Self-Balancing Pig House Air Inlet

• Multi-flap self-balancing inlet structure
• Automatic opening under negative pressure
• Grouped wall or corridor installation
• Sensitive and flexible flap movement
• Suitable for high summer ventilation demand
• Designed for integration with livestock exhaust systems

• Self-Balancing Operation: The inlet flaps respond to pressure differences generated by the ventilation system for automatic opening and closing movement.
• Negative Pressure Activated: Exhaust fans create the pressure differential required to draw fresh air through the inlet.
• Secondary Summer Air Intake: Particularly suitable for pig-house corridor systems that require additional inlet capacity during warm weather.
• Multi-Flap Design: Several horizontal inlet panels provide a large effective opening area within a compact wall installation.
• Fast Response: Flexible flap movement allows the inlet opening to respond quickly as ventilation demand changes.
• No Dedicated Actuator Required: Normal opening can be driven directly by negative pressure instead of a separate electric inlet actuator.
• Modular Installation: Multiple inlet sections can be arranged according to building layout and required ventilation capacity.
• Climate System Integration: Works with exhaust fans, cooling pads and environmental control equipment in mechanically ventilated livestock houses.

• Pig house corridor secondary air intake
• Summer pig house ventilation
• Farrowing house ventilation systems
• Nursery pig house ventilation
• Growing and finishing pig houses
• Negative pressure livestock buildings
• Exhaust fan ventilation systems
• Cooling pad and tunnel ventilation projects
• New farm construction and ventilation renovation projects

• Determine inlet quantity and opening area according to exhaust fan capacity and the livestock-house ventilation design.
• Install the inlet frame level and square so that all flap panels can move freely.
• Seal gaps between the inlet frame and building structure to reduce uncontrolled air leakage.
• Keep sufficient clearance around each flap to prevent interference during opening and closing.
• Check that all flap panels respond smoothly when exhaust fans create negative pressure.
• Clean accumulated dust, cobwebs and debris from the inlet surfaces periodically.
• Inspect hinges, pivots, balance components and fasteners regularly for wear or looseness.
• Verify livestock-house static pressure after installation and adjust the overall ventilation system where necessary.
• Replace damaged or deformed panels promptly to maintain uniform air intake performance.

Q: What is a self-balancing air inlet?
A: It is a pressure-responsive ventilation inlet whose flap panels open automatically when the exhaust system creates sufficient negative pressure.

Q: Does the inlet require an electric motor to open?
A: Normal opening is driven by the pressure difference created by the exhaust ventilation system, so a separate actuator is not required for the basic self-balancing function.

Q: Where is this model mainly installed?
A: The current product is designed primarily as a secondary air inlet for pig-house corridors.

Q: When is the inlet normally used?
A: It is particularly suitable for summer and other periods when the pig house requires increased fresh-air intake.

Q: Can several inlets be installed together?
A: Yes. Multiple inlet modules can be arranged along the ventilation wall according to the required total inlet area.

Q: Can it work with negative pressure exhaust fans?
A: Yes. The inlet is specifically designed to respond to the negative pressure generated by mechanical exhaust fans.

Q: How is the required inlet quantity calculated?
A: Selection should consider total exhaust airflow, target static pressure, inlet dimensions, opening characteristics and the overall livestock-house ventilation layout.

Q: Can the inlet be used with cooling pads?
A: Yes. It can be incorporated into a broader summer ventilation and cooling system when the complete airflow path is designed accordingly.
