Functional description
Type VSD50 slot diffusers have adjustable air control elements. The air pattern can be adjusted to meet different local requirements. Air discharge is one-way or alternating horizontal. Heating mode with angled air discharge is also possible. The supply air to room air temperature difference may range from –10 to +10 K.
A damper blade (optional) simplifies volume flow rate balancing for commissioning.
To give rooms an aesthetic, uniform look, Type VSD50 diffusers may also be used for extract air.

Individually adjustable air control elements to meet individual local requirements
High induction results in a rapid reduction of the temperature difference and airflow velocity
Diffuser face has been optimised for maximum volume flow rate at low sound power levels
Materials and surfaces
Diffuser face made from extruded aluminium sections
Air control elements made of plastic, UL 94, V- 0, flame retardant
Diffuser face with anodised finish, E6-C-0, natural colour
Mineral wool
To EN 13501, fire rating class A1, non- combustible
Biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EG
Faced with glass fibre fabric as a protection against erosion through airflow velocities of up to 20 m/s
Technical data
Minimum volume flow rate: 20 – 40 (l/s)/m or 72 – 144 (m³/h)/m
Maximum volume flow rate with LWA ≅ 50 dB(A): 70 – 120 (l/s)/m or 252 – 432 (m³/h)/m
Supply air to room air temperature difference: –10 to +10 K
