Air Flow & Cooling Efficiency

Air supply ducts block ceiling space

(return path)

resulting in inefficient energy control

Pressure Difference between Rooms

Makes door operation difficult

Air Volume Control

Large Control Variation of the

conventional dampers makes Air

volume control inefficient

Diffuser Balancing

Not possible when independent
