Oxygen (O₂) is a colorless, odorless gas that is essential to life and industry. As the second most abundant element in the Earth’s atmosphere, oxygen is critical not only for human respiration but also for combustion, chemical reactions, and various manufacturing processes. Its highly reactive nature makes it valuable across many sectors—but also introduces safety challenges when storing and handling it under high pressure.
Because of its chemical reactivity, oxygen must be compressed using specialized equipment that avoids contamination, overheating, or the risk of explosion. That’s where oxygen compressors—especially oil-free and diaphragm types—come into play.
Modèle: GV-5/4-150
Débit: 5Nm³/h (Standard conditions: 0°C, 1 atm)
Pression d'entrée: 4 bar (Customizable range: 3–8 bar)
Pression de refoulement: 150 bar (Max. 3200 bar for ultra-high-pressure needs)
Stades de compression: 2-stage optimized design
Options d'entraînement: Variable-speed electric motor
Système de refroidissement: Air + refroidissement à l'eau entre les étages (assure la stabilité thermique)
Système de contrôle: PLC intelligent + HMI (surveillance en temps réel de la pression, de la température, des vibrations)
Compressed oxygen is indispensable in the following industries:
Medical and Healthcare
Oxygen therapy
Respiratory support
Emergency cylinder filling
Metal and Welding
Oxy-fuel cutting and welding
Blast furnaces in steel manufacturing
Traitement chimique
Oxidation reactions
Reactor feed gas
Aerospace and Aviation
Cabin pressurization and life-support systems
Environmental and Water Treatment
Ozone generation for purification
In each of these applications, high purity et la sécurité are paramount, which is why selecting the right type of oxygen compressor is critical.
These compressors are widely used for high-purity applications. The diaphragm design separates the oxygen from the compressor’s moving parts, ensuring that the gas never comes in contact with oil or metal surfaces.
Avantages :
Zero contamination
Ideal for 99.999% purity
Convient pour les débits faibles à moyens
Well-suited for larger flow rates and high-pressure cylinder filling, oil-free piston compressors are rugged and relatively simple to maintain.
Avantages :
High discharge pressure (up to 300 bar)
Reliable for long-term, continuous operation
More cost-effective than diaphragm models for large volumes
Scroll compressors are commonly found in medical centers where lower pressures and quiet operation are needed.
Avantages :
Quiet and compact
Ideal for dental and clinical settings
Low maintenance
In 2024, a leading industrial gas distributor in the Philippines reached out to KEEPWIN for a reliable solution to compress high-purity oxygen from a PSA generator into storage cylinders. The client was looking for a safe, clean, and compact unit for indoor installation.
After an in-depth technical consultation, our engineers recommended the GV-5/4-150 diaphragm compressor.
Model: GV-5/4-150
Débit : 5 Nm³/h
Pression d'entrée : 0.4 MPa (from PSA oxygen generator)
Pression de refoulement : 15 MPa (150 bar)
Design Type: V-type diaphragm structure
Système de refroidissement : Water-cooled for enhanced heat dissipation
Oxygen Purity Support: ≥ 99.5%
100% Oil-Free Operation
Stainless Steel Wetted Parts (316L)
Dual Safety Relief Valves
PLC-Based Control with Auto Stop/Start Functions
The unit was shipped and installed in Quezon City, where it was integrated with a PSA generator and a vertical oxygen cylinder manifold.
Installation Time: 3 Days
Initial Output: 25 cylinders/day
Efficacité énergétique : Reduced power consumption compared to legacy piston systems
Client Feedback:
“The GV-5/4-150 runs quietly and safely. We are impressed with the engineering and the support from Keepwin’s technical team. It was the perfect match for our PSA system.”
The client has since ordered two additional compressors for separate hospitals in Cebu and Davao.
