APN Oil Free Air Cooled Dry Screw Vacuum Pump Ultimate Pressure Of ≤0.5 Pa For Industrial
1. Product Overview
The AIRIPA APN Series Oil Free Air Cooled Dry Screw Vacuum Pump is a compact industrial vacuum pump designed for clean, oil-free gas handling. Featuring non-contacting screw rotors, air cooling and an integrated motor-driven structure, it provides a practical vacuum solution for equipment manufacturers and industrial processing systems.
The series includes APN018, APN028 and APN036, with nominal pumping speeds from 20 to 40 m³/h, effective pumping speeds from 18 to 36 m³/h, and a specified ultimate pressure of ≤0.5 Pa.
Its dry pumping chamber, compact construction and simplified cooling requirements make the APN Series suitable for compatible vacuum drying, coating, electronics manufacturing, laboratory and OEM applications.
2. Key Features & Benefits
Oil Free Dry Pumping
Non-contacting screw rotors operate without oil in the pumping chamber, helping reduce process contamination.
Advanced Screw Rotor Design
The compound screw rotor structure supports continuous gas transfer and stable vacuum generation.
High Vacuum Performance
A specified ultimate pressure of ≤0.5 Pa supports industrial processes requiring low operating pressures.
Air Cooled Construction
Integrated air cooling eliminates the need for an external cooling water supply and simplifies installation.
Compact and Lightweight
With listed weights from 30 to 38 kg, the series supports integration into space-constrained equipment.
Continuous Gas Handling
The dry pumping mechanism can handle compatible gas streams without introducing sealing oil into the pumping chamber.
Reliable Mechanical Sealing
The design incorporates mechanical and lip sealing arrangements to help separate the pumping chamber from lubricated components.
Flexible Power Configurations
Power supply options include three-phase 380 V, three-phase 220 V and single-phase 220 V, subject to configuration confirmation.
Industrial OEM Integration
Three pumping capacities and standardized flange connections support equipment matching and system integration.
3. Working Principle
The APN Series uses two synchronized screw rotors rotating in opposite directions within a closely fitted pumping chamber. As the rotors turn, gas enters through the inlet, moves along the screw passages and is discharged through the exhaust.
The rotors operate without contacting each other or the chamber wall, allowing the gas path to remain free from pumping oil. Air cooling removes operating heat, while the drive and sealing components support stable mechanical operation.
The pump can handle compatible process gases, including certain condensable vapors, when suitable operating conditions and protection measures are maintained.

6. Frequently Asked Questions
Q1. What is an oil free dry screw vacuum pump?
An oil free dry screw vacuum pump uses rotating screw rotors to transport gas without introducing lubricating oil into the pumping chamber.
Q2. What is the difference between nominal and effective pumping speed?
Nominal pumping speed is the rated capacity, while effective pumping speed represents the listed usable pumping capacity under the manufacturer's specified conditions.
Q3. Does the APN Series require cooling water?
No. The APN Series uses air cooling, eliminating the need for an external cooling water supply.
Q4. Is the entire vacuum pump completely free of oil?
The pumping chamber operates without oil, but the mechanical drive section requires lubrication and is separated from the gas path by seals.
Q5. Can the APN Series handle water vapor or solvent vapors?
It may be suitable for compatible vapor-containing processes, but operating conditions, condensation risks and gas compatibility must be evaluated before use.
