Performance parameters
The performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.
1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20℃ temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.
2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.
