Spring-Loaded Pig House Ceiling Air Inlet

• Butterfly Opening Structure: Disc-style opening increases effective air-exchange area and supports aerodynamic airflow distribution.
• Double-Sided Air Intake: Fresh air is distributed toward both sides of the livestock house for more uniform ventilation.
• Up to 3600 m³/h Airflow: Listed maximum airflow reaches approximately 3600 m³/h at 20 Pa static pressure.
• Manual & Automatic Control: Can be operated manually or connected to an automatic ventilation-control system.
• AC810 Controller Compatible: Opening angle can be automatically adjusted according to environmental-control requirements.
• Ceiling-Mounted Design: Fresh air enters above the animal zone and mixes with indoor air before descending.
• Adjustable Opening Angle: Allows inlet capacity and air velocity to follow changing ventilation demand.
• Cold-Draft Reduction: Ceiling-level airflow helps reduce direct cold-air impact on pigs during minimum ventilation.
• Corrosion-Resistant Construction: Professional livestock inlet systems use durable engineering plastic components suitable for humid farm environments.
• Spring-Assisted Configuration: Spring-return components can support reliable closing and stable inlet positioning depending on configuration.

• Commercial pig houses
• Piglet nursery houses
• Sow farrowing houses
• Sow gestation buildings
• Breeding pig houses
• Finishing and fattening pig houses
• Poultry and livestock buildings
• Minimum and transition ventilation systems
• Negative-pressure ventilation systems
• Automatic livestock climate-control projects

• Calculate inlet quantity according to total ventilation capacity and required operating static pressure.
• Distribute the air inlets evenly along the livestock-house ceiling.
• Keep each inlet level so both butterfly panels open symmetrically.
• Connect the mechanical pull system or actuator according to the selected control configuration.
• Adjust the opening angle during commissioning to achieve suitable air throw along the ceiling.
• Verify that incoming cold air does not fall directly onto resting animals.
• Check springs, cables, pulleys, hinges and linkage components regularly.
• Remove dust and accumulated contamination from the inlet panels and housing.
• Inspect sealing surfaces and replace damaged sealing components when required.
• Recalibrate automatic opening positions after changes to exhaust-fan stages or ventilation settings.

Q: Where is the spring-loaded air inlet installed?
A: This configuration is designed for installation in the ceiling of pig houses and other enclosed livestock buildings.

Q: How does the butterfly structure work?
A: The two inlet panels open toward opposite sides, increasing the effective opening area and distributing fresh air in both directions.

Q: What is the maximum listed airflow?
A: The product page lists a maximum airflow of approximately 3600 m³/h at 20 Pa static pressure.

Q: Can it be operated manually?
A: Yes. The inlet supports manual and automatic integrated control.

Q: Can it be connected to an environmental controller?
A: Yes. The listed configuration supports automatic opening control using an AC810 environmental controller.

Q: Why is ceiling air distribution useful in winter?
A: It helps incoming cold air travel along the ceiling and mix with warmer indoor air before entering the animal zone, reducing direct drafts.

Q: How many air inlets are required?
A: Quantity depends on total exhaust capacity, operating static pressure, house dimensions, stocking density and required minimum ventilation.

Q: Can the size and control configuration be customized?
A: Yes. Inlet dimensions, linkage system and automatic-control configuration can be selected according to the livestock-house ventilation project.
