Working Pressure: 0.5Mpa
Air Displacement F.A.D: 44.2 m3/min
Motor Power: 250Hp/185KWHigh efficiency and big air-displacement airend with PMSM ( Permanent Magnet Syn. Motor) is used in Baldor Low Pressure lubricated rotary screw air compressor . That is small motor and big air capacity. The intellegent inverter technology makes a better energy saving efficiency in the range of 0.3Mpa to 0.5Mpa.
Comparison of fixed speed screw compressors, normal variable frequency screw compressors and permanent magnet screw compressors| Compressor Type | Fixed Speed | Normal Variable Frequency Compressors | Permanent Magent Variable Frequency Compressors |
| Connection Mode | Belt/ Direct Coupling | Belt/ Direct Coupling | Integrated Connection |
| Transmission Efficiency | 93%~98% | 93%~98% | 100% |
| Working Pressure | not stable, with loading/unloading process | not very stable pressure if large air consumption fluctuation | stable supplied air pressure |
| Motor Efficiency | 89%~91% | 85%~91%, the motor efficiency is low when the frequency is low | 91%~96%, the motor efficiency could also be high even in low frequency |
| Variable Frequency Range | fixed speed | 50%~100%, the variable frequency range is not wide and can not adapt to the air consumption fluctuation well | 25%~100%, wide variable frequency range and can adjust to the air consumption fluctuation well |
| Noise Level | high | relatively low | low |
| Mechanical Structure | relatively complicated | relatively complicated | simple |
| Reliability | good | good | excellent |
| Mfg. Cost | low | relatively high | high |
There is also a remote monitoring system to keep close attention to your equipment operation. You can do real-time monitoring wherever you are!
