Slot Diffusers for air distribution in HVAC systems provide excellent performance for air distribution and low pressure drops at different air passage velocities. All models of slot Diffusers are designed to give full flexibility in volume and air pattern control. Air distribution pattern can be made horizontal along the ceiling. Deflecting vanes and opposed volume damper can be adjusted from the diffuser face. By adjusting the volume damper, flow volume can be adjusted. The volume damper is designed in a unique way that it can be used as an equalizing grid. The Diffusers are constructed from high quality aluminum extruded profiles.
