USE

The USE air transfer unit with integrated sound attenuation is designed for installation in drywall constructions. The product is available in a Z‑shaped or T‑shaped variant. The internal surfaces are lined with sound‑absorbing material made from melamine resin (building material class B1).

The transfer unit is available with several different diffuser faces, or without for a shadow gap installation.

USE provides an air passage between two rooms, such as an office and a hallway, when conventional duct routing is not possible, for example due to the absence of a suspended ceiling. The air transfer unit is specifically engineered to minimize the transmission of speech sound through walls.
