Two Stage PM VSD

Single Stage screw compressor compress air from 1 bar directly to 8 bar or 10 bar with one airend. Due to high compression ratio, there will be air leakage during the compression process. Two-stage compression screw compressor uses two different airends for the compression process.
The compression ratio of two stage compressor is smaller than that of single stage compressor, which reduce the
compression air leakage. Accordingly, improved the free air delivery. With same motor power, Two stage compression screw compressor can provide more air delivery than single stage compressor.

Advantages of Two-stage PM VSD Screw Compressor

• Adopt customized energy-saving two-stage compression airend profile, the airend is more efficient
• Oil spray cooling is adopted to improve the efficiency,
• With the same power, the air delivery can be increased by 15%
• Low RPM design, The Compressor runs more quietly
• With permanent magnet frequency conversion technology, no matter full load operation or fluctuating air demand, the compressor can maintain high efficiency
• VSD start ensures low starting current and avoids the impact of power grid
