The business case for oil filtration
The same proposal is read three ways. Each section below makes the case for one reader.
The maintenance manager
Maintenance carries the cost of oil failures. The question is whether filtration stops known faults recurring.
What changes
- Inline elements last longer. Clean bulk oil stops them loading early.
- Repeat faults stop. Sticking valves and repeat bearing failures usually trace to 3 to 5 µm silt.
- Analysis trends reverse. Particle counts and wear metals move the right way.
- Oil changed on test results, not by date. A 4,000 litre charge often stays in service years longer.
- Work becomes plannable. Insert changes happen with the machine running.
What to tell your manager
A valve block replaced three times in eighteen months, with oil at ISO 21/19/16 against 16/14/11, is a contamination problem.
What to send us
- Last three oil analysis reports.
- Element cost and change frequency.
- Repeat repair cost and frequency.
- Reservoir litres and oil price per litre.
The plant head
The plant buys availability and deferred capital, not a filter.
Where the return comes from
- Unplanned outage. One avoided day of downtime pays for the installation several times over.
- Deferred rebuilds. Pushing a rebuild back by years is capital avoided.
- Oil purchase and disposal. Less oil bought, and less paid for used oil disposal.
- Labour recovered. Fewer element changes and flushes free technician hours.
Cost model
ESG and sustainability
Used oil is hazardous waste under the Hazardous and Other Wastes Rules, 2016. Filtration cuts a number you already report in BRSR.
What it feeds into
- Waste generated. Fewer litres drained is a direct, measurable cut.
- Circularity. Longer oil life is easy to evidence to an auditor.
- Scope 3. Litres not bought times the supplier's cradle to gate carbon figure.
- Energy. Fouled circuits use more energy for the same work.
Inserts become waste too
Inserts are a small fraction of the oil they save, but count them in a published claim. We state expected consumption.
The combined case
A short presentation puts the three cases side by side, with a blank cost model, presented on site at no charge.
