Type: Plenums For Supply / Return Ceiling Diffuser
Model :SAD-AB-1x+P; RAD-AB-1x+P
Construction: Galvanized Steel
SAD – Supply Air Diffuser (with Damper + Plenum)
RAD – Return Air Diffuser (without Damper+ Plenum)
BETEC CAD.’s Diffusers with Plenum / Neck reducers are recommended for heating, ventilating and cooling in centralized air conditioning systems.
Diffusers, with 4,3,2 or 1 way pattern deflectors for horizontal diffusion of air in their respective ways without change in air volume, pressure or sound level. 100% utilization of diffuser face area, regardless of pattern deflection, gives optimum performance in terms of air
handling characteristics. These diffusers have high diffusion induction rates, resulting in rapid temperature and velocity equalization of the mixed air mass, well above the zone of occupancy.
Correct selection and sizing of distribution plenum chambers and neck reducers is critical because terminal air resistance is very low relative to the distribution ductwork resistance. A similar effect results from use of neck reducers with circular duct connections because the
reduced duct area will cause generally higher velocities and hence increased risk of noise generation
Plenum is available with circular, square or rectangular spigots in either top or side entry applications.
