Permanent magnet screw variable frequency air compressor is an advanced air compression equipment that combines permanent magnet synchronous motor and frequency conversion technology. It is characterized by high efficiency, energy saving, stability and reliability.
[pdf] The parallel operation of two screw air compressors achieves efficient collaboration through intelligent control, which can not only meet large-scale air demand, but also improve system reliability through redundant design.
[pdf] An internal diesel motor powers these portable compressors and they work in a similar way to electric compressors. The air inside the chamber of the tank is pressurized either by rotating impellers or by collapsing the air containment chamber, which will force the air to compress in a smaller space.
