Production description
Single Inlet Forward Centrifugal fans and blowers are compact units that can be used to either pressurize or evacuate in air moving applications. The impellers are permanently mounted to the external rotors for ease of installation and maintenance-free operation. These units may be mounted in any orientation to provide maximum airflow in minimum areas.
Forward centrifugal blowers always require scroll housing, which is open on one side. The characteristic features of this product series are high efficiency, a low noise level, relatively small air flow with a high increase in static pressure, robust design and space-saving application.

(1)YWF External Rotor Centrifugal Fans are divided into forward centrifugal fan and backward centrifugal fan according to curved blades, which have compact structure, convenient installation, credible running, little noise, energy saving and high efficiency.
(2) Several speed ranks, adapt to both frequency conversion and voltage transformation speed changing active. Our products are widely used in duct fans, roof ventilator, air purifying equipment, air conditioning, and household appliances, etc.
(3)The voltage of the single phase motor is 220V, 50/60 Hz, and the voltage of three phase motors is 380V, 50/60Hz. We can also supply other fan motors with different voltages and frequencies according to clients' requirement.
(4)The safety grade of this series is IP54, and the insulation classes are class B and class F.
(5) The applicable ambient temperature of the fan motors used in condenser is from -30℃~60℃.
(6)The average service life of motors is over 30,000 hours.
(8) Our products have gotten UL approval, CE approval and CCC approval.
