PBHLB Plenum Box to suit CSB Barrel Slot Diffusers

The proprietary plenum boxes for our Barrel Slot Diffusers are designed to guarantee a good distribution of the air prior to diffusion through the terminals. Available with Side or Top Entry connections to customer-specific diameter/shape, these can be fitted with Spigot flap dampers FD, cord- or quadrant-operated, as well as 6mm acoustic lining (optional) reaction to fire class
C-s3-d0 to EN 13501-1: 2007 to avoid noise generation.

An internal baffle plate is fitted as standard to the plenum box to help evenly distribute the airflow over the whole slot length. Also available with rivet fix (hem fix as standard).
