The Vari-Fan DC Powered Ceiling Fan is the perfect choice for a variety of
indoor/outdoor applications, including homes, enclosed porches, greenhouses,
warehouses, offices, schools, and cabins. Everything you need to assemble and mount a 4- or 5-blade Vari-Fan comes right in the box.

The Vari-Fan is powered by a permanent magnet, TENV (totally enclosed nonventilated) motor with long-life brushes. The motor draws 0.5 amps at 12 VDC and 0.78 amps at 24 VDC. At 12 VDC the 5-blade fan will run at approximately 60 rpm, moving 1,500 CFM when mounted at least 8 feet above the floor in an open room. At 24 VDC the 5-blade fan will run at approximately 120 rpm, moving 2,700 CFM when mounted at least 8 feet above the floor in an open room.

For maximum efficiency use the Nextek Power Systems Speed Control in conjunction
with the Vari-Fan DC Powered Ceiling Fans. The Speed Control makes clockwise and
counter-clockwise rotation possible.
