The Greenheck models H-CUE and H-CUBE are high wind spun aluminum
upblast powered 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 up and away from the
roof surface. Models H-CUE and H-CUBE have been specifically 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 tall H-GPF curb, no tie
downs to the roof are required. Other curb options are available from
8 to 24 inches in height. The fans have been tested in accordance with
Miami-Dade standards TAS-201/202 and are certified from clean air to
moisture laden and even grease laden exhaust.
