FOCUS ON EC FAN ONLY
This EC wall fan is designed for efficient ventilation and air circulation applications where high reliability, energy saving, and compact installation are required. Equipped with an EC brushless external rotor motor and backward-curved impeller, it provides stable airflow performance, high static pressure, and excellent energy efficiency.With an airflow of 401 m³/h and a static pressure of 496 Pa, this EC fan is suitable for various ventilation systems, including commercial buildings, industrial equipment, air handling units, and HVAC applications. The IP55 protection design allows the fan to operate reliably in environments with dust and moisture exposure.The backward-curved impeller structure ensures smooth operation, low vibration, and reduced energy consumption compared with traditional AC fans. The integrated EC motor supports intelligent speed control through 0-10VDC/PWM input, enabling flexible adjustment according to different ventilation requirements.This EC wall fan is widely used in ventilation systems, cooling equipment, air purification systems, electrical cabinets, and industrial machinery. With a long service life of up to 50,000 hours (L10), it provides a dependable and energy-efficient solution for OEM customers and system integrators.
