Material Properties
The FAB series is constructed with a high-strength steel casing and treated with anti-rust spray paint for durability and corrosion resistance. The impeller is designed for low noise and energy efficiency.
Standard models operate on 220V single-phase power, with some larger models available in 380V three-phase versions. The fan is suitable for use in environments with normal temperatures and non-corrosive air.
Benefits
· Energy Efficiency & Low Noise: The optimized impeller design delivers high airflow with low power consumption and quiet operation.
· Weatherproof Design: The external louvers provide excellent rain protection, making it suitable for outdoor wall installations.
· Easy Installation: The compact square design allows for simple mounting on concrete walls or steel panel walls.
Fan Structure
The fan features a square steel casing with integrated louvers and a direct-coupled motor. The simple structure allows for easy access to internal components for cleaning and maintenance.
