VZ-41

VZ-41 is a linear slot diffuser with a profile width of 41 mm, intended for wall or ceiling installation. The diffuser is available with 1 to 4 slots, and can be installed as single module or in a continuous linear arrangement, with active and passive diffusers without breaking the aesthetic uniformity. End pieces and end angles allow for versatile use of the slot diffuser, these can either be mounted on the right, left or both sides of the diffuser.

The diffuser is available with or without support profiles. The slot front rail is fitted with 75 mm long air deflectors featuring rectifier blades and double boomerang profiles, each individually adjustable.

VZ-41 is intended for supply or extract air and is suitable for constant or variable air flow systems. Individually adjustable air deflectors on the slot diffuser allow for easy adjustment of the distribution pattern. The air deflectors enables either a uniform air discharge or multiple smaller streams that can be directed within a 180° range. By using smaller air discharge, a rapid velocity can be achieved and a temperature reduction.

VZ-41 can be installed as a single module or in a continuous linear arrangement, with a combination of active and passive diffusers. The active slot diffusers are connected to the duct system using the plenum box AK-41.

For installation in continuous lengths, a connector is required (UPV40). For the passive diffusers a u-profile connection with M6 suspension is used (UPV40-M6).

The active slot diffusers are fastened to the plenum box using one of the following fastening methods:

• Rivets.
• Traverse drywall.
• Clip fastening (for wall installation).
