Design

VZ-15 is a linear slot diffuser with a profile width of only 15 mm, intended for wall or ceiling installation. The slot diffuser is designed in particular for almost invisible installation in ceilings, walls or shadow gaps.

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 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 100 mm long air deflectors, each individually adjustable.

Functionality

VZ-15 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 formation of individual air discharge during a diffuse distribution pattern results in a rapid reduction of air velocity and temperature difference, while the pressure loss and sound power level are minimally influenced by the position of the air deflectors.
