EC Ventilation Backward Curved Centrifugal Fans With Equipment Cooling Fan

• Noise-optimized air outlet in scroll housing.
• Pressure-optimized blower
• shaded pole motor
• Impedance protected.

1． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and easy to abstract heat., thus ensure to maximum the reliability of fan operation,

2． Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system,

3． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation

• Size: 220mm diameter X 64mm
• Material: spiral housing of fiberglass-reinforced plastic scroll housing base of aluminum sheet.
• Fully integrated electronic commutation.
• Protect against reverse polarity and locking.
• Direction of air flow: axial air intake, centrifugal air exhaust out of the outlet.
