The J&D Manufacturing Storm 55" Fiberglass Exhaust Fan is built for exceptional durability and maximum airflow in the toughest agricultural and industrial ventilation applications. Featuring a rugged aerodynamic fiberglass slant housing, a heavy-duty deep poly cone, and a hot-dip galvanized frame, the Storm is engineered for low maintenance and long-lasting reliability. Available in 1 HP, 1.5 HP, and 2 HP motor options - single or three phase - with aluminum or poly shutter configurations and cast aluminum or galvanized propeller options, the Storm delivers the flexibility to match any facility's ventilation requirements. Tool-less shutter removal and belt changing make service quick and easy, minimizing downtime in demanding production environments.
