APN020 Small Air Cooled Oil Free Screw Vacuum Pump For Laboratory / Medical Industry

1. Product Overview

The AIRIPA APN020 small air-cooled oil-free screw vacuum pump is a high-performance oil free screw vacuum pump, one of our premium industrial vacuum pump series. Built on dry screw vacuum technology, this oil free vacuum pump runs completely oil-free to deliver clean vacuum environments without contamination. Adopting air cooling design, it eliminates the need for circulating cooling water, enabling plug-and-play installation and simple maintenance.

This compact screw pump reaches ultimate vacuum up to ≤0.5 Pa, supporting continuous operation from atmospheric pressure to high vacuum conditions. It can extract water vapor, solvents and fine dust while realizing gas and solvent recovery. Widely deployed for new energy, laboratory, medical, semiconductor and food packaging applications, the APN020 customized oil free vacuum pump offers reliable, energy-saving vacuum solutions for diverse industrial processes.

2. Working Principle

Twin screw rotors form a sealed cavity with the pump body, operating with non-contact and friction-free motion driven by synchronous gears. The pump works under fully oil-free conditions to keep the pump chamber clean. With air cooling heat dissipation instead of water cooling, it can extract water vapor, solvents and a small amount of dust, supporting gas and solvent recovery. No intermediate partition inside, featuring short air path, high efficiency and anti-clogging performance.

3. Key Features & Advantages

• Oil-Free & Contamination-Free: Fully dry operation generates clean vacuum, and extracted media can be recycled, avoiding oil pollution to your production line.
• Convenient Air-Cooled Design: No circulating water required. Ready for immediate use after installation, reducing infrastructure cost and simplifying daily maintenance.
• High Efficiency & Energy Saving: Variable pitch rotor technology cuts energy consumption by up to 30%, lowering your long-term operational expense.
• Dual Anti-Corrosion Protection: Stainless steel rotors paired with nano ceramic coating on pump cavity inner wall, improving resistance to corrosive gas.
• Long Service Life: Extended maintenance cycle, running reliably for thousands to tens of thousands of operating hours.
• Excellent Ultimate Vacuum: Continuous operation available from atmospheric pressure down to ≤0.5 Pa.
• Reliable Sealing Structure: Combined dual mechanical seal plus magnetic seal design for smooth liquid discharge and stable sealing performance.
• Lightweight & Low Noise: Aluminum alloy construction reduces overall weight. Precision machining controls noise level at only 69 dB.
• Premium Configuration: Equipped with KEG motor, optional ABB motor (explosion-proof available), SKF shaft sleeves and NSK bearings for stable operation.
