Round-neck-to-square-face construction results in 360 degree air diffusion pattern similar to a full round diffuser. High diffusion induction rates result in rapid temperature and velocity equalization of the mixed air mass well above the zone of occupancy. Horizontal performance assures confident use of cooling temperature differential of 30 degrees Farenheit and greater, at predicted low air motion 35 fpm in the zone of occupancy. DF4 Supply Diffusers perform efficiently with air loadings of 6 to 30 air changes per hour (based on 10 ft. ceiling height), and sound level range of NC 25 to 35. Core is removable to facilitate access to duct. GENERAL FEATURES Heavy-gauge all-steel construction. Ideal for VAV systems. Powder paint coating - White (other colors available upon request). Screw driver adjustment of OBD through diffuser face. One model suits both T-Bar and Drywall installations. 2" high collar available. Matching OBD dampers, baffles and plaster frames available.
