Maximum flexibility
No cabling necessary

The mechanically automatic volume flow controllers VRW are used to control a constant volume flow in round air ducts of Comfort Air Technology systems independently of the pre-pressure.

Constant volume flow controller in round design, mechanically self-acting (no external energy required), insensitive to soiling.

  • Volume flow control without external energy – no wiring required
  • Maximum flexibility – freely adjustable volume flows
  • Insensitive to dust or environmental influences – maintenance-free with reliably precise control
  • Cost-effective
