Product Introduction
For outdoor ventilation systems, specialized EC radial blade centrifugal fan models are designed to withstand harsh environmental conditions. The housing is constructed from thickened galvanized steel with additional anti-corrosion surface treatment to resist rain, ultraviolet radiation, and other environmental factors.
The protection level can reach IP54, while the control board is fully sealed using resin encapsulation to prevent water and dust from entering the motor system.
The motor is designed to operate across extreme temperatures from -40°C to 80°C, ensuring stable performance in challenging climates.
These fans also feature strong wind resistance and reliable operation in outdoor environments such as industrial outdoor equipment, open warehouses, and rail transit infrastructure.

For agricultural applications, EC radial blade centrifugal fans are optimized for environments such as livestock farms and greenhouses.
These fans feature corrosion-resistant materials, dust resistance, and low noise operation, making them suitable for humid and dusty agricultural environments.
Airflow can be adjusted according to farm size, livestock species, and ventilation requirements, ensuring adequate air circulation. Proper ventilation helps reduce livestock stress while lowering indoor ammonia concentrations, thereby improving the breeding environment.
The fans operate quietly, ensuring that livestock are not disturbed during rest periods. Additionally, their energy-saving performance significantly reduces long-term operating costs, making them ideal for modern livestock farms and greenhouse facilities.
