VAV Systems & Diffusers

Features • Wall-mounted thermostat control • Powerful, low voltage actuator • True variable air volume (VAV) in heating and cooling modes • Maximum air volume range is from 118 to 900 CFM • Suitable for lay-in ceilings • Adjustable minimum and maximum air flows • Unitary stamped seamless backcone with removable face plate • Steel construction with baked white enamel finish • 4-way discharge pattern

The Comfort System¿ VAV Diffuser is used to vary the supply air volume from a wall-mounted thermostat. This diffuser is designed to maintain coanda effect (draft free) of discharge air along the ceiling, providing a sustained discharge velocity throughout the volume range. Operating the diffuser from an individual wall-mounted thermostat enables users to choose their own desired comfort level. The wall- mounted thermostat will give closer temperature control and eliminate the need for a step ladder to adjust the setpoint in the diffuser itself.
