The slot diffuser VZ-41 is a linear diffuser with a system width of 41 mm, especially well suited for wall and ceiling mounting. The diffuser is available in single- and multi-slot configurations and is suited for continuous assembly. The slot diffuser consists of extruded aluminium profiles with or without side support as well as rotatably mounted, individually adjustable air guiding elements with rectifier blades and boomerang profiles. The slot diffuser VZ-41 can be used for supply as well as exhaust air (also as a combined supply and exhaust air diffuser with parallel rails) and is especially suited for constant and variable volume flows in rooms with ceiling heights of 2,30 meters to 4,00 meters. The recommended flow rate is between 50 m³/h and 150 m³/h per meter at temperature differences of +4 K to -12 K.

The VDP series’ diffusers are specialized systems with high primary induction within the plenum box as well as an actuator for various air flow geometries. The main components are the round or square box with an interior cylindrical swirl element, an adjustable control-nozzle and the rounded outlet diffuser. The swirl diffusers can only be controlled with a plenum box. Depending on the technical and architectural circumstances, the VDP is manufactured in many different formats and finishes.

The TNC/TSK is a round ceiling diffuser that consists of a ring diffuser with a spigot and an integrated, adjustable baffle plate for configuring the air flow.
