The RTBD is a flower-shaped swirl diffuser, type: surface-mounted. The swirl technology creates an extremely stable supply-air pattern. The diffuser is suitable for large air volumes with extremely large temperature differences in respect of the room.

The smaller versions of the RTBD can be supplied as a poured concrete diffuser.

Most important features:

  • Suitable for heat-pump systems (VRV/VRF) with extremely low supply-air temperatures
  • Suitable for low rooms
  • Highly inductive

The RRBD is the return version and is the same as the RTBD in appearance.

Swirl diffusers are extremely suitable for variable volume systems.
