Reliable and efficient gas compression with rotary vane technology
Rotary vane compressors—also known as multi-vane or sliding vane compressors—are a type of positive displacement compressor widely used for both pressure and vacuum generation. Their robust design and smooth operation make them ideal for industrial applications where efficiency and reliability are critical.
Operating principle of rotary vane compressors
- Rotor with sliding vanes
An eccentrically mounted rotor with multiple movable vanes rotates inside a cylindrical housing. - Cell formation
The vanes slide outward by centrifugal force and form crescent-shaped cells between the rotor and housing. - Gas intake and compression
As the rotor turns, gas is drawn into the expanding cells. Once sealed, the volume decreases, compressing the gas. - Gas discharge
The compressed gas exits through the outlet port and is delivered to the system.
Key Advantages
High Efficiency: Smooth, continuous compression reduces energy losses.
Low Vibration: Balanced rotor movement ensures quiet and stable operation.
Long Service Life: Durable materials and simple design reduce wear.
Easy Maintenance: Straightforward construction enables quick service and minimal downtime.
Versatile Use: Suitable for compressed air generation, vacuum applications, and gas transport.
Applications
Industrial Air Supply: Consistent compressed air for manufacturing processes.
Vacuum Generation: Used in packaging, pick-and-place systems, and material handling.
Gas Transport: Handling of process gases in chemical and petrochemical plants.
HVAC Systems: Compression of refrigerants in cooling technology.
Medical Equipment: Supplying clean air for ventilators and other healthcare devices.
