The swirl diffuser type VFC/Q/DO.O4 circular or square swirl diffusers are designed to give a horizontal discharge pattern and high induction ratio, these qualities result in rapid temperature and velocity equalization and ensure confident use in cooling and/or heating in CAV or VAV applications with temperature differences up to 11°C and a high number of air changes.

Depending on architectual requirements, the swirl diffusers can be supplied with a circular or square face plate. Types VFC and VFQ are suitable for application in regular ceilings and type VFD is to be placed on a T-bar ceiling grid system. The swirl diffusers can be applied in a lowered ceiling and regular ceiling. When applied in a regular ceiling it’s recommended only to supply chilled air.
