Application

Types PHT..O4 and PHW..O4 laminar “down-flow” diffusers are designed to have a minimum aspiration and give a vertical discharge for applications where clean air control is especially important. These diffusers with their “piston effect” air pattern use the (ﬁltered) supply air to create a protective clean air curtain around the working area. Typical applications are hospital operating rooms, X-ray rooms, intensive care rooms, pharmaceutical laboratories, chip factories and all other kinds of clean rooms. Laminar “Down-flow” diffusers may also be speciﬁed in situations where the air change requirements exceed the capabilities of other diffusers.
