Installation Manual
For maximum efficiency use the Nextek Power Systems Speed Control in conjunction with the
Vari-Cyclone DC Powered Ceiling Fans. The Speed Control makes clockwise and counter-
clockwise rotation possible.
The Vari-Cyclone is powered by a permanent magnet, TENV (totally enclosed non-ventilated) 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 3-

floor in an open room. At 24 VDC the 3-blade fan will run at approximately 138 rpm, moving 3,925 CFM
when mounted at least 8 feet above the floor in an open room.
