A well manufactured and specified filter cart, when operated with clean, filtered oil, can produce significant value for your dollar via considerable savings on expensive fluid purchases and less wear and tear on equipment.

Various factors can significantly affect the process of oil filtration, including the oil’s flow and viscosity, the oil system’s pressure, the type of oil used, components that need protection and their cleanliness needs, and the operating environment’s condition.

Besides the physical filter (size, micron rating, media, bypass valve cracking pressure, dirt-holding capacity, and others), the filter cost can also significantly impact oil filtration.

Here, we will talk about some of the main factors that can vastly impact the oil filtration process:

Pressure Drops

The bypass valve spring setting determines the maximum pressure drop across a full-flow filter element. A filter with higher bypass valve cracking pressure is more effective and provides a longer useful lifespan than a lower bypass valve cracking pressure filter.

Oil With Low Temperatures And High Viscosity Start-Ups

Hydraulic and engine filters can experience varying pressure surges, and temperature changes with time. As a result, the increased differential pressures present across the filter element can lead to separation or deformation of the filter media pleats if they are not appropriately designed and supported. This, in turn, will eventually lead to forming an ineffective filter.

Flow Rate Changes

When hydraulic oil undergoes high pressure, some oil compression occurs at around 2 percent per 1000 pounds per square inch psi. If the volume of oil present in the connecting line is 100 cubic inches, and the pressure is 1000 psi, the liquid compression can be closer to 0.5 cubic inches.

When you open a directional control or any other valve downstream under these pressures, the sudden increase in the flow rate can become dramatic. This premature flow rate can be many times the pump output when long stroke cylinders or a large-bore decompress quickly at high pressure.

When you locate the pressure line filters mounted in the return line or at some distance from the pump outlet, these premature flows can produce total collapse or filter media bunching, especially in a poorly made filter.

Mechanical Vibrations And Pump Pulsations

Machinery and other equipment can undergo pump pulsations and operational vibrations from time to time. These conditions can result in dislodging tiny abrasive particles from the filter media, allowing this contamination to make re-entry into the fluid stream.

High Combustion Soot

Diesel engines are well-known for producing carbon soot during their routine combustion process. Soot concentrations that are more than 3.5 percent can result in reducing the effectiveness of the anti-wear additives present in lubricating oil. This, in turn, can lead to enhanced engine wear and tear.
