J&D Manufacturing Storm Torque Exhaust Fan, 55 Inch - 27,986 CFM - Poly Shutter – 27,986 CFM

The J&D Manufacturing 55" Storm Torque Exhaust Fan is engineered for maximum airflow and long-term reliability in large-scale barn and greenhouse ventilation systems. Built with a rugged aerodynamic fiberglass housing and a high-efficiency 2 HP totally enclosed torque-drive motor, this fan eliminates the energy losses and maintenance headaches of belt-and-pulley systems €” delivering consistent, powerful airflow shift after shift. Fully VFD-compatible and available with aluminum or poly shutters, the Storm Torque is the go-to choice for high-volume ventilation in dairy, poultry, swine, greenhouse, and industrial facilities. Features & Benefits Aerodynamic Fiberglass Housing: Durable, corrosion-resistant fiberglass construction with a heavy-duty deep poly cone delivers superior performance and long service life in harsh agricultural environments. High-Efficiency 2 HP Totally Enclosed Motor: Torque-drive design eliminates belt-and-pulley efficiency losses, maintaining consistent airflow output over the life of the fan. VFD Compatible & Recommended: Full Variable Frequency Drive compatibility enables precise speed control, significant energy savings, reduced motor wear, and extended operational life. Choice of Aluminum or Poly Shutters: Select aluminum shutters for lightweight durability or poly shutters for added corrosion resistance €” both designed for reliable open/close performance. Drainage Holes in Housing: Strategically placed drainage holes prevent water and ice buildup inside the housing, maintaining performance in cold or wet environments. Slanted Design: Housing is slanted to minimize moisture and debris collection, reducing maintenance requirements and prolonging fan life. Smooth & Quiet Operation: Torque-drive motor and galvanized propeller deliver high-volume airflow €” up to 31,971 CFM €” with minimal noise, suitable for livestock and light-sensitive plant environments. Broad Application Range: Designed for dairy, poultry, swine, greenhouse, and industrial ventilation where high-volume, dependable exhaust is critical.
