What Is AC Backward Curved Centrifugal Fans?
As leading fans Chinese factory, China is a reliable supplier and manufacturer of AC backward curved centrifugal fans, offering OEM services.We will tell you more about AC Backward Curved Centrifugal Fan below:
AC (Alternating Current) backward curved centrifugal fans utilize traditional AC induction motors. These motors operate at a fixed speed determined by the frequency of the supplied AC power. AC fans typically have fixed speed settings or may offer limited speed control through external devices like rheostats or variable frequency drives (VFDs).
- Aerodynamic Design – Curved impeller blades are angled backward relative to the air flow direction.
- Airflow Pattern – Air enters axially and is discharged radially at 90 degrees from the inlet. Provides high pressure airflow.
- Single Width Fans – Most common design with single impeller width for general ventilation uses.
- Double Width – Two impellers housed side-by-side for higher airflow volumes.
- Motors – Commonly powered by AC induction motors in direct drive or belt drive arrangements.
- RPM Range – Typically 900 to 3,000 RPM for 60Hz power depending on impeller diameter and airflow needs.
- Performance – Capable of high airflow volumes at relatively low pressures. Not suitable for high pressure applications.
- Limitations – Limited pressure capabilities. Not suitable for high static pressure situations.
When BELMONT AC Backward Curved Centrifugal Fans Compare To EC Type
The main difference between AC and EC backward curved centrifugal fans lies in the type of motor used in each. We will list the 5 differences below:
- Speed Control: EC fans offer variable speed control, allowing for precise modulation of airflow, while AC fans typically operate at a fixed speed.
- Energy Efficiency: EC fans are generally more energy-efficient compared to AC fans, as they can adjust their speed based on demand, resulting in reduced power consumption.
- Control Capability: EC fans provide enhanced control capabilities, allowing for integration with building automation systems, remote control, and precise regulation of airflow. AC fans, in contrast, have limited control options.
- Noise Levels: EC fans often operate at lower noise levels due to their ability to operate at lower speeds, while AC fans may produce more audible noise.
- Initial Cost: AC fans are generally less expensive upfront compared to EC fans, which may have a higher initial cost due to the advanced technology and controls they incorporate.
