Withstands winds up to 150 MPH

High Wind and Hurricane Zone Fans

The Greenheck Models H-G and H-GB are downblast roof exhaust fans. Applications include general clean air and light moisture exhaust. The downblast design is ideal for all applications where air is discharged directly onto the roof surface. Models H-G and H-GB have been speciﬁ cally designed for high wind and extreme weather applications. Structural bracing on the interior of the fan, tabbed and riveted curb cap corners, and high strength materials provide the added strength required to withstand winds of up to 150 MPH. Standard with a 12 inch (305 mm) tall H-GPF curb, no tie downs to the roof are required. (Other curb options are available.)

Performance: For full performance listings refer to the H-G and H-GB

Catalog.

•Air performance up to 14,000 CFM (24,000 m3/hr).

•Pressure range from 0-2.75 inches wg (0-700 Pa).

•All fan sizes are tested in our AMCA Accredited Laboratory, and all models are licensed to bear the AMCA sound and air performance seal.

Standard Construction

•Internal Bracing - High strength internal support structure and bracing.

•Shroud - Heavy gauge reinforced drawn shroud with integral rolled bead for consistent material thickness and strength.

•Drive Assembly - Motor and drive frame are isolated from the airstream and mounted on true vibration isolators, and sized for 150% of maximum driven horsepower. (No steel to steel contact)

•Bearings - Pillow block design selected for a minimum average L10 life in excess of 100,000 hours (L50 life of 500,000 hours) at maximum cataloged speed.

•Disconnect - NEMA-1 disconnect is mounted and wired from the factory.

The Greenheck Models H-CUE and H-CUBE are upblast roof exhaust fans. Applications include restaurant exhaust and mild contaminants. The upblast design is ideal for all applications where it is important to discharge air away from the roof surface. Models H-CUE and H-CUBE have been speciﬁ cally designed for high wind and extreme weather applications. Structural bracing on the interior and exterior of the fan, tabbed and riveted curb cap corners, and high strength materials provide the added strength required to withstand winds of up to 150 MPH. Standard with a 12 inch (305 mm) tall H-GPF curb, no tie downs to the roof are required. (Other curb options are available.)

Performance: For full performance listings refer to the H-CUE and

H-CUBE Catalog.

•Air performance up to 14,700 CFM (25,000 m3/hr).

•Pressure range from 0-5 inches wg (0-1,250 Pa).

•All fan sizes are tested in our AMCA Accredited Laboratory, and all models are licensed to bear the AMCA sound and air performance seal.

Standard Construction

•Internal Bracing - Additional high strength internal bracing structure.

•External Bracing - Integral high strength mounted external bracing.

•Windband - Heavy gauge one piece windband with integral rolled bead, 100% welded to an aluminum curb cap.

•Drive Assembly - Motor and drive frame are isolated from the airstream and mounted on true vibration isolators, and sized for 150% of maximum driven horsepower.

•Bearings - Bearings are pillow block design selected for a minimum average L10 life in excess of 100,000 hours (L50 life of 500,000 hours) at maximum cataloged speed.

•Disconnect - NEMA-1 disconnect is mounted and wired from the factory.

•Curb Cap - Heavy gauge with pre-punched mounting holes.
