Automatic Brass Air Vent — Reliable, low-maintenance venting for hot-water heating systems Key benefits Keeps radiators and small heating appliances running efficiently by automatically removing trapped air. Reduces cold spots, circulation noise, and uneven heating without manual bleeding. Durable brass construction lowers replacement frequency and provides long-term reliability. How it solves problems Automatic venting continuously expels air pockets that impair heat transfer and pump performance, restoring consistent heat distribution. By preventing air buildup, it helps maintain system efficiency and reduces the need for frequent manual maintenance. What makes it stand out Solid brass body for corrosion resistance and long service life. Designed specifically for hot-water radiators and small hydronic heating devices for easy, seamless integration. Robust operating limits: handles up to 150 psi (≈10.3 bar) and temperatures up to 115 °C.
