Industrial Exhaust Fan With Shutter

Industrial exhaust fan with shutter is a ventilation equipment for workshop air exchange, integrating an axial fan and shutter on the same frame. When the fan runs, the shutter opens automatically and air is discharged; when the fan stops, the shutter closes automatically, preventing external air, rain, and debris from entering. It is suitable for factory workshops, warehouses, greenhouses, farms, and other places requiring ventilation or temperature regulation.

• Shutter opens and closes automatically, protection when stopped. When fan runs, shutter opens under airflow; when stopped, shutter closes automatically, blocking external air, rain, and debris. For places requiring stable indoor environment, external interference is reduced.
• Square frame structure, easy installation. Fan uses square frame design, can be directly installed on wall opening or window frame. Frame size matched to wall opening; installation requires only fixing the frame and connecting power.
• Optional speed control. Fan can be fitted with variable frequency or two-speed motor, adjusting air volume according to seasonal changes or actual ventilation demand. High air volume in summer to discharge heat; low air volume in winter to maintain basic air exchange.
• Multiple material and motor options. Frame and blade material: galvanized sheet, stainless steel, or plastic. Motor: copper winding, ball bearing configuration, adapting to different operating environments and usage frequency. Voltage/frequency configurable for target market.
• For places requiring indoor environment stability or preventing backflow, shutter type is more suitable than standard exhaust fan.

• Factory workshop ventilation
• Warehouse air circulation
• Greenhouse humidity regulation
• Farm ammonia discharge
• Garage smoke and exhaust
• Commercial kitchen exhaust

• Frame size customized to wall opening
• Blade material: galvanized sheet, stainless steel, or plastic
• Motor type and power selected to air volume requirement
• Speed control: single speed, two speed, or variable frequency
• Voltage/frequency configurable for target market
• Protection net or safety cover optional
• Brand label and packaging customizable
• OEM/ODM: customized to wall opening size and air volume requirement; customer brand on nameplate and outer packaging

After fan assembly, each unit is test-run with current and air volume recorded. Shutter opening and closing action is tested, confirming flexible opening/closing and good sealing. Blades are dynamically balanced. 100% powered test run before packing. Third-party inspection accepted. The factory has supplied this fan to workshops, warehouses, and greenhouses, and uses this field data to match blade material and motor power to ventilation demand.
