Air Diffuser
Category: Diffuser
Overview
Air diffusers distribute conditioned supply air into occupied spaces, promoting uniform temperature and velocity distribution while minimizing drafts and noise. The adjustable vane or fixed-pattern core controls throw direction and spread angle, allowing the airstream to mix with room air before reaching the occupied zone. Available in square, round, and linear slot configurations for flush ceiling, exposed plenum, or sidewall installation.
