3 Cone Diffusers

3 Cone Supply Diffusers with integral round necks are recommended for heating, ventilating and cooling. 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.

  • GENERAL FEATURES
  • Ideal for VAV systems.
  • Powder coating – White (other colors available on request).
  • One model suits both T-Bar and Drywall installations.
  • Adjust the OBD screwdriver by the face of the diffuser.
  • 2″ high collar available.
  • Matching OBD dampers, baffles and plaster frames available.
