Diffusers are used to recover static pressure and deliver uniform airflows in installations for comfort and industrial ventilation.

These basic diffusers are designed to slow down high velocity flows at a uniform velocity profile, resulting in a recovery of (static) pressure. These diffusors provide a smooth airflow, reduce pressure loss and are available in short, long, extra long or double lengths.
