QAL
Displacement diffuser in customized project solutions
The QAL Displacement diffuser ensures low-turbulence supply air introduction at the lowest outlet velocities for comfort and industrial applications.
- Ventilate
Customized project solution
QAL Displacement diffusers can be individually adapted for your specific project solution. Whether linear, round, semi-circular or quarter-round - we design the right diffuser for you.
Improved air quality
The operating principle of a QAL Displacement diffuser significantly improves air quality in interior spaces. The continuous rise of warmed air creates a natural suction effect that draws in fresh, unpolluted air. This process promotes both the efficient removal of pollutants to the extract air opening in the ceiling area and the continuous supply of fresh air in the immediate vicinity of people.
Model sizes
6 different nominal sizes are available in 4 different heights and many depths.
semi-circular
linear
round
quarter-round
Application areas
- for office and administration rooms, conference and meeting rooms
- cinemas and restaurants
- sports halls
- industrial and commercial spaces
- laboratories and pollutant-exposed workplaces
Low air velocities
The QAL is characterized by low air velocities that do not cause drafts. In the occupied zone, a fresh air lake is created, which is kept in constant motion by thermal effects such as machines and people, improving air quality.
The combination of improved air quality and very low air velocities makes this system an attractive alternative to conventional mixed air systems, especially for moderate cooling loads.
Removable capacity
The QAL Displacement diffuser adapts to different room uses. With a load removal capacity from 30 W/m² to 50 W/m² it covers a wide range - from quiet offices to active workshops.
This adaptability ensures optimal indoor air quality with simultaneous energy efficiency, regardless of the activity level in the room. If higher thermal loads occur, Displacement diffusers are combined with heating and cooling ceiling systems.
