The motor type of side channel blowers (also called ring blowers or regenerative blowers) can use either AC or DC, depending on the design and application requirements. The following are common usage scenarios for the two power sources:
1. AC motor (AC)
More common: Most industrial side channel blowers use AC motors (such as single-phase AC 220V or three-phase AC 380V) because of their simple structure, easy maintenance, and direct access to the power grid.
Features:
· No additional power conversion is required, suitable for fixed installations (such as sewage treatment, pneumatic conveying, etc.).
· Usually used with capacitor operation or asynchronous motors, speed regulation requires a frequency converter.
2. DC motor (DC)
Specific scenarios: Small or portable side channel blowers may use DC motors (such as 12V/24V DC), which are common in vehicles, solar equipment, or mobile applications that require battery power.
Features:
· More flexible speed regulation (through PWM control), suitable for scenarios requiring precise air volume regulation.
· Higher efficiency, but requires additional DC power supply or battery support.
Key distinguishing factors:
Application environment: Industrial equipment mostly uses AC, while mobile or low-power equipment tends to use DC.
Power supply conditions: Check the voltage/current type marked on the equipment nameplate or manual.
Control requirements: If variable frequency speed regulation is required, AC motors need to be equipped with inverters; DC motors can directly adjust voltage or PWM.
