A rotary vane blower is a type of positive displacement blower designed to generate airflow by trapping and compressing air or gas using a rotor equipped with sliding vanes. It is commonly used in various industrial and commercial applications where a steady, low- to medium-pressure airflow is required.
Key Characteristics
- Positive Displacement: Ensures a fixed volume of air is moved with each rotation, regardless of changes in backpressure.
- Compact Design: Rotary vane blowers are generally compact and lightweight compared to other types of blowers.
- Low Pulsation: Produces consistent, steady airflow without noticeable pressure surges.
- Variable Configurations: Can be used for vacuum, compression, or both, depending on the application.
Comparison to Other Blowers
- Versus Roots Blower: Rotary vane blowers operate more quietly and with lower pulsation but may handle less extreme pressures.
- Versus Turbo Blower: Rotary vane blowers are simpler, more affordable, and suitable for lower flow and pressure applications.


How It Works
The rotary vane blower operates on a straightforward principle:
Components:
- A cylindrical housing contains a rotor that is mounted off-center.
- The rotor has several vanes (flat blades) inserted into slots, which can slide in and out as the rotor rotates.
Intake and Compression:
- As the rotor spins, the vanes are forced outward by centrifugal force (or sometimes springs) and maintain contact with the inner wall of the housing, forming individual air chambers.
- Air enters the blower through the inlet port into the chamber with maximum volume.
- As the rotor rotates, the chamber volume decreases, compressing the trapped air.
Discharge:
- The compressed air is expelled through the outlet port as the chamber reaches its smallest volume.
