- The above performance is based on standard condition of ambient temperature 20℃ and atmospheric pressure of 1,013 mbar.
- The performance tolerance is ±10%.
- The noise is measured at distance of 1.5 m with the inlet and outlet completely open.
- Inquire about ring blowers that require special treatment such as corrosion treatment or use of explosion-proof motors.
Performance Curve

- Continuous operation around the rated pressure may damage the motor due to overheating, so appropriate measures such as installing a relief valve are required( refer to the parts and the accessories page).
- The performance tolerance is ±10%.
