How to Wash the Oil Filter

 

The cleaning method of hydraulic oil filter mainly depends on the material and usage of the filter.

 

01

 

Stainless Steel Oil Filter

Step 1: Immersion Completely immerse the filter element in a dedicated industrial solvent or parts cleaner to dissolve stubborn sludge and carbon deposits.

Step 2: Rinsing Use low-pressure compressed air (recommended below 50 PSI) to thoroughly rinse the filter element from the inside out to remove particles embedded in the mesh.

Step 3: Drying Ensure the filter element is completely dry before installation, either by air drying or by blowing it with low-pressure air.

 

02

 

Fiberglass Oil Filter

Strictly follow the manufacturer's recommended replacement cycle; replace the filter element immediately upon expiration or differential pressure alarm.

 

03

 

Paper oil filter element

Due to their structural characteristics, this material oil filters cannot be cleaned and can only be replaced with new filter cartridges.

Unlike simple strainers, our industrial-grade oil filters operate on the principle of depth filtration. Here’s a breakdown of the process:

1. Multi-Stage Contamination Capture:

• Surface Filtration (Preliminary Stage): As the oil enters the filter housing and passes through the filter media, larger particles (typically above 30-40 microns) are immediately trapped on the outer surface of the filter element. This acts as the first line of defense.
• Depth Filtration (Core Stage): The oil is then forced through the intricate, porous matrix of the filter media—often made of high-grade glass fibers, cellulose, or specialist synthetic materials. This labyrinth of microscopic channels captures fine and ultra-fine particulate contaminants (down to 1 micron or less) throughout the entire depth of the media, not just on the surface. This is critical for protecting sensitive components like servo valves and bearings.

2. The Role of Advanced Filter Media:

The efficiency of depth filtration hinges on the media. We engineer our media with:

• Graded Pore Structure: A carefully controlled density gradient allows for the optimal distribution of contaminant load, maximizing dirt-holding capacity and extending service life.
• High Contaminant Loading Capacity: The robust construction ensures the filter can hold a significant amount of debris without a drastic increase in pressure drop, preventing premature clogging.
• Material Compatibility: Our media is specifically selected for its resistance to chemical degradation from a wide range of process oils and lubricants, ensuring consistent performance and material integrity.

3. Maintaining System Pressure and Flow:

A critical design parameter is the differential pressure (ΔP)—the difference in pressure between the inlet and outlet of the filter. A clean filter has a low ΔP. As the filter collects contaminants, the ΔP gradually increases. Our filters are designed to maintain optimal flow and system pressure within a safe ΔP range until the next scheduled maintenance.

Q1: Are your filter elements compatible with my equipment?

Q2: Are high-precision filter cartridges (e.g., 10 microns) more effective than low-precision ones (e.g., 20 microns)?

A2: Not entirely. The key to choosing the right precision is matching the equipment requirements.

• Excessively high precision can obstruct oil flow, increase the pump's workload, and lead to excessive pressure differentials. Our products cover various precision levels.
• Simply provide your equipment model or original filter cartridge number, and we will recommend the most suitable precision, achieving the optimal balance between filtration effectiveness and equipment performance.

Q3: How to identify a high-quality oil filter?

A3: To determine the quality of a filter, pay attention to the following points:

• Filter Material: High-quality glass fiber or metal mesh with a large filtration area and strong dirt-holding capacity.
• Structural Integrity: A robust support frame and end caps ensure no deformation or cracking under pressure.
• Sealing Performance: High-quality sealing rings ensure no leaks and successful installation on the first try. 

Q4: What is the difference between "absolute accuracy" and "nominal accuracy"?

A4: Both are core indicators for measuring filtration effectiveness:

• Absolute accuracy: refers to the smallest particle size that the filter element can 100% intercept. For example, 10μm absolute accuracy means it can completely capture all particles larger than or equal to 10 micrometers. All the accuracy values ​​we provide are absolute, with proven and reliable performance.
• Nominal accuracy: is only a rough filtration efficiency ratio (e.g., "filters out 98% of particles"), and cannot guarantee complete interception; the protective effect is uncertain.

Q5: Can I replace only the filter element and not the sealing ring?

A5: We strongly advise against this. The sealing ring is crucial for preventing oil leaks. Old sealing rings may be aged or deformed, and reuse can easily lead to leaks. To ensure optimal sealing, all our filter elements come with brand new, original-size sealing rings.
