Product feature
1.Rotor
Rotors are asymmetric in profile, backed up by ball bearings and
roller bearings. Operates at a low speed, thereby low in abrasion
and maintenance expenses, air end is long service life.
2.Control panel
Intelligent microcomputer-based control technology can monitor and
control in all aspects the complete machine following your
instructions, remote control realizes unattended operation.
3.Oil filter
Rotary filters are applied to completely remove the impurities in
the lubricating oil, easy to replace and free of oil impregnate.
4.Air filter
Original imported filter material,high efficiency three levels air
separator, keep internal cleanliness of the system effectively.
5.Cooler
The cooler is located separately from the internal isolation of the
chassis,so that the cooling fans would suck air with normal
temperature from outside.Compared to cooling by using the air of
45~65°Cinside the chassis,the cooling fans could save over 30%
energy when the temperature of the air outlet decreases 3~8°C.
6.Excellent quality of motors
Professional customized high efficiency permanent magnet
motor,Compared to normal motors, Permanent magnet motor more
excellent energy saving.protection grade:IP65
7.The air end of compressor is of high efficiency and long life
Excellent SKF bearings are adopted for compressor air end to better
improve their use efficiency,reduce abrasion.and to realize long
term operation with no faults,low noise and long life.
