Industrial 50-Inch Ventilation Shutter Cone Fan Long Box Blade Variable Speed Exhaust

Our ventilation fans are purpose-built for poultry houses, chicken farms, broiler and layer operations, as well as pig farms, greenhouses, and agricultural warehouses. They deliver high-volume, low-pressure airflow to control temperature, humidity, and ammonia levels, creating a healthy and productive environment for livestock.

The fan housing is made of hot-dip galvanized steel (with optional powder-coated finish) for excellent corrosion resistance in humid farm environments. The blades are precision-balanced aluminum alloy or stainless steel, ensuring smooth rotation, low vibration, and long service life even under continuous operation.

We offer high-efficiency IP55/IP65 protected motors with options for 110V / 220V / 380V / 415V, 50Hz or 60Hz. Direct-drive and belt-drive configurations are available, and all motors are thermal-overload protected for safe 24/7 operation.

Yes. The fan is designed for simple wall-mount or ceiling-mount installation with pre-drilled mounting holes and a complete mounting kit. Maintenance is minimal: the blade and motor are easily accessible for periodic cleaning, and the galvanized housing resists rust without painting.

Noise output is typically 60-75 dB(A) at 3 meters depending on model and speed. Our balanced blade design and high-quality bearings keep vibration and noise at a minimum, which helps reduce stress on the flock.
