Oxygen Concentrator Repair & Maintenance
Repair, liter flow verification, filter replacement, and annual PM documentation for all major oxygen concentrator brands. CMS and NFPA 99 compliant service in all 50 states.

A concentrator that delivers reduced oxygen concentration — even briefly — creates immediate patient risk and serious liability exposure. CMS surveyors and state inspectors look specifically for PM documentation that includes liter flow verification and oxygen purity testing.
Medical Equipment Repair Network connects facilities with biomedical technicians who carry the oxygen analyzers and flow meters required for proper concentrator verification. We provide documented liter flow testing, filter service, and written PM records formatted for surveyor review.
Services Included
Liter Flow Verification
Output flow measurement at rated settings using a calibrated flow meter. Results documented per unit — required for CMS PM compliance.
Oxygen Purity Testing
Oxygen concentration verification using an oxygen analyzer. Critical for any concentrator showing clinical inconsistency or after repairs.
Filter Cleaning and Replacement
Intake filter cleaning, internal filter inspection, and replacement as needed. Filter service is the highest-frequency PM task for most concentrator brands.
Annual Preventive Maintenance
Full manufacturer PM procedure: cabinet cleaning, filter service, flow verification, alarm testing, electrical inspection, and written documentation.
Component Repair
Diagnosis and repair of compressor issues, sieve bed degradation, flow control faults, and alarm system malfunctions.
PCREE Electrical Safety Testing
Leakage current and ground continuity testing for concentrators as required by NFPA 99. Written test report included.
Equipment We Service
- Stationary oxygen concentrators (Invacare Platinum, Respironics EverFlo, DeVilbiss)
- Portable oxygen concentrators (Inogen, Caire, Respironics SimplyGo)
- High-flow concentrators (5L, 8L, 10L units)
- Dual-flow concentrators
- Concentrators with integrated humidifiers
Frequently Asked Questions
CMS and most manufacturers recommend at minimum annual preventive maintenance for oxygen concentrators in healthcare facility settings. Filters should be cleaned more frequently — every 2–4 weeks in most environments. Any concentrator that has shown inconsistent performance, unusual noise, or reduced output should be serviced immediately.
A technician connects a calibrated flow meter to the concentrator outlet and measures actual delivered flow at each setting (typically 1–5 LPM, or up to 10 LPM for high-flow units). Results are compared against manufacturer tolerances. This measurement, along with oxygen purity if tested, is documented in the service record.
Yes. Oxygen concentrators used in patient care settings are electrical equipment subject to NFPA 99 PCREE testing requirements. The PCREE test documents leakage current and ground continuity and is required for CMS survey compliance.
Oxygen concentrators use molecular sieve beds (zeolite) to separate oxygen from room air. Over time, sieve beds degrade and deliver lower oxygen purity. Degradation is gradual and not always visible — oxygen analyzer testing is the only way to confirm output purity. Facilities with older concentrators (5+ years) should verify purity at each PM visit.
