## Long description

Automatic vertical air vent Afriso PrimoVent G3/8 with Aquastop and shut-off valve R1/2 (S)A is designed to remove trapped air from heating and cooling systems. The valve operates in a vertical position and provides continuous automatic deaeration to improve system circulation and heat transfer. This model incorporates Aquastop protection to minimise water loss during maintenance and an integrated shut-off valve R1/2 (S)A that allows isolation of the vent when servicing or replacing components.
Advantages
The PrimoVent G3/8 delivers reliable automatic air release without requiring manual intervention, helping to reduce noise, cold spots and corrosion in closed circuits. Aquastop reduces the risk of accidental leakage during cap removal or maintenance tasks. The built-in shut-off valve enables quick isolation of the air vent for safe servicing and replacement while keeping the rest of the system operational.
Suitable for
Radiators and convectors in residential and commercial heating systems
Manifolds and distribution units in underfloor heating and hydronic networks
Pipework and terminal units where automatic deaeration and service isolation are required
Key specifications
Connection type: vertical G3/8 inlet with integrated shut-off valve R1/2 (S)A
Function: automatic air vent for continuous deaeration
Aquastop: built-in mechanism to prevent water escape during maintenance
Mounting orientation: vertical use only
Material and finish: corrosion-resistant materials suitable for heating and cooling systems
How to use
Install the air vent in a vertical orientation at a high point in the system or on the radiator/manifold per installation guidelines. Ensure proper sealing of the threaded connection and open the integrated shut-off valve to allow automatic venting during normal operation. When maintenance or replacement is necessary, close the shut-off valve first to isolate the unit, then use the Aquastop feature to remove the cap or service the vent with minimal water loss. After servicing, reopen the shut-off valve and check for proper operation and absence of leaks.
Usage recommendations
For optimal performance, place the PrimoVent at system high points and check periodically for correct operation. Use the integrated shut-off valve when performing maintenance to avoid draining the system. Follow system manufacturer guidelines for pressure and temperature limits and inspect for signs of wear or blockage during scheduled maintenance.
