The proprietary plenum boxes for our SDVP vane swirl diffusers are designed to guarantee a good mixing of the air prior to diffusion through the terminals. Available with Side or Top Entry connections to customer-specific diameter, 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.
The Supply air plenum box includes an internal baffle plate to evenly distribute the airflow over the swirl area.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Waterloo Air Products plc is consulted before specifying.
