In a rotary vane compressor, compression is accomplished as centrifugal force extends vanes from slots to form individual compression cells. As the cells move around a stator, the trapped air is compressed and expelled from the compression area. These compressors offer up to 100,000+ operating hours due to their simple integral design. They are all direct drive driven with a shock-absorbing coupling system. This eliminates the need for speed increasing gears and over tensioning belts. Maintenance costs are reduced by simple construction and grouped service components. Rotary vane compressors run at a conservative slow speed, making them extremely reliable and extending the life of the machine.
