Diffuser

The Step Down Diffuser is an alternative to the Slab Grill used in Soffit Discharge exhaust applications. The sleek design not only finishes the termination of the duct but also redirects and softens the experience of air flow. This component is often used when terminating exhaust through balcony ceilings.
