The Hidden Cost of
“Preventative Maintenance”
Expensive, Misguided, Ineffective
For more than 60 years, Rotary Screw Air Compressors have been maintained using time-based “Preventative Maintenance” and replacing expensive oils, separators, and filters at preset intervals, whether needed or not.
What began as a sensible precaution has proven to be an expensive, misguided, and ineffective routine. These regular “PMs” consume large amounts of oil and parts, while only treating symptoms and failing to address the root causes of oil degradation, corrosion, wear, and fouling that are responsible for most compressor maintenance and repairs.
The Problem with
Rotary Screw Air Compressors
Look No Further Than the Oil
During normal operation, your compressor’s oil is under constant attack from contaminants and oxidation - a destructive chemical reaction between the oil, its additives, and oxygen from the air. This reaction produces acids while steadily depleting protective additives and degrading the oil’s physical, chemical, and performance properties.
As contaminants and acids accumulate and additives deplete, oxidation, acid production, and oil degradation all accelerate and the oil becomes increasingly less effective at lubricating, cooling, sealing, cleaning, and protecting vital compressor components.
How Oil Contamination and Degradation
Impacts Rotary Screw Air Compressors
Driving Maintenance Costs Up and Compressor Reliability Down!
Most Rotary Screw Compressor’s maintenance tasks and associated costs are directly related to the oil. The oil’s condition in service, its physical and chemical properties, contaminants, and additive levels, has a direct impact on not only the oil, but every component the oil touches. The root causes driving most compressor maintenance and repairs are oil contamination and degradation, which produce acids and accelerates corrosion, wear, and fouling. The result is increased maintenance frequency, greater parts consumption, and higher costs from reduced life of the compressor’s oil, separators, filters, bearings, shaft seals, oil coolers, thermal valves, and more.
Treat the Disease Not the Symptoms
Proactive, Reliability-Centered Maintenance for the 21st Century
The days of wasting time and money with routine PMs and regularly replacing your compressors’ oil and parts, are over. Fluid Metrics’ PuroLube PLUS Compressor Maintenance System proactively targets the root causes of oil degradation, corrosion, wear, and fouling - treating the diseases, not just the symptoms. By focusing on the source of most compressor problems – the oil – and using the latest technologies and maintenance best practices, PuroLube PLUS enables rotary screw compressor users to take control of their compressors maintenance and:

The Proof is In the Data
PuroLube PLUS: Trusted & Verified by Compressor Users Worldwide
Oil analysis data compiled over a decade shows the capabilities of Fluid Metrics’ PuroLube PLUS system. In this study conducted by a user, a Compressor Oil Purifier (COP) with Ion Exchange Technology was installed on a 200 HP compressor filled with 30 gallons of the OEM’s PAG oil. The COP was installed after the oil already had one year (8,000 hours) in service and had exceeded the OEM's recommended TAN change point of 1.0. For the next 10+ years, the COP’s elements were routinely replaced and small doses of PuroLube XTEND additive concentrate were periodically added, and oil samples were analyzed quarterly to monitor the oil’s TAN (leading indicator of the oils oxidative state and remaining useful life) and other critical properties.
The adjacent graph shows the condition of the OEM’s oil “before and after” using the PuroLube PLUS System. The green line depicts the typical TAN increase and service life of the OEM’s oil before using oil purification (COP) and additive replenishment (PuroLube XTEND). Compare this to the orange line after the PuroLube PLUS system was deployed, which shows a dramatic reduction in the oil’s TAN, followed by sustained control of the oil’s acids. After more than 10 years, all of the oil’s critical properties (TAN, viscosity, pH, and additive levels) remained well within their acceptable limits. The result – a more than 90% decrease in oil consumption, waste oil disposal, and associated labor and downtime.
10 Year Oil Life And Still Going!
Why Change Your Oil - Maintain It Instead
Purify, Protect & Save!
PuroLube PLUS: Savings You Can Measure
Average 5 Year Oil Life 60% Savings!
Purify, Protect & Save
Time-based Preventative Maintenance has one benefit – it generates a steady stream of highly profitable oil and parts sales for the compressor OEMs and their distributors. But for compressor users paying those bills, this practice is extremely wasteful, costing them dearly over the life of their compressors.
Comparing the costs of “consumables” (oil, separators & filters), a typical 400 HP compressor using OEM oil and parts and maintained per the OEM’s guidelines, will cost on average more than $14,000 per year in oil and parts, or more than $283,000 over its 20 year life.
By contrast, the same 400 HP compressor using PuroLube Plus will only cost about $6,000 per year, or $103,000 over its life, for an average savings of more than 60%! These savings do not include additional savings from reduced labor, downtime, energy consumption, waste disposal, and fewer repairs.

"We’ve seen a dramatic decrease in our compressors maintenance costs since switching to PuroLube PLUS. The system's ability to maintain our compressors’ oils in like-new condition has drastically decreased our oil and parts consumption. PuroLube PLUS has been a total game changer, saving us both time and money." - Maintenance Manager, Specialty Chemical Plant
"PuroLube PLUS has completely eliminated our need for routine oil and separator changes. By targeting the root causes of oil degradation, corrosion, and wear, our compressors are more reliable than ever. We finally have a maintenance solution that focuses on reliability and performance, rather than just blindly replacing parts." - Lubrication Engineer, Paper Mill
"Fluid Metrics’ Compressor Oil Purifier, PuroLube oil and XTEND additive have kept our compressors running trouble-free for years. We’ve noticed a major reduction in our oil and parts usage, downtime, and far fewer major repairs. I wish we had discovered this system years ago.” Maintenance Technician, Automotive Parts Manufacturer
"Switching from our OEM fluid to PuroLube PLUS has reduced our oil consumption and waste disposal by over 80%. Not only has it cut our maintenance expenses in half, but it also has helped us meet our environmental goals. PuroLube PLUS is an essential tool for any facility with air compressors that is looking to reduce waste and maximize compressor uptime." Maintenance Supervisor, Fiber Extrusion Facility
“Most of our compressors run 24/7 in a hot, dirty, and dusty environment where high temperatures and high particle counts lead to reduced oil life, high separator pressure drops, and premature replacement. Since installing the PuroLube PLUS system, our compressor temperatures, Acid Numbers, and ISO Particle Counts are all down, and we’re getting 2-3 times longer oil and separator life. Reliability Engineer, Mineral Processing Facility
