AIRIPA APWX Series Oil Free Scroll Vacuum Pump from
1. Product Overview
The AIRIPA APWX Series Oil Free Scroll Vacuum Pump is designed for applications requiring clean, low-noise vacuum generation without lubricating oil in the pumping chamber. Its integrated scroll mechanism combines a stationary scroll and an orbiting scroll to compress and discharge gas through a dry pumping process.
The series includes APWX6, APWX10, APWX16, APWX36 and APWX45, with listed pumping speeds from 6 to 45 m³/h. Air cooling, compact construction and replaceable tip seals make these pumps suitable for laboratories, research equipment, industrial processes and OEM vacuum systems.
For customers seeking an alternative to oil-sealed vacuum pumps, the APWX Series offers a practical solution for compatible applications where cleanliness, manageable noise and simplified maintenance are important.
2. Key Features & Benefits
Oil Free Scroll Technology
The dry scroll mechanism operates without lubricating oil in the pumping chamber, helping reduce oil-related contamination.
Clean Vacuum Generation
Oil-free gas compression supports applications where clean vacuum conditions are important for process quality.
Low Noise Operation
Specified noise levels of 54–56 dB(A), depending on the model, make the series suitable for noise-sensitive equipment environments.
Air Cooled Design
Integrated air cooling eliminates the need for external cooling water and simplifies installation.
Five Pumping Capacities
Models with listed pumping speeds from 6 to 45 m³/h allow customers to select a capacity suited to their equipment.
Water Vapor Handling
Specified water vapor handling capacities support selected moisture-containing processes when operated within recommended conditions.
Replaceable Tip Seals
The scroll tip seals are designed for routine replacement, helping simplify scheduled maintenance.
Compact Integrated Structure
The motor and pumping mechanism form an integrated unit suitable for laboratory installations and OEM equipment.
Standard KF Connections
KF25 and KF40 inlet options provide convenient connections to compatible vacuum piping and equipment.
3. Working Principle
The APWX oil free scroll vacuum pump uses a stationary scroll and an orbiting scroll to create a series of enclosed gas pockets.
As the orbiting scroll moves, gas enters through the inlet and becomes trapped between the scroll elements. These gas pockets gradually move toward the center of the mechanism, decreasing in volume and increasing in pressure.
The compressed gas is then discharged through the exhaust port, completing the pumping cycle. The process operates without oil in the pumping chamber, while replaceable tip seals help maintain sealing performance.
