Filtration Fact

Properly sized, installed, and maintained hydraulic filtration plays a key role in machine preventative maintenance planning.
The function of a filter is to clean oil, but the purpose is to reduce operating costs.
Additives in hydraulic fluid are generally less than 1 micron and are unaffected by standard filtration methods.
New fluid is not necessarily clean fluid. Typically, new fluid right out of the drum is not fit for use in hydraulic or lubrication systems.
Most system ingression enters a system through the old-style reservoir breather caps and the cylinder rod glands.
System Contamination Warning Signals.
- Solenoid burn-out.
- Valve spool decentering, leakage, “chattering”.
- Pump failure, loss of flow, frequent replacement.
- Cylinder leakage, scoring.
- Increased servo hysteresis.
A simple ‘crackle test’ will tell you if there is free water in your fluid. Apply a flame under the container. If bubbles rise and ‘crackle’ from the point of applied heat, free water is present in the fluid.
Hydraulic fluids have the ability to ‘hold’ more water as temperature increases. A cloudy fluid may become clearer as a system heats up.
Absorption filter elements have optimum performance in low flow and low viscosity applications.
Free water is heavier than oil, thus it will settle to the bottom of the reservoir where much of it can be easily removed by opening the drain valve.
The cleanliness level of a system is directly proportional to the flow rate over the system filters.
Most machine and hydraulic component manufacturers specify a target ISO cleanliness level to equipment in order to achieve optimal performance standards.

Product Advantage

✔	Better component protection and longer system service life due to improved separation capacity (with filter ratings 3 and 5 μm).
✔	Longer element service life and lower operating costs due to particularly low pressure losses across the element and increase in the contamination retention capacity by up to 30%.
✔	Savings in storage costs, because the filter elements can be used universall.
✔	Reduced shipping and waste disposal costs due to weight reduction by up to 30%.
✔	High operational reliability, because the sensitive filter mesh pack is protected against direct fluid flows and pulsation.
✔	Low energy consumption, because due the uniform distribution of the fluid (diffusor effect), a particularly low Δp is achieved across the element.
✔	Compatibility with a wide range of hydraulic fluids and operating temperatures and high strength pack for support and fatigue resistance.

Filtration - Why?

Right from the beginning, there is contamination in a new hydraulic system, which reduces the service life of the system and its components such as valves and cylinders without any or with inadequate filtration. This built-in dirt is created during the manufacturing of the components and mainly consists of coarse particles. In addition to the contamination that arises during operation of the system, e.g. abrasive wear, dirt particles can also get into the system when it is filled with hydraulic oil. This is called ingress contamination.

Choosing the right filter contributes significantly to reducing contamination in the hydraulic system and minimize the wear of the components and thus extend the service life of the machine. This will prevent production downtime, lower the overall production costs and ensuring efficient operation even after many years.

Contamination Causes Most Hydraulic Failures

The experience of designers and users of hydraulic and lube oil systems has verified the following fact: over 85% of all system failures are a direct result of contamination! The cost due to contamination is staggering, resulting from:
	• Loss of production (downtime) • Component replacement costs • Frequent fluid replacement • Costly disposal • Increased overall maintenance costs • Increased scrap rate

Generated Contamination

Abrasive Wear - Hard particles bridging two moving surfaces, scraping one or both.	Adhesive Wear - Loss of oil film allows metal to metal contact between moving surfaces.	Erosive Wear - Fine particles in a high speed stream of fluid eat away a metering edge or critical surface.
Fatigue Wear - Particles bridging a clearance cause a surface stress riser that expands into a spall due to repeated stressing of the damaged area	Corrosive Wear - Water or chemical contamination in the fluid causes rust or a chemical reaction that degrades a surface.	Cavitation Wear - Restricted inlet flow to pump causes fluid voids that implode causing shocks that break away critical surface material.
