Four-Way Pig House Ceiling Air Inlet

• Four-Way Air Distribution: Directs incoming fresh air toward multiple directions for improved room-air mixing.
• Ceiling-Mounted Design: Uses overhead space efficiently and supports centralized ventilation layouts.
• High-Impact PS Housing: Durable molded construction is suitable for demanding livestock-house environments.
• Adjustable Air-Guiding Blades: Blade angle can be changed to regulate airflow direction and inlet opening.
• Automatic Ventilation Control: Can be configured to adjust according to exhaust fan stages and climate-control requirements.
• Reduced Direct Draft Risk: Ceiling-level air distribution helps mix incoming air with warm room air before it reaches pigs.
• Uniform Fresh-Air Distribution: Multiple inlets can be arranged along the pig house to improve ventilation consistency.
• Suitable for Negative-Pressure Systems: Works with exhaust fans to control fresh-air entry under negative pressure.
• Easy to Clean: Smooth molded surfaces support routine livestock-house washing and sanitation.

• Commercial pig houses
• Piglet nursery houses
• Farrowing houses
• Sow gestation buildings
• Breeding pig houses
• Finishing and fattening pig houses
• Negative-pressure ventilation systems
• Ceiling fresh-air distribution systems
• New-build and pig-house renovation projects

• Determine inlet quantity and spacing according to house dimensions and required ventilation capacity.
• Position the air inlets evenly along the ceiling to promote uniform fresh-air distribution.
• Prepare ceiling openings according to the selected inlet dimensions.
• Install the inlet body square and level to ensure smooth blade movement.
• Connect the opening mechanism to the ventilation-control system when automatic operation is required.
• Adjust blade angles during commissioning to achieve appropriate air throw and mixing.
• Avoid directing high-velocity cold air directly toward resting pigs.
• Inspect blades, hinges, linkages and control components regularly.
• Remove dust and accumulated contamination from the inlet surfaces during routine barn cleaning.
• Recheck inlet calibration when ventilation stages or exhaust-fan configuration are changed.

Q: Where is the four-way air inlet installed?
A: It is designed for installation in the ceiling of enclosed pig houses.

Q: Why is it called a four-way air inlet?
A: The inlet directs incoming fresh air toward multiple sides around the ceiling opening to improve room-air distribution.

Q: What material is the housing made from?
A: The listed housing is manufactured from high-impact polystyrene material for strength and durability.

Q: Can the blade angle be adjusted automatically?
A: Yes. The product can be configured so blade opening changes according to exhaust fan stages and ventilation demand.

Q: Does it work with negative-pressure ventilation?
A: Yes. Exhaust fans create the pressure difference that draws fresh air through the ceiling inlets.

Q: How does it help reduce cold drafts?
A: The inlet distributes fresh air near the ceiling so it can mix with warmer house air before reaching the pig-occupied zone.

Q: How many air inlets are required for one pig house?
A: Quantity should be calculated according to building dimensions, pig numbers, ventilation stages, exhaust capacity and the required inlet airflow.

Q: Can the inlet dimensions and control system be customized?
A: Yes. Inlet configuration, installation layout and control linkage can be selected according to the pig-house ventilation project.
