• Low Noise Running State: Permanently lubricated motor runs smoothly without extra maintenance. Optimized structure cuts noise greatly, so it can run quietly even at full speed inside quiet rooms.
• Sturdy All Metal Build: Galvanized steel frame, aluminum shutters and steel fan blades ensure large air output. The reinforced motor lasts longer and avoids deformation during delivery.
• Self Closing Automatic Shutter: Aluminum shutters open while working and seal fully after shutdown, blocking dust and rain. It lowers heat loss and noise for year-round use in basements and warehouses.
