oil filtration efficiency

There are four main facets that will act on oil filtration, namely, the filter media material & structure, the oil’s viscosity, the fluid flow rates and pressure, the working conditions.

The Oil’s Viscosity
It is widely acknowledged that processing high viscosity oil with fine filter media will be difficult, and since the fluid viscosity varies with oil temperature, we can heat the oil before filtration, so the viscosity will drop and filtration will be easier more efficient. Keep in mind, forcing high viscosity oil to pass an inappropriate filter make get it damaged.

The Fluid Flow Rates And Pressure 

Filters are designed to stand certain pressure, and if the pressure goes too high, it might cause deformation and separation of the filter element pleats. To compromise pressure caused by high speed flow, you can choose large bore and long stroke cartridges that will decompress

The Filter Media Material & Structure
Filter media can be fabric, paper or synthetic, each has it’s speciality. The structure of filter also has a significant impact on oil purification efficiency. A poorly constructed filter is easily damaged and eventually collapse under high speed oil flow.

The Working Conditions

Mechanical vibration and pump pulsations are inevitable part of equipment working. These oscillations can dislocate solid contaminants from the filter element and allow the particles to re enter the oil flow.
