Variants Documents

  • slim design for low heat loss – ideal for installations where space is limited
  • Two-way venting principle: separated air escapes via the central hole in the float in a defined way without taking along water
  • patented float geometry for minimum capillary effect – avoids the formation of an air cushion to suppress undefined "jumps" of the float
  • Cover with patented nozzle geometry: The slot-shaped vent opening provides for a high venting capacity
  • Protective cap, cannot be lost
  • universal application for water and water-glycol mixtures (max. 50 % glycol)
  • always subjected to a 100 % function test
  • version with and without mounting valve available

For automatic venting of sealed heating systems as per EN 12828. Suitable for up to 12 bar/110 °C for water and water/glycol mixtures with up to 50 % glycol.

Automatic quick air vent with mounting valve and aqua stop. The vent cap does not have to be removed during operation of the quick air vent, not even for initial filling or servicing. Its high, narrow design is perfect in terms of appearance and function. Self-sealing connection thread.
