TROX slot diffusers type VSD35 are available in 1- to 4-slot configuration. The diffuser face consists of a one-piece extruded element, irrespective of the number of slots, thus avoiding any visible seams.

The type VSD35  is suitable for installation in rooms of heights ranging from approx. 2.60 m to 4.00 m. The low overall height of these slot diffusers makes them suitable for low ceiling cavities and, in particular, for installation in suspended roof systems. They offer high induction, resulting in swift reduction of the supply air temperature differential and the air discharge velocity. The recommended supply air temperature differential stands at ±10 K. The stable discharge behaviour type VSD35 slot diffusers makes them suitable for use in systems with constant or variable volume flow. The air discharge direction can be adapted as necessary to the desired room conditions.

Slot diffusers type VSD35 are supplied with rear-mounted plenum box, whereby the air duct system is connected via the side-mounted round spigot.
