Low Discharge Velocity

With increased air dispersion surface area, D-Series Diffuser models feature lower average discharge velocity when compared to flat faced metal diffusers. At 750 CFM, a 24”x48” All-Fabric D-Series Diffusers offer 63 ft/min average discharge velocity, lower than the 107 ft/min average of metal. 

Surround Flow D-Series Diffusers produce a uniform and radically diverging air flow pattern, providing.

  • Less Airflow Turbulence
  • Lower Average Discharge 
  • Lower Terminal Velocity
  • Lower Noise
