The Inta 15 mm Auto Air Vent is a small, self-operating valve used in heating and plumbing systems to automatically release trapped air from pipework. By letting air escape without manual intervention, it helps improve circulation and reduces noise and performance issues in the system.

Function & Purpose

In central heating and hot water systems, air can become trapped in radiators or pipe runs after filling, draining, or during operation. This trapped air can cause cold spots on radiators, gurgling noises, pump cavitation, or inefficient circulation. The auto air vent continuously bleeds this air out as it rises in the system, maintaining smoother, more efficient operation and reducing the need for manual venting.

Compatibility

The valve is designed for 15 mm pipework, which is common in domestic heating circuits feeding radiators, towel rails, and other components. It installs inline or at high points in the system where air naturally accumulates.

Design & Build Quality

The Inta auto air vent features a compact body and an internal float mechanism that opens to release air and closes to prevent water from escaping. Its simple yet effective design requires no power or manual operation once installed. The valve body is made from materials suited to the temperatures and pressures found in central heating systems.

Key Benefits

Continuous automatic air removal helps:

Maintain more efficient circulation
Reduce radiators with cold spots
Lower pump noise and cavitation
Reduce the need for manual venting

Ideal Applications

This auto air vent is ideal for installation:

At high points of the heating circuit
On radiator feed or return lines
Near manifolds or boiler flow/return runs
In pipework that frequently traps air

It’s a practical accessory for both new installations and maintenance projects, helping keep central heating systems running quietly and efficiently.
