Direct-drive drop hammer exhaust fan features a motor and impeller connected directly via a shaft, no need for belts or couplings. This design reduces friction loss and achieves over 90% transmission efficiency. Known for their high energy efficiency, With motor direct driving impeller, these fans significantly decrease mechanical wear and failure rates. With minimal vibration and low noise levels, they are ideal for industrial workshops and agricultural greenhouse ventilation suitable for long-term, stable operation. The direct-drive design improves transmission efficiency, saving approximately 15%-30% energy compared to traditional belt-driven models.
Drop hammer exhaust fan features a heavy hammer damper design, where the heavy hammer assists the louver and operates by utilizing gravitational force that automatically open when the fan operates and close securely when powered off. This self-regulating damper system ensures optimal airflow control with zero energy consumption during non-operational periods.
