Vane Compressor

Vane Compressor | Komsan Compressed Air Company of Iran

The airend unit in a vane compressor consists of the compression and discharge components. During the intake phase, air enters the compression chamber, which gradually becomes smaller due to the movement of the rotors. At the compression stage, the air outlet is blocked by one of the rotors, while the intake on the opposite side of the chamber remains open to draw in fresh air.

The discharge occurs when one of the rotors opens the channel, forcefully pushing the compressed air out of the chamber. The suction and discharge of air take place radially within the compression chamber, which allows for simpler bearing designs and enhances air-filling efficiency.

Both rotors are synchronized by gears and rotate simultaneously. The maximum pressure ratio achievable by a non-lubricated vane compressor is 4.5. Therefore, for higher pressures, additional compression stages are required.
