Product Information -

Designed to provide an even 2-way horizontal flow along the length of your workspace, this prism-shaped perforated diffuser is ideal for cleanroom and lab applications where a high capacity flow is demanded. Available in steel, stainless steel and aluminum construction, the PHC is supplied in modular lengths with joiner mullions to suit your specific applications. A special internal deflector grid (aluminum in all three designs) generates an even horizontal airflow through the perforated diffuser face. Available in two standard duct widths, the PHC has superior capacity to that of a similar size slot diffuser. Like all Price special environment diffusers, the PHC can be disassembled for thorough cleaning.
