CE Certified Oil-free High-pressure Oxygen Booster Compressor for Medical Oxygen Supply

An oxygen booster pump is a specially designed compressor used to mechanically increase the pressure of oxygen from a low-pressure source (such as an oxygen cylinder, oxygen generator, or pipeline) to

  • Working Pressure:4~150[ bar ]58~2175[ psig ]
  • Free Air Delivery:2.9~85[ cfm ]0.08~2.4[ m3/min ]
  • Working Power:4~44[ kw ]5~60[ hp ]

Product features

1. Ultimate Safety Design

• Completely Oil-Free Lubrication: The compression chamber is 100% oil-free, completely eliminating the 

risk of combustion and explosion caused by the mixing of oil vapor and high-pressure oxygen.

• Oxygen-Compatible Materials: All components in contact with oxygen are made of oxidation-resistant, 

low-ignition-point materials such as stainless steel, copper alloys, and fluororubber.

• Multiple Safety Protections: Standard features include explosion-proof valves, temperature sensors, and 

pressure-linked shutdown systems for active protection.


2. Guaranteed Medium Purity

• Contamination-Free Compression: The oil-free design and special sealing structure prevent contamination 

from hydrocarbons and particulate matter, maintaining the original purity of the oxygen.

• High Cleanliness Process:  Strict degreasing, cleaning, and nitrogen purging are performed before delivery, 

meeting medical or high-purity gas standards.


3. High Reliability Design

• Low Operating Temperature: Multi-stage compression combined with efficient interstage cooling controls 

the exhaust temperature and slows down material aging.

• Long-Life Components: Wear parts such as piston rings, diaphragms, and valves are optimized for oxygen 

environments, significantly improving durability.
