Galvanized Steel Pig House Exhaust Fan

• 275 g/m² Hot-Dip Galvanized Frame: Provides corrosion resistance for humid and ammonia-rich livestock environments.
• 1270 mm Stainless Steel Blades: Large-diameter blades are designed for high-volume ventilation.
• Dynamically Balanced Impeller: Each blade assembly is balanced to improve operating stability and reduce vibration.
• Optimized Blade Angle: Professional aerodynamic blade geometry supports efficient airflow.
• Automatic Exhaust Shutters: Galvanized louvers open automatically during fan operation and help close the wall opening when the fan stops.
• 90° Shutter Opening: Automatic opening mechanism helps maintain a fully open exhaust path during operation.
• Water-Resistant Bearings: Special bearing protection helps reduce moisture ingress and supports long service life.
• Cone Fan Option: Bell-mouth exhaust cone configuration can improve airflow efficiency and reduce discharge resistance.
• Wall-Mounted Installation: Suitable for modular installation along livestock-house end walls or sidewalls.
• Climate-Control Compatible: Can be integrated with temperature controllers, staged ventilation systems or centralized environmental controls.

• Commercial pig houses
• Farrowing and breeding sow barns
• Piglet nursery houses
• Finishing and fattening pig houses
• Poultry houses and broiler farms
• Dairy and cattle barns
• Sheep and goat housing facilities
• Negative-pressure ventilation systems
• Tunnel ventilation and cooling-pad systems
• Livestock building renovation projects

• Confirm required ventilation capacity and fan quantity according to house dimensions, animal density and climate conditions.
• Prepare reinforced wall openings according to the selected fan dimensions.
• Install the fan square and level to avoid frame distortion and abnormal blade clearance.
• Seal gaps between the fan frame and wall to prevent uncontrolled air leakage.
• Check that automatic shutters open freely without obstruction.
• Verify blade rotation direction before continuous operation.
• Inspect bearings, belts, pulleys and motor components periodically according to the selected drive configuration.
• Remove dust, feathers and accumulated debris from blades and shutters to maintain airflow efficiency.
• Check blade balance and fasteners if abnormal vibration or noise develops.
• Protect electrical components during high-pressure barn washing.
• For automated farms, connect fan stages to a compatible environmental controller according to the ventilation design.

Q: What material is the fan frame made from?
A: The frame is made from hot-dip galvanized steel sheet with a listed zinc coating of approximately 275 g/m².

Q: What is the blade diameter?
A: The listed stainless steel blade diameter is approximately 1270 mm.

Q: Are the fan blades balanced?
A: Yes. The product information states that each blade assembly undergoes dynamic balancing to support smooth operation.

Q: How do the rear shutters operate?
A: The hot-dip galvanized shutters use an automatic opening mechanism and are designed to remain approximately 90° open during normal fan operation.

Q: Is an exhaust cone available?
A: Yes. A bell-mouth exhaust cone configuration is available for projects requiring optimized discharge airflow.

Q: Can the fan be used with cooling pads?
A: Yes. It can be incorporated into negative-pressure cooling systems where exhaust fans draw outdoor air through evaporative cooling pads.

Q: Can the voltage and motor be customized?
A: Yes. Motor, voltage and frequency can be selected according to project requirements and the electrical standard of the destination market.

Q: How many fans are required for a pig house?
A: Fan quantity should be calculated from building dimensions, pig numbers, required air exchange, local climate and the performance curve of the selected fan model.
