How the PD / PE works.

A ceiling outlet with a HEPA filter that supplies the air turbulently, so that contaminants in the room are diluted.

The Puridrall (PD) supplies filtered air through a star-shaped swirl element. The matching Puri-inlet (PE) filters the return air through a perforated face plate. You change the filter from above or from below, and you connect the plenum box on top or on the side. According to the brochure, the technical specifications are in data sheet DS 4087.

Applications: cleanrooms with turbulent mixing ventilation (p. 37). Peek also offers the Puridrall for laboratory rooms, next to the LAB-V.
