Motor HP	Horsepower. Used to indicate a fan's motor size.
Max BHP	Brake Horsepower. A measure of power consumption. Used to determine the proper motor horsepower and wiring.
Max Fan RPM	Revolutions Per Minute. Measure of maximum fan speed.
Min Fan RPM	Revolutions Per Minute. Measure of minimum fan speed.
Ps	Static Pressure. Resistance to airflow measured in inches of water gauge.
CFM	Cubic Feet Per Minute. A measure of airflow.
Sones	A measure of loudness. One sone can be approximated as the loudness of a quiet refrigerator at a distance of 5 feet. Sones follow a linear scale, that is, 10 sones are twice as loud as 5 sones.

Model CUBE is an aluminum exhaust fan specifically designed for roof or sidewall mounted applications where contaminated or grease laden exhaust air can be discharged directly upward, away from the roof or wall surface. The fans feature a one piece windband continuously welded to curb cap and double studded isolators for true vibration isolation. Ideal for new installations or for retrofit, replacement applications. Curb adapters and reducers available to eliminate the need to field fabricate transitions when there is an existing roof curb.

Centrifugal wheel provides high-efficiency and minimal sound
One-piece aluminum windband with rolled bead provides extra rigidity
Cooling fins located on top of fan wheel draw outside air through a large breather tube directly into the motor compartment extending motor life
Windband is continually welded to the curb cap and drain trough for leakproof construction
Roof or wall mountable
Permanent embossed aluminum nameplate for exact model and serial number identification
