industrial solar fan, warehouse ventilation, factory exhaust, roof mounted fan, adjustable solar panel, brushless DC, high CFM, heavy duty

This heavy-duty solar industrial roof exhaust fan pulls hot, fume-laden air out of warehouses, factories, workshops and steel buildings during the day, cutting roof temperatures by 10–18°C and reducing HVAC load. The large adjustable-tilt monocrystalline panel powers a brushless DC direct-drive motor — no belts to slip, no bearings to grease, no filters to replace. Galvanized steel housing and stainless steel blades stand up to industrial dust, oil mist and weather. Mount it on the roof, switch it on, and let the sun ventilate your building for free. Ideal for EPC projects, retrofit jobs, steel structure buildings and container stations where wiring costs are high.
