Product information

Description

Perfexim Automatic Air Vent MINI 3/8 (model 9003+S) with G3/8 connection and PN10 pressure rating is a compact automatic vent designed to expel trapped air from closed heating and plumbing systems. The device supports continuous air removal without manual intervention, helping to maintain hydraulic balance, reduce noise and prevent corrosion in radiators, boilers, manifolds and pipework where a G3/8 port and PN10 compatibility are required.

Advantages

The compact design of the Perfexim MINI 3/8 enables installation in confined spaces and on various system components. Its automatic operation removes the need for frequent manual bleeding, contributing to more stable system performance and lower maintenance effort. The G3/8 threaded connection and PN10 pressure rating make the vent compatible with common residential and light commercial heating systems. Materials and construction are selected for reliable sealing and long service life under normal operating conditions.

Suitable for

  • Bleeding radiators and convectors in closed heating systems
  • Automatic venting on boilers and hot-water heaters
  • Air removal on manifolds and distribution headers
  • Installation on vertical and horizontal pipework with G3/8 ports

Key specifications

  • Connection: G3/8 threaded port
  • Pressure rating: PN10 (suitable for systems up to nominal 10 bar)
  • Function: automatic air release for closed systems
  • Size/form factor: compact inline vent designed for limited space
  • Typical applications: heating circuits, boilers, manifolds, radiator connections

How to use

Install the automatic air vent upright into a G3/8 threaded port on the radiator, manifold, boiler or pipe fitting according to the system layout, ensuring that the device remains in a vertical position for correct operation. Before installation, isolate the section of the system, depressurize and drain if necessary to avoid leaks. Hand-tighten and then apply appropriate sealing tape or joint compound to the threaded connection as recommended for the system. After installation, repressurize the system and check for leaks; the vent will automatically release entrained air during normal operation.

Usage recommendations

Position the vent at a high point or air-collecting location in the circuit and keep the device accessible for periodic inspection. Avoid placing the vent in continuously flooded or submerged locations. If the system includes water treatment or aggressive fluids, verify material compatibility and perform routine checks for proper operation.
