Designed for modern poultry houses, this galvanized steel fan with FRP housing and butterfly damper provides reliable high-volume exhaust ventilation for broiler, layer, and breeder houses. Its aerodynamic cone design improves airflow efficiency and reduces discharge resistance, while the durable FRP housing offers excellent corrosion resistance. Available with AC or EC motors, it is suitable for both standard and energy-efficient ventilation systems.
-
What are the main applications of this fan?
This fan is designed for poultry houses, including broiler, layer, and breeder farms. It is mainly used for high-volume exhaust ventilation to remove heat, humidity, dust, and stale air.
-
What is the advantage of the FRP housing and galvanized steel structure?
The combination provides both durability and corrosion resistance. The galvanized steel structure offers excellent mechanical strength, while the FRP housing performs well in the humid and corrosive environment of poultry houses.
-
What is the function of the butterfly damper?
The butterfly damper automatically closes when the fan is not operating, helping prevent outside air, dust, rain, and unwanted heat from entering the poultry house. It also provides a cleaner and more controlled ventilation environment.
-
Is this fan available with both AC and EC motors?
Yes. The fan can be equipped with either an AC or EC motor. The AC version provides a reliable and cost-effective solution, while the EC version offers higher energy efficiency and stepless speed control, making it ideal for modern poultry ventilation systems.
