Model GB, belt drive centrifugal roof exhaust fans are designed to meet the general clean air exhaust requirements for industrial and commercial buildings. Units feature a fully rolled windband bead for increased stability and easy transport. Fresh outside air is drawn in under the motor cover to maximize motor life. 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
True vibration isolation supports the motor and wheel for long life and quiet operation
One-piece aluminum curb cap provides a weather-tight fit
Galvanized birdscreen protects the fan discharge from birds and small objects
Fully rolled windband bead for increased stability and easy transport
Positive motor cooling with fresh air results in maximum motor life
Permanent embossed aluminum nameplate for exact model and serial number identification
