Displacement flow diffuser for step installation BLQ

Without draughts
Low-turbulence displacement air flow

The BLQ step diffuser guarantees effective ventilation of large rooms and is therefore particularly suitable for cinemas, theaters or concert halls.

This type of air outlet has proven its worth and has often been chosen in conjunction with air outlets integrated into steps, e.g. underneath theater or concert seating.
Designed for installation on a pressure floor.
Air intake e.g. below the window front via an air box designed as a strip element. It can be used, for example, with low cooling loads or in conjunction with static cooling surfaces to supply the hygienically required and conditioned fresh air volume flow.

  • Even air distribution without draughts at high temperature differences
  • Discreet: thanks to its stepped installation, the diffuser blends harmoniously into the existing architecture
  • Color design individually according to customer requirements in all color systems possible: for example RAL, Pantone and many more. Special designs (e.g. stainless steel) on request
  • Low-turbulence displacement air flow, large jet penetration depth
