AXP series round swirl diffusers are designed to supply air in heating, air conditioning and ventilation applications, in premises with ceilings 8.5 up to 13 feet high and with temperature differential up to 22ºF. They are suitable for multiple types of commercial buildings. Their round shape together with the helical design of their vanes cause a stable swirl diffusion of the air stream, obtaining a high induction rate and reducing the stratification. They can be mounted in drywall ceilings or directly on exposed duct.
