Price RVD Series Radial Vane Diffusers are unique in design. Radial slots produce a high induction horizontal vortex of air that travels out from the face of the diffuser. The high induction vortex air pattern provides rapid mixing of the supply and room air, producing excellent uniformity of temperature in the conditioned space.

The RVD series produces the high induction horizontal vortex over a wide range of air flows, making it an ideal selection for VAV applications with high turndown ratios. The RVD provides a comfortable thermal environment with no drafts in both heating and cooling modes.

Applications for this diffuser include areas of high heat load where large quantities of cool air must be rapidly mixed with room air. This would include industrial applications with ceilings from 8 feet to 12 feet high. Other applications include areas which require high air change rates of up to 30 changes per hour. For open office environments, multiple units can be arranged in a row or more than one row.
