Automatic angled air vent Afriso R1/2" model 7775300 for heating and plumbing systems

Automatic angled air vent Afriso R1/2" model 7775300 for heating and plumbing systems is an automatic air eliminator designed to remove entrained air from closed heating and domestic water systems. The angled body allows installation in compact or vertical locations and the R1/2" threaded connection matches common pipe fittings. By expelling air continuously, the unit reduces the risk of airlocks, supports stable circulation and contributes to efficient operation of radiators, boilers and distribution manifolds.

Advantages

The angled construction enables flexible mounting in tight spaces and on manifolds where a straight vent would be impractical. Automatic operation vents air without the need for manual bleeding, maintaining system performance and reducing maintenance interventions. The device is compatible with standard R1/2" plumbing fittings and materials suitable for heating systems, ensuring reliable sealing and long-term operation when installed correctly.

Suitable for

• Residential and commercial radiator heating systems
• Boiler installations and heat generators
• Distribution manifolds and branch circuits in hydronic systems
• Closed domestic hot-water circulation loops

Key specifications

• Connection type: threaded R1/2" for standard pipe fittings
• Configuration: angled body for compact or vertical installation
• Function: automatic continuous air separation and discharge
• Application: closed heating and plumbing systems including radiators and manifolds
• Material compatibility: suitable for typical heating system media (water, aqueous mixtures)

How to use

Install the air vent at a high point in the circuit or on manifolds where air accumulates, using the R1/2" threaded connection. Ensure the installation orientation follows the angled design so the automatic venting mechanism can operate freely. After installation, pressurize the system and check for leaks at the connection. The device vents air automatically during normal operation; no regular manual bleeding is required, though initial commissioning checks and occasional inspection for tightness are recommended.

Usage recommendations

For reliable operation, install the vent at locations where air naturally collects and avoid installing below the fluid level or where debris may block the float mechanism. Follow manufacturer torque and sealing recommendations for threaded connections, and carry out periodic visual inspections. If the system uses aggressive additives, confirm material compatibility before installation.
