Product details
The swirl diffuser DT has progressively twisted blade profiles and ensures perfect jet control in every situation with constant and variable volume flows.
Function
Even in cooling mode, this ceiling diffuser ensures reliable application of the supply air flow to the room ceiling. It is suitable for supply air and extract air applications with variable and constant volume flows.
The product enables high volume flows with low sound power levels. The radial and axially symmetrical design of the front plate ensures perfect room flow.
Symmetrical air distribution is achieved via a square or round front plate with an attractive design.
DT swirl diffusers create a high induction of the room air directly at the diffuser. This very quickly reduces the velocity of the outgoing supply air and the temperature differences.
Design
DT swirl diffusers are made of galvanized sheet steel and are supplied powder-coated. Plenum boxes made of galvanized sheet steel are available to match the DT swirl diffuser.
A version optimized for low installation heights is available. With the optional damper, the volume flow can be conveniently adjusted without dismantling the swirl diffuser.
The matching plenum boxes are measured together with the ceiling air diffuser and always form a balanced unit for maximum comfort.
Dimensions of swirl diffuser DT
They are available in nominal sizes from 325 mm to 625 mm and with a hole pattern from 325 mm to 600 mm.
Product markings
The DT swirl diffusers are marked with a hygiene certificate from an independent external testing institute.
