Ceiling- and Swirl Diffusers

The diffusers type RA are air feed elements with blades arranged at a tangent to promote air flow. They are suitable for fitting within false ceilings. Their excellent flow properties are retained when used as free-blowing air feed elements. The high secondary air induction rate also makes the air swirl diffusers suitable for systems supplying air at a variable rate (25 to 100%) and in assembly areas where a high degree of comfort is very important.

The ceiling diffusers circular and square are suitable for the introduction of supply air or the removal of extract air in the ceiling.
They are available with circular or square exterior frames.
The two designs, flat (type F) and conical (type K), differ - above all - in their free cross-section. They blow the air flat along the ceiling and therefore can be employed as well for rooms with a low height.

The linear ceiling diffusers with one or two-sided discharge are especially suitable for air supply through ceilings. They distribute the air along the ceiling and can be used in very low rooms.
The linear ceiling diffusers feature excellent induction. Mixing of the air jets with the room air and thus the heat exchange begin in the immediate neighbourhood of the diffuser. Therefore, warmer and particularly colder air can be supplied without draft effects.
