Parts and characteristics

Diffuser core

Ring spacing 6 mm
Height-adjustable dirt trap serves as a damper element for volume flow rate balancing
Adjustable swirl unit for swirling airflow in vertical or horizontal flow direction

Clamping flange with clamp spring attachment

Anti-twist device for the grille insert
Covers the installation opening
Clamp spring attachment 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 clamping flange, we recommend the minimum installation dimension
Levelling of 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 swirling airflow

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 example, office spaces or assembly and
meeting rooms.

Vertical swirling airflow

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.
