J&D Manufacturing 72" Mega Torque Exhaust Fan with Pre-Wired VFD – 480V

The J&D Manufacturing 72" Mega Torque Exhaust Fan with Pre-Wired VFD combines the maintenance-free reliability of torque-drive technology with the convenience of a factory pre-wired and pre-set Variable Frequency Drive. Available wired for 240V or 480V, each unit ships ready to install with a NEMA 4x-enclosed VFD mounted in the airstream for low operating temperatures, pre-installed EMC filters, and a soft-start function to reduce power surges and extend fan life. The result is a high-efficiency, variable-speed barn exhaust fan that lowers energy costs, minimizes maintenance, and delivers up to 46,162 CFM at 0" static pressure. Features & Benefits Pre-Wired, Pre-Set VFD Included: Factory-wired to the motor and pre-configured for easy installation - no VFD programming or separate wiring required. NEMA 4x VFD Enclosure: Cooling fins mounted in the airflow keep the VFD at low operating temperatures, extending drive life in demanding environments. Short Motor-to-VFD Wire Length: Minimizes electrical noise and extends motor life by reducing voltage spikes between the drive and motor. Pre-Installed EMC Filters: Eliminates interference with RFID readers and other farm electronics commonly used in modern dairy and poultry facilities. Soft Start: Gradual motor ramp-up reduces startup loads and extends fan life. No Belts or Pulleys: Torque-drive design eliminates drivetrain maintenance - no belts to change, no pulleys, no bearings to lubricate, no greasing. Available in 240V or 480V: Choose the configuration that matches your facility's electrical infrastructure. 5-Blade Aluminum Propeller: Innovative 5-blade aluminum prop with one-piece molded cone and heavy-duty galvanized guard. Heavy-Gauge Stainless Steel Shutter Clips: Corrosion-resistant clips for long-lasting shutter retention. UV-Resistant Fiberglass Housing & Cone: Smooth molded exterior resists UV degradation and is easy to clean.
