A reliable brass 1/2″ automatic air vent with check valve is essential for keeping Baxi central‑boiler systems free of trapped air. Designed for seamless integration, this vent automatically expels air bubbles that can cause noise, corrosion or reduced efficiency—no manual bleeding required.
Crafted from durable brushed brass, the unit features a 1/2 BSP male thread that snaps into place quickly and securely. A built‑in shut‑off cap lets you pause the auto‑venting function whenever maintenance or system shutdown is needed, while the integrated check valve prevents reverse flow and protects the boiler from pressure spikes.
