VZ-41-ZA

The VZ-41-ZA combination diffuser provides space‑saving and effective ventilation by integrating supply and extract air in a single compact product.

Designed as a linear slot diffuser with parallel rows of slots, the VZ‑41‑ZA has a profile width of 41 mm and is ideal for wall installation. The diffuser is available with 1 to 4 slots, to suit various design and air flow requirements. 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.

Engineered specifically for installation in plasterboard walls, the plenum box includes acoustic lining to ensure effective sound absorption.

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.
