prevent leaks. After installation, bring the system to normal operating temperature and pressure; the unit will automatically vent trapped air during operation. Periodically inspect the external housing and connections for signs of leakage or damage and replace if necessary.
Usage recommendations
Install the device at system high points or on risers where air gathers; avoid mounting upside down or at steep angles. Use compatible sealing tape or gaskets on threaded joints and follow system pressure and temperature limits specified by the heating system manufacturer. If persistent air problems occur, check for system leaks, inadequate filling procedures or incorrect pump settings before replacing the air vent.
