Air diffuser BLQ

Overview
The BLQ step diffuser provides effective ventilation for large rooms and is particularly suitable for cinemas, theaters and concert halls.

Application & Installation
Designed for installation in a pressure floor. Air intake can be arranged, for example, below the window front via a strip-type air box. The diffuser can be used with low cooling loads or combined with static cooling surfaces to supply the required conditioned fresh air volume flow.

Key features

• Even air distribution without draughts at high temperature differences
• Discreet appearance due to stepped recessed installation, integrating with existing architecture
• Individual colour design possible in all colour systems (e.g., RAL, Pantone); special designs such as stainless steel on request
• Low-turbulence displacement airflow with long jet penetration

Design / Options
Optionally available with a throttle element. Custom colors and special materials available on request.
