Oil Filter is one of the essential consumable components used in compressors.
Therefore, you can purchase this product for your Mofidi Compressor.
What Is a Compressor Oil Filter?
The compressor oil filter is one of the most critical consumable components in oil-lubricated compressors, particularly screw compressors and oil-lubricated piston compressors.
The primary function of this filter is to remove solid particles, contaminants, metal debris, and deposits from the oil circulating through the compressor system.
Clean oil provides lubrication, cooling, and sealing within the compressor. The oil filter ensures that this oil reaches sensitive components without harmful impurities.
Importance of the Oil Filter in a Compressor
In oil-injected screw compressors, oil is directly injected into the compression chamber to lubricate the rotors, absorb the heat generated during compression, and seal the clearance between the rotors.
If the oil filter does not function properly, abrasive particles can enter the rotors, bearings, and cylinders, causing premature wear and significantly reducing the service life of the compressor.
Types of Compressor Oil Filters
1. Pleated Oil Filter: The most common type, made from specially treated filter paper with multiple pleats. These pleats increase the filtration area and allow the filter to capture particles as small as approximately 10 microns.
2. Metal Mesh Oil Filter: A washable and reusable type suitable for heavy-duty industrial compressors. It captures larger particles and is often used as a pre-filter.
3. Separator Filter: Although it is sometimes confused with an oil filter, it has a different function. The separator filter is designed to separate oil from the compressed air at the outlet of screw compressors.
Signs of a Faulty Oil Filter
- Increased oil temperature
- Reduced oil pressure
- Abnormal noise
- Reduced compressor efficiency
- Oil contamination in the compressed air outlet
When Should a Compressor Oil Filter Be Replaced?
As a general maintenance practice, the oil filter should be replaced at the same time as the compressor oil.
This interval is typically between 2,000 and 4,000 operating hours, or every 6 to 12 months, depending on the operating environment and workload of the compressor.
In hot, dusty, or highly humid environments, the replacement interval may need to be reduced to approximately 1,000 operating hours.
The Role of the Compressor oil filter in a Compressed Air System
The Mofidi compressor oil filter cleans the circulating oil of metal particles and contaminants, protecting bearings, rotors and moving parts from wear.
When Should You Replace the Compressor oil filter?
- Oil darkening quickly
- Rising oil temperature or temperature alarms
- Reaching the running-hour interval in the manual
- Every oil change
Replace the oil filter together with the oil so the new oil is not contaminated.
Why Quality Matters
Low-quality consumables may cost less up front, but they reduce efficiency, raise energy use and damage main components, costing more in the end. Using the right compressor oil filter for your compressor model extends equipment life and reduces unplanned downtime.
