•Basic Filtration &
1. What are the results of that
filter performance related to your lubricating oil?
The effective oil purification should be capable of removing three
1). Solid particulate size between 1 to 3 micron,
2). Dissolved water down to 100 ppm, part per
3). Oxidation by-products which cause high acidity and chemical
changes in the oil
2. If you put in a new filter that
is lower micron size, what will happen to the oil cleanliness?
Answer: Oil cleanliness will improve but dirt
holding capacity will be less. The filter will keep clog up in
a short time. Customer will end up paying more for filter usage
3. What is the different between oil
filtration and oil purification?
Answer: Oil filtration is used
to filter some contaminants in the oil, mostly only solid particle.
When oil filter gets clogged, the filter media is losing its integrity
which allows dirt on the filter surface to migrate through the
purification is designed to completely remove all contamination
and bring the dirty oil back to the new oil condition. Oil purification
will alter the physical and chemical changes in the oil without
depleting the original oil additives.
4. Do you know about OilPure
unique features which other filtration systems can
Answer: At a single pass, OilPure
can remove submicronic particulate, dissolved water and oxidation
by-products. Conventional filter will take vacuum distillation
unit to remove water and series of cartridge filters to remove
submicronic particulate, and yet, are unable to remove oxidation.
5. What is a typical method
to remove oxidation or acidity from oil?
Answer: Years ago, industry used Clay
or Fuller Earth materials to remove oxidation
or acidity from the oil. This method is obsolete
because Clay or Fuller Earth will also strip original oil additives.
Additive is a very complex structure and most of them are polar
compounds. These polar compounds will be attached to Clay or Fuller
Earth during chemical reaction and cause oil additive depletion.
6. How does oil oxidation
affect the equipment and machinery?
Answer: Oxidation cause gummy or
waxy stain on valve surface such as servo valves,
proportional valve etc. and cause valve failure.
Oxidation is a liquid contamination which is part of lubricating
oil. It can not be physically filtered out. Highly oxidized oil
will gradually transform oil additives into sludge
and cause additive depletion. Oxidation occurs
because of high surface temperature in the equipment.
electronically controlled valve run at extremely high speeds which
not only increase surface temperature but also demand high precision
machines in operation. In most electronically controlled valves
such as servo valves, proportional valve, tolerance is about 1
to 2 micron. If your filter can not remove particle less
than 1 to 2 micron size, valves will start wear
7. How can we prevent oil oxidation
in the lubricating system?
Answer: Proactive preventative oil maintenance
program will continuously keep your oil clean at all times and
will not allow oxidation to occur.
8. Do you know what is the root
cause of the machine or equipment failure?
Answer: It is a fact that 80%
of equipment failure or down time or deterioration is caused by
9. What are the costs related
to keeping dirty oil in the lubricating system?
1). Poor quality in product precision such as machined part precision
in machining operation, high precision gap or tolerance in finished
products, poor surface on finished products, customer’s
2) New oil purchasing to replace with new oil,.
3) Equipment failure and downtime cost, poor productivity improvement,
labor cost to repair and change oil.
4) Waste oil disposal cost such as 7 year record keeping in waste
manifest documents to EPA, waste hauling cost, cradle-to-grave
liabilities, deep pocket rule if oil spills in public areas.
10. How can we help you to improve your
lubricating system to increase machine productivity?
Answer: Proactive Oil Maintenance program
can improve hidden productivity that cause equipment repair, production
downtime and production lost etc.
