Oil-free Rotary Vane Vacuum Pump
Leynow · Oil-free Rotary Vane Technology
Oil-lubricated vacuum pumps discharge oil mist, contaminating products and workpieces, accumulating oil stains in the workshop, and causing a decrease in finished product yield.
Requires regular procurement and replacement of vacuum pump oil, increasing consumable procurement costs and occupying daily maintenance hours.
Processes such as food, medical, and hydrogen energy do not allow oil vapor intervention, and ordinary oil-lubricated pumps cannot meet production standards.
Parts such as carbon vanes and filters are difficult to buy, and no corresponding repair technical support can be found when equipment fails.
High-performance graphite carbon vanes rely on self-lubrication of their own material; the pump chamber requires no lubricating oil, exhaust is free of oil mist, and outputs a clean negative pressure air source.
IP54 protected, Class F insulated motor, optimized air-cooled heat dissipation duct, complete machine durability testing, suitable for production line working conditions with long-term non-stop operation.
Intake is equipped with a metal mesh filter to block dust and debris from entering the pump chamber, reducing abnormal wear of carbon vanes and extending the service life of the complete machine.
Modular compact body, occupying small installation space; rotor dynamic balance calibration, low operating noise, improving workshop working environment.
The LX full series has complete specifications, from small-flow laboratories to large-flow industrial production lines, can be used as standalone machines or integrated vacuum systems.
Original factory graphite carbon vanes, intake filter elements, and other wearing parts in stock; providing full technical support for selection, troubleshooting, and factory repair and maintenance.

The LX oil-free carbon vane vacuum pump is a positive displacement dry rotary vane vacuum pump. Three graphite carbon vanes are installed on the rotor in the cylinder. When the rotor rotates at high speed, the graphite carbon vanes are thrown outward by centrifugal force. The vanes tightly adhere to the inner wall of the pump chamber, dividing it into independent variable chambers.
During the suction phase, the chamber expands and draws in gas. During rotation, the chamber volume decreases and compresses the gas, which is finally discharged from the exhaust port. Relying on the self-lubrication of graphite carbon vanes, no vacuum pump oil is required inside the pump body; the intake filter blocks impurities from entering the pump chamber.
The shutdown check valve prevents medium backflow and protects downstream process equipment; the complete machine uses air-cooled heat dissipation and can continuously output a clean, oil-free negative pressure air source for a long time.
Leynow LX series oil-free rotary vane carbon vane vacuum pumps, dry and oil-free, output a clean air source, and are widely used in various industrial equipment and complete systems where oil mist contamination is not allowed.
Oil-free carbon vane vacuum pumps rely on graphite carbon vane self-lubrication to achieve dry operation with no oil mist discharge, suitable for negative pressure working conditions with requirements for air source cleanliness.

Usage Limitations: Not suitable for extracting gases with large amounts of dust, strong corrosiveness, or large amounts of condensable water vapor; graphite carbon vanes are wearing parts and require regular inspection and replacement; not suitable for working conditions requiring ultra-high ultimate vacuum.
Selection Recommendations: For requirements on exhaust cleanliness with no oil mist, prioritize LX oil-free carbon vane vacuum pumps; for pursuing deeper ultimate vacuum, it is recommended to choose oil-lubricated rotary vane vacuum pumps.
Oil-free carbon vane pumps rely on self-lubricating graphite carbon vanes, require no vacuum pump oil, have no oil mist in exhaust, and output a clean air source; the disadvantage is that the ultimate vacuum is weaker than oil-lubricated pumps; oil-lubricated rotary vane pumps have a higher ultimate vacuum but generate oil mist and require regular oil changes; select based on whether the process allows oil mist.
Service life is related to the cleanliness of the extracted medium and operating hours; Leynow original factory can supply graphite carbon vanes and intake filters as a complete set of wearing parts separately.
LX series industrial models support 24h continuous operation, but ventilation and heat dissipation must be ensured; if the medium has a lot of dust, it is recommended to add a pre-filter to reduce carbon vane wear.
The LX oil-free carbon vane vacuum pump is a commonly used model for hydrogen circulation transportation and power generation equipment. It is dry and oil-free, does not produce oil pollution, and can be customized with explosion-proof motors according to working conditions.
