Function linear diffuser INDUL:

The supply air is divided into fine individual jets which distribute the supply air into the room at an angle of 45° alternately to the left and to the right. The result is an especially uniform air distribution with an optimal diffuse ambient air flow, and no noticeable draughts.

System advantages

  • Completely draught-free air distribution
  • Low diffuser widths, from 15 mm
  • Unobtrusive installation in ceiling joints
  • Temperature differences up to -14 K
  • Light, clean ceilings due to fine-jet characteristics
  • Simple, quick and clean installation in all ceiling systems
