1. Low noise as the inlet and exhaust port of air motor used Spiral shape. This make air inletting and exhausting along spiral lien to avoid instantaneous fluctuation noise and vibration.
2. High efficiency. Straight type of three lobe rotors can make the less clearance of all the components, which lead the blower more efficiency.
3. Minor vibration. Controlled the rotor precision and variation to get the better dynamically balance, which is free from the vibrations.
4. Stable performance. Good material and precision processing gear in the blower to extend the service life.
5. Clear air transported and free from oil –dust.
