The KNF diffuser supply / extraction presents an integrated solution for environments in which there is a significant change of air.
It incorporates in a single product supply, with a peripheral structure of four ways diffuser, and the extraction of air through the perforated central panel. the horizontal air throw from the slots creates a suction effect toward the panel perforated central facilitating the exchange of air, and avoiding the risk of short-circuiting of the supply directly in extraction.
