MonsterFans Geared-Drive (GD)

Industial HVLS Fan for Warehouses

Warehouses & Industrial Applications

The GD Series fan offers diameters ranging from 8ft – 24 ft and delivers maximum speeds of
53-105 RPM. Built with a Helical Inline Reducer motor providing whisper-quiet operation for sensitive applications, and a cool 6 MPH breeze for areas up to 230 ft.

Applications

Optimal for environments with large open floor plans, high ceilings, and air that needs to move without disturbing the work below. In warehouses and distribution centers, the GD HVLS Series keeps warm air off the ceiling and circulating at floor level, reducing hot spots near loading areas.

In manufacturing facilities and airplane hangars, its whisper-quiet geared-drive motor moves air steadily across high-traffic zones without adding noise to an already loud environment.

See how our MonsterFans save energy for your heating system in the winter. When heating large buildings, heat naturally rises to the ceiling and gets wasted. With slow rotations, MonsterFans enable the warm air to start moving and spread out into the building.
