Construction

Surface floor diffuser (floor grille and trim ring)

-1: Deburred diffuser core
-3: Deburred diffuser core, painted black, exposed surface overtightened
-4: Deburred diffuser core, exposed surface overtigthened

Parts and characteristics

Grille insert Floor diffuser

Ring spacing: 6 mm
Height-adjustable dirt trap which serves as a reduction element for volume flow rate balancing
Adjustable swirl unit for vertical or horizontal swirling air flow or air routing

Trim ring with spring clip fixing

Rotation lock and centring grille insert
Covers the installation opening
Spring clip fixing enables different magnitude of the raised floor and the compensation of large cut-out tolerances when creating the installation openings. For the tightest possible fit of the trim ring, we recommend the minimum installation dimension
Balancing with soft flooring, e.g. carpetWorks well with soft flooring, e.g. carpet

Floor diffusers allow supply air in mechanical ventilation and air conditioning systems to flow into the room from below or from the floor. For adaptation to different local conditions, 3 different variants of the air routings are possible.

Vertical flow without adjustment option

Without adjustable swirl unit, the supply air flows vertically into the room at a moderate speed. Since cold air is heavier than warm air, the direction of flow reverses and the supply air flows back towards the floor. A low-turbulence or swell-like flow spreads over the entire floor surface. A lift current forms at heat sources such as people and equipment, so that the air is primarily exchanged in these areas.
This type of hybrid ventilation or mixed-source ventilation is designed exclusively for cooling operation. It is particularly suitable for rooms with a clear division between circulation and occupied areas. These include, for instance, cinema or theatre halls and waiting areas. The maximum supply air temperature difference should not exceed -6 K. The exhaust air should be dissipated in the upper part of the room, above the occupied zone.

Horizontal air flow

An adjustable swirl unit set for vertical flow causes a swirling vertical supply air flow into the room. In doing so, the supply air induces room air near the floor surface and quickly reduces the air velocity as well as the temperature difference between supply air and room air. This type of mixed ventilation is particularly suitable for areas that are permanently intended for people to remain. This includes, for instance, office spaces or meeting and conference rooms.

Vertical swirling air flow

An adjustable swirl blade set for vertical flow causes a swirling vertical supply air flow into the room. Through this process, the supply air induces room air. There is a rapid reduction in flow velocities and a quick reduction of the temperature difference between supply air and room air. This type of mixed ventilation results in proficient room ventilation. It is particularly suitable for areas in which people do not remain for longer periods of time. This includes corridors or similar circulation areas.
