HVLS fans designed for efficiency

Blue Giant offers the AirFlow series of HVLS fans. The blade design moves cool air in summer and distributes ceiling-level heat in winter to help reduce energy bills by up to 30 percent, according to the company.

Two models are available, both of which come in a variety of blade sizes. All fans can be custom-designed for the intended application.

The six-blade Eagle VI is available in diameters from 12 to 24 ft. The compact, three-blade Falcon III features blade sizes of 6 to 14 ft.

AutoPilot is available as an option in place of the standard fan controller. This system allows tuning of individual speed adjustments, change of rotation, and multiple fans with a touch of the screen.
