Condition Based Maintenance (CBM) is the future maintenance practice for equipment that is here today. Just as computers have changed the way we conduct business, CBM is changing the way we maintain our equipment while at the same time reducing operating costs.
CBM is a strategy aimed at extending machine life, increasing productivity, and taking machine health to the next level for the lifetime of the equipment.
Unlike preventative maintenance, which is based on servicing a machine at scheduled intervals, CBM is based on specific equipment conditions including operating environment and application.
As illustrated below*, over the years the mind-set of maintenance has evolved from:

Several tools can be used to support CBM, but bypass oil filtration combined with oil analysis are critical to maintain system cleanliness and monitor equipment health.
The oil analysis program recommended for your CBM program needs to contain information about wear metals, additive, contamination (dirt, soot, sulfation, nitration), and physical properties (viscosity, oxidation, TBN). This information should be grouped together to allow easy review.
When developing your report for hydraulics, you will need to add a particle count section on the analysis. This will assure your filtration system is maintaining your particle cleanliness.
As a result, fluid life, component life, and equipment life can be safely extended beyond OEM recommendations.
CBM is not about changing oil and filters - it's about eliminating failures, anticipating the needs of the equipment and extending the equipment's life. In short, it's about slashing your operating cost as much as half.
According to a study done at MIT, approximately 70% of all equipment’s usefulness loss is due to surface degradation.
The root cause of surface degradation in engines, transmissions, hydraulic systems is contamination, which can be found in several forms:
The filtration systems designed to meet these conditions must be able to filter efficiently to below 1 micron since most clearances in both engine and hydraulic systems are around 1 micron. It must be capable of removing liquid and gaseous contaminants that can react in the oils to create oxidation, and in some cases, acid. And for engine oil applications, the base additives of the oil need to be replenished due to depletion of the base additives during normal engine operations.
The puraDYN Oil Filtration System is designed and has been proven to reduce solid contaminant to below 1 micron and, according to independent laboratory validation, is approximately 70% efficient below 1 micron. The system also removes the liquid and gaseous contaminants, and has been validated by an independent laboratory to be 96% water/78% fuel vapor efficient.
The patented release mechanism and formulation of the additive package incorporated in the replacement filter element is extremely effective at replenishing the base additives in engine oil, maintaining the TBN and oxidation levels to well within OEM-recommended levels.
We'll be here to help you begin establishing your own CBM program to substantially reduce your fleet's operating costs and provide a more efficient operation, which will begin reflecting positively on your company’s bottom line.
