Oxygen Generator Maintenance Services
Advanced Gas Technologies (AGT) provides expert maintenance services for Pressure Swing Absorption (PSA) and Vacuum Pressure Swing Absorption (VPSA) oxygen generators. Whether your generator was installed by AGT or another provider, we offer 24/7 emergency response, structured preventative maintenance programs, and the technical experience to keep your oxygen supply running to specification.
When your PSA or VPSA system is supplying oxygen to an active production process, a degraded purity reading or an unplanned fault isn't a scheduling inconvenience. It's a production problem. Since 1994, we have installed and maintained industrial gas generating systems for operations throughout the United States, Canada, Mexico, and internationally. If your oxygen generator requires service, contact us to schedule an assessment.
Oxygen Generators We Maintain
AGT services both PSA and VPSA oxygen generating systems. AGT's PSA systems come with a touchscreen controller equipped with an integrated oxygen analyzer, purity and pressure alarms, maintenance advisory outputs, and optional remote monitoring capability. Our VPSA systems have similar features but are designed for higher-volume applications.
Where a PSA system's primary mechanical service points are its compressed air supply, filtration train, and switching valves, a VPSA system adds the blower and vacuum extractor pump as critical rotating components that require their own inspection schedule.
Oxygen Generator Maintenance Services
Keeping an oxygen generator running to specification requires attention to more than just the obvious failure points. Our maintenance services are structured around that reality and include:
Preventative Maintenance Contracts
AGT's preventative maintenance programs cover inspection of all primary system components including molecular sieve beds, switching valves, compressed air filtration, instrumentation, and control systems on a defined schedule aligned with your system's operating hours and manufacturer guidelines.
24/7 Emergency Support
When an unplanned fault occurs, fast response is critical. AGT offers around-the-clock emergency service support for oxygen generator systems across the United States, Canada, and most international regions through our global network of service partners. Our technicians provide remote diagnostic support and, where on-site attendance is required, dispatch service personnel with the tools and spare parts needed to restore your system to operation with minimal downtime.
Switching Valve Inspection & Replacement
Switching valves are among the highest-wear components in a PSA oxygen generator. They cycle continuously throughout operation, controlling the alternating pressurization and depressurization of the adsorber towers that makes oxygen separation possible. Our technicians inspect valve condition as part of scheduled service visits and carry out rebuilds or replacements as required, using compatible replacement components and documenting the work against your system's service record.
Air Inlet Filter Replacement
The quality of the compressed air feeding your oxygen generator directly determines how long the zeolite molecular sieve beds perform to specification. Our technicians inspect and replace filter elements on a schedule aligned to your system's operating hours, confirm that compressed air dewpoint is within the required range, and flag any upstream compressor or dryer issues that may be introducing contamination before they reach the generator.
Oxygen Purity Monitoring
We service and calibrate oxygen analyzers as part of scheduled maintenance visits and can supply replacement sensor cells when required. Maintaining calibrated, functional purity monitoring is essential for any application where oxygen concentration directly affects process quality or safety.
System Pressure Checks & Leak Inspection
Undetected leaks in the piping, fittings, or adsorber vessels reduce system efficiency, affect oxygen purity output, and can indicate more serious component wear. Our technicians perform systematic pressure checks and leak inspections using appropriate detection methods for oxygen-compatible systems, documenting findings, and completing any required repairs during the same service visit where possible.
Maintenance Training
AGT provides on-site operator training to equip your team with the knowledge to manage and monitor your oxygen generator effectively between scheduled service visits. Training covers correct operating procedures, routine inspection tasks, how to interpret controller displays and maintenance advisory messages, and when to escalate an issue to a service technician.
Why Choose Advanced Gas Technologies
AGT has been supplying, installing, and maintaining industrial oxygen generating systems since 1994. That operational history means our technicians understand how PSA and VPSA systems perform across a wide range of applications, environments, and duty cycles and how to identify degradation patterns before they become failures. Whatever system you are running, our technicians can assess its condition and design a maintenance plan that matches your production requirements.
Frequently Asked Questions About Maintaining Oxygen Generators
Will AGT service an oxygen generator that your team did not install?
Yes. AGT provides maintenance services for PSA and VPSA oxygen generators regardless of the original installer or equipment manufacturer. Our technicians can assess your existing system, establish a baseline service record, and develop a maintenance program appropriate for your system type, operating hours, and application requirements.
What is included in a preventative maintenance contract for an oxygen generator?
A preventative maintenance contract from AGT includes scheduled inspections of all major system components: molecular sieve beds, switching valves, compressed air filtration train, oxygen purity analyzer, instrumentation, and control systems. Service intervals are set based on your system's operating hours and manufacturer guidelines.
How do I know if my oxygen generator needs service?
Common indicators that your oxygen generator requires attention include:
- A decline in oxygen purity output
- Maintenance advisory messages on the controller display
- Unexplained changes in system pressure
- Audible changes in valve or blower operation
- Visible moisture or contamination in the compressed air supply upstream of the generator
If your system is producing oxygen below your required purity specification or showing any of these signs, contact AGT's service team for an assessment.
How often should an industrial oxygen generator be serviced?
Service intervals depend on your system type, operating hours, and the quality of the compressed air feed. As a general guide, compressed air inlet filters should be inspected and changed on a regular schedule based on operating hours; oxygen purity analyzers require periodic calibration and eventual sensor cell replacement; and switching valve components on PSA systems typically require inspection in the range of 30,000 to 40,000 operating hours. A preventative maintenance contract establishes a defined schedule aligned to these intervals, so nothing is missed.
