Type ADD

TROX swirl diffusers of the ADD type are intended primarily for supply and exhaust air control applications in the commercial sector. The diffuser face features an impressive architectural design. The form of its large discharge slots and the rear-mounted air control blades distinguish the face from conventional swirl diffusers.

The swirl diffuser is available with a round or square front panel, according to the prevailing architectural requirements. The diffuser is connected to the air duct system via a plenum box, in either vertical or horizontal configuration. Swirling, horizontal discharge of the supply air at a high induction rate guarantees swift temperature equalisation and fast reduction of the flow velocity.
