Overview

The flat back plenum is the box that sits behind a linear slot diffuser where it is mounted directly on a wall or other solid surface. It is made of aluminium, delivers supply air evenly to the diffuser face with minimal pressure loss, and is easy to install with the CLSD linear slot diffuser series. It is available in standard module lengths that match the linear slot diffuser configurations. The linear slot diffuser datasheet covers supply and return construction, 16 / 20 mm slot dimensions, mitered corners and air-flow data tables.
