What oils can be filtered by precision oil filter

Time:2025-08-13 11:43:22  Reading volume:

A precision oil filter is a high-efficiency filtration device primarily used to remove impurities, moisture, gas, and fine particles from oil. It is suitable for a variety of industrial and functional oils. The following are common oil types and filtration purposes:


1. Industrial Lubricants


- Applicable Oils: Hydraulic Oil, Gear Oil, Turbine Oil, Compressor Oil, Bearing Oil, etc.

- Filtration Purpose: Removes wear metal particles, dust, and oxidation products to extend equipment life and maintain lubrication performance.


2. Insulating Oil (Power Industry)


- Applicable Oils: Transformer Oil, Switchgear Oil, Capacitor Oil, etc.

- Filtration Purpose: Removes moisture, gas (such as acetylene), and carbon particles to improve dielectric strength and ensure safe operation of power equipment.


3. Fuel and Diesel


- Applicable Oils: Diesel, kerosene, aviation fuel, heavy fuel oil, etc.

- Filtration Purpose: Removes moisture, colloids, and microorganisms (such as bacteria in diesel) to prevent clogging and corrosion in the fuel system.


4. Processing Oils and Coolants


- Applicable Oils: Metalworking fluids (cutting oil, grinding oil), quenching oil, heat treatment oil, etc.

- Filtration Purpose: Separate metal debris and impurities, maintain cooling and lubrication properties, and improve processing accuracy.


5. Bio- and Synthetic Oils


- Applicable Oils: Biodegradable lubricants, synthetic ester oils (such as aviation engine oil).

- Filtration Purpose: Remove contaminants to meet environmental requirements or meet stringent operating conditions such as high temperature and high pressure.


6. Waste Oil Recycling


- Applicable Applications: Recycled waste engine oil, hydraulic oil, etc.

- Filtration Purpose: Recycle oil through multi-stage filtration (such as decolorization and acid removal), reducing waste disposal costs.


7. Other Specialty Fluids


- Applicable Oils: Vacuum pump oil, refrigeration oil, heat transfer oil, etc.

- Filtration Purpose: Maintain oil purity to ensure stable operation of specialty equipment.


Filtration Range


- Standard oil filters: 1-30 microns (suitable for general impurity filtration).

- High-precision oil filters: 0.1-5 microns (e.g., nanofilters, capable of removing trace moisture and extremely fine particles).

- Special configurations: Vacuum dehydration, centrifugal separation, or electrostatic adsorption can be integrated.


Notes

- Oil compatibility: The chemical compatibility (e.g., acidity, alkalinity, and viscosity) of the filter media (e.g., filter element, seal) and the oil must be verified.

- Moisture treatment: Water-containing oils require vacuum dehydration or coalescing separation technology.

- Regular maintenance: replace filter elements promptly to avoid secondary contamination.


The selection of a precision oil filter should be tailored to the oil type, contamination level, and target cleanliness level (e.g., ISO 4406). Please contact us for a customized solution.
