Description
Product Description
The SD series slot diffusers are engineered to uphold superior air diffusion in occupied spaces, ensuring optimal air quality. Versatile in function, they can be employed for supply, return, and exhaust air applications. In supply air systems, the air pattern can be adjusted by rotating the air deflectors in either direction.
Adjustable Air Deflectors
Two air deflectors per slot set horizontal or vertical diffusion pattern — rotatable in either direction for supply air applications.
Hit-and-Miss Damper
Volume control via hit-and-miss damper on top side — two aluminium profiles with evenly spaced rectangular openings; top profile adjustable.
Equalizing Grid
Single extruded aluminium profile with equally spaced openings affixed to top side — ensures even air distribution across discharge face.
Slot Width Options
3/4" (20mm) or 1" (25mm) slot widths — 1 to 6 slot configurations available per model.
Plenum Box Options
K-110 plenum with built-in balancing damper (side or top entry) or VK-140 plenum without balancing damper — galvanized steel Ga.24 with 25mm acoustic lining.
