Pig House Sliding Curtain Air Inlet System

• Secondary Air Inlet Design: Developed for pig-house corridors and multi-stage ventilation systems.
• Vertical Sliding Adjustment: The curtain panel moves up and down to continuously change the effective inlet opening.
• Manual & Automatic Control: Integrated drive configurations support both manual operation and automatic environmental control.
• Rigid Curtain Panel: Typical systems use corrosion-resistant PVC panels with a smooth surface suitable for livestock-house environments.
• Stable Guide Structure: Vertical guide rails help keep the panel aligned during repeated opening and closing.
• Cable & Pulley Drive: Stainless steel wire rope and low-friction pulleys can be configured for reliable lifting transmission.
• Precise Airflow Regulation: Adjustable opening area allows airflow to be matched to seasonal ventilation requirements.
• Cooling Pad Integration: Can be incorporated into summer ventilation systems using evaporative cooling pads where required.
• Customized Dimensions: Panel width, opening height, guide structure and drive configuration can be designed according to the building opening.
• Commercial Farm Application: Suitable for large-scale pig farms using staged, negative-pressure or tunnel ventilation strategies.

• Commercial pig-house corridors
• Secondary pig-house air inlets
• Sow gestation and farrowing buildings
• Piglet nursery houses
• Finishing and fattening pig houses
• Multi-stage ventilation systems
• Negative-pressure ventilation systems
• Tunnel ventilation systems
• Evaporative cooling pad installations
• New-build and pig-house renovation projects

• Measure the air-inlet opening accurately before manufacturing the curtain panel and guide structure.
• Install both vertical guide rails parallel and plumb to ensure smooth panel movement.
• Position lifting cables symmetrically so the curtain panel remains level during operation.
• Adjust pulleys, cables and drive components to prevent binding or uneven lifting.
• Set upper and lower travel limits before commissioning an automatic drive system.
• Verify that the fully open position provides the required design inlet area.
• Inspect lifting cables, pulleys, fasteners and guide rails regularly for wear or looseness.
• Keep guide surfaces clean and free from accumulated dust and debris.
• Inspect the PVC curtain panel for cracks, deformation or damaged edges.
• For automatic systems, periodically test controller signals, limit switches and emergency manual operation.

Q: What is the sliding curtain system used for?
A: It is a secondary pig-house air inlet used to regulate summer and transition-season ventilation.

Q: How is the inlet opening adjusted?
A: The rigid curtain panel moves vertically up or down to increase or decrease the effective inlet opening.

Q: Can it be operated manually?
A: Yes. Manual lifting or winch configurations can be supplied.

Q: Can the sliding curtain operate automatically?
A: Yes. Automatic electric-drive versions can be connected to compatible livestock-house environmental control systems.

Q: What material is normally used for the sliding panel?
A: Professional livestock sliding-curtain systems commonly use rigid PVC panels because they provide corrosion resistance, a smooth surface and good dimensional stability.

Q: Can the dimensions be customized?
A: Yes. Panel dimensions, guide height, cable arrangement and drive configuration can be manufactured according to the building opening.

Q: Can it be installed with cooling pads?
A: Yes. Sliding curtain air inlets can be integrated with evaporative cooling-pad systems when required by the summer ventilation design.

Q: What is the difference between a sliding curtain and a flexible curtain?
A: A sliding curtain normally uses a rigid panel moving vertically in guide rails, while a conventional flexible curtain uses coated fabric that rolls, folds or lifts to change the opening.
