This accessory is an external rain canopy for butterfly side air inlets of livestock houses. It is compatible with aluminum alloy butterfly air inlets used in chicken houses and pig farms, and mounted on the exterior side of the wall.

Two mainstream material options are available: PP engineering plastic.

Integrally molded curved housing

Semi-circular curved flow guiding design ensures smooth airflow with extremely low wind resistance and will not disrupt negative pressure balance inside the house. The curved surface effectively blocks slanting wind and rain.

Flange mounting plate

Standard mounting holes are reserved around the perimeter. It can be bolted directly to the exterior wall or air inlet frame for easy assembly, disassembly and reliable sealing.

Natural water dripping structure

A drip edge is formed at the bottom edge of the housing. Rainwater flows down along the curved outer surface and prevents rain penetration into the air inlet through wall gaps.
