Factory Supply Customizable Air Circulation Fan, 400/500mm, 304 Stainless Steel, Low Noise, High Airflow for Greenhouse Ventilation

Air circulation fan is an ideal solution for evenly distributing air and temperature in various environments, especially designed for greenhouse, livestock, and poultry house ventilation. Available in two blade diameters—400mm or 500mm—this fan features a 304 stainless steel housing for maximum corrosion resistance and aerodynamic aluminum alloy blades, ensuring durability and efficient airflow.

Product Specifications (Key Models):

For KH(A) - 400: Blade Diameter 400mm, Voltage 220/380V, Frequency 50Hz, Power 180W, Rotated Speed 1400 RPM, Air Volume 5300 m³/h.

For KH(A) - 500: Blade Diameter 500mm, Voltage 220/380V, Frequency 50Hz, Power 250W, Rotated Speed 1400 RPM, Air Volume 6300 m³/h.

Additional models (ZCHL series) offer options like single/three - phase voltage, with air volume ranging from 3900 to 5900 m³/h, ensuring flexibility for different ventilation needs.

Working Principle & Application: As a type of wind turbine, the circulation fan converts input mechanical energy to increase gas pressure and move air. It excels in ventilating closed barns, greenhouses, and livestock houses—especially areas with high moisture density. By arranging directional relay ventilation, it fully circulates damp heat air, delivering excellent cooling effects. It’s the ideal equipment for vertical/horizontal airflow and ventilation cooling.

Main Advantages:

1. Direct - driven motor reduces energy losses, enhancing efficiency.
2. Energy - efficient with high - output airflow and low noise levels.
3. Heavy - duty mount bracket for stable installation.
4. Low maintenance and management costs.
5. Quick and easy installation for hassle - free setup.

Key Features:

• Export - specific 'three - proof' motor tailored for high - temperature, high - humidity greenhouse environments, ensuring smooth operation.
