Manifold Auto Air Vent End Unit

An automatic air vent end unit for an underfloor heating manifold. It fits on the end of a manifold bar and lets trapped air out of the system on its own. Use it as a spare or replacement, or when building up a manifold from parts.

Why installers use it

• Lets air out on its own: no need to bleed by hand each time.
• Quieter, warmer loops: air in the system causes noise and cold spots.
• Quick swap: replace a faulty vent without changing the whole manifold.

When to use it

Fit an air vent at the high point of each manifold bar. If an existing vent drips or sticks, isolate the manifold with its ball valves before you change it.

Works with

• Manifold Pressure Gauge End Unit
• Manifold Ball Valve Set 1"
• 1" Male Manifold Blanking Plug
• All manifolds and components
