Removing free air from the system prevents component damage and system failure, reducing downtime and maintenance costs. The SpiroTop air vents are available for pressures up to 25 bar and temperatures up to 200 °C.


Benefits of the SpiroTop fully automatic air vent:

  • Special valve construction ensures valve is closed completely
  • Long lasting valve seat
  • Solid plastic, robust floats which cannot rupture
  • Large air gap between the valve and the water (at least 40 mm) prevents valve contamination and leaks
  • 1/2" connection prevents pipette effect
  • Available in stainless steel
  • Also for high temperature and/or high-pressure system environments (a.o. Solar systems)

The positioning of the SpiroTop

Free air in a heating or cooling system always raises to the highest point in the installation (components). Therefore, the SpiroTop air vents always need to be installed at the highest point in the installation.
