An oil-free supercharger can achieve secondary pressurization of non-flammable and explosive gases such as oxygen, nitrogen, argon, helium, carbon dioxide, sulfur hexafluoride, etc., to meet the requirements of the pressurized gas for medical, commercial, industrial, etc. Individual needs for gas.
The new technology patented product, the gas does not contact the bearing, and the compressed components that bear the lateral force are transferred from the high temperature zone to the low temperature zone, and the life of the bearing and the guide ring is doubled. Special supplementary lubrication structure makes maintenance faster
The middle body sealing structure improves the service life of the seals, and the sealing effect is excellent. The leakage is less than four thousandths, which ensures the purity and cleanliness of the gas after pressurization and prolongs the service life of the raw material machine.
An ideal replacement product for traditional turbochargers. Ordinary type (fixed, mobile) box type, variable frequency multiple forms are available.
Applicable gas pressure range:
The gas pressure (≥OMPa) is pressurized to the pressure you need
(≤5.0 Mpa);
Applicable gas flow range: 1 ~300Nm3/h; according to the demand of
the unit type, it is suitable for more air volume.
