Chore-Time's direct-drive Endura fans feature no belts, pulleys or bearings for low maintenance. Variable speed functionality allows growers to achieve further energy savings by slowing the fan whenever the air flow requirements allow. Fan speed is controlled automatically by a CHORE-TRONICS 3 controller, in combination with a variable frequency drive. HYFLO shutters improve fan performance by minimizing obstructions during operation and a cable attachment helps maximize efficiency by allowing the HYFLO doors to float left or right together, the company says.
