Diffuser (thermodynamics) A diffuser is a device for reducing the velocity and increasing the static pressure of a fluid passing through a systemâ. Diffusers are used to slow the fluid's velocity while increasing its static pressure. The fluid's static pressure rise as it passes though a duct is commonly referred to as pressure recovery.
A Concentric Diffuser system is designed to eliminate the need for traditional duct-work by providing a single air diffuser to supply & return air to each rooftop. A Concentric Diffuser provides conditioned air from a HVAC rooftop unit to a space, while returning air back to the rooftop unit through the same diffuser. Designed to deliver air into an open space, or just below the ceiling of an occupied space using a very short distance.
