Description

Automatic air vent designed to release accumulated air from high points in closed-loop heating and cooling systems. It helps reduce system noise, prevent airlocks, and maintain efficient circulation. Its vertical design allows it to be installed at the highest points where air naturally rises and collects. Manufactured from nickel-plated brass, the unit incorporates a float-controlled vent mechanism and operates without external power or routine maintenance.

Features and benefits:

  • Float-controlled automatic air release mechanism.
  • Vertical installation only – Designed for installation at system high points where air accumulates.
  • Nickel-plated brass body for long-term durability and corrosion resistance.
  • Suitable for water and water/ glycol mixtures (up to 50% glycol).
  • Robust polypropylene float designed for long service life.
  • ½” BSP male connection with slight installation gradient (max 2°).
  • No electrical or manual intervention is required during operation.
  • Supplied with a removable ½” cap to allow system pressure testing during commissioning.
