From our used equipment inventory. We have two 20 horsepower electric fans. These are motion picture standard variable speed fans for studio and on location use. They are 3 phase 220VAC wash down grade motors. The controllers were just replaced with Nema 5 housing Banshaw motor controllers. You can also plug in the remotes and run these from a manual remote (currently standard operating mode). The plug ends are cam lock with 3 hots and one ground (NO Neutral). The blades are 5 vane CFRP. These are really great units and a huge value in any effects kit. Please contact directly at email@example.com or 403-236-0025.
