Q1: How to properly clean and maintain the stainless steel mesh oil filter?
A1:（1）Cleaning method: Use an ultrasonic cleaning machine (frequency 40kHz, temperature ≤ 60 ° C) or backwash (pressure ≤ 0.3MPa) to remove deep impurities.
（2）Drying requirements: After cleaning, use oil-free compressed air to blow dry (to avoid oxidation caused by residual water stains).
（3）Taboo: Do not soak in strong acids (such as hydrochloric acid) or strong bases (such as sodium hydroxide) to avoid damaging the surface passivation layer.
Q2: Is this filter suitable for high viscosity oils such as gear oil and asphalt?
A2: Applicability: Supports filtering fluids with dynamic viscosity ≤ 680 cSt (centics) (such as ISO VG 680 gear oil), as the multi-layer mesh structure can withstand pressure differentials ≤ 0.15 MPa.
Temperature limit: Ensure that the oil temperature is ≤ 300 ° C (short-term peak of 400 ° C) to avoid metal fatigue caused by high temperatures.
Scenario case: It has been widely used in hydraulic oil filtration and asphalt conveying systems of mining machinery.
Q3: Is the nominal accuracy of the filter element consistent with the actual filtration effect?
A3: Accuracy definition: The nominal accuracy is based on the beta value test (ISO 16889), for example, β ₅=200 indicates an interception efficiency of ≥ 99.5% for particles ≥ 5 microns.
Influencing factors: Actual efficiency may have a deviation of ± 5% due to fluid cleanliness, flow rate (recommended 1-3 m/s), and temperature fluctuations.
Verification method: On site measurement and calibration can be performed using a particle counter (compliant with ISO 4406 standard).
1. Special design can achieve an effective filtration area of 100%;
2. Each component adopts a seamless fusion method, which solves many problems that originally existed in use and ensures safety;
3. The design adopts a metal folding frame, which can be reused and replaced;
4. The density of the filter material shows an increasing structure, achieving high efficiency, low resistance, and large dust capacity;

Dissolve potassium dichromate or crystals in water to 60 to 80 degrees, and slowly add concentrated sulfuric acid with a concentration of 94% until sufficient. Add slowly and stir. Add up to 1200 milliliters of potassium sulfate or completely dissolve, and the solution will appear dark red in color. At this time, the rate of adding concentrated sulfuric acid can be accelerated until it is completely added. If there are still undissolved crystals after adding concentrated sulfuric acid, they can be heated until dissolved. The function of cleaning solution is to remove general pollutants, grease, and metal particle impurities on the wall of stainless steel filter cartridge, and it can effectively kill the bacteria and microorganisms that grow on the filter cartridge and damage the heat source. If the filter element has been alkaline washed before, the alkaline solution must be washed first, otherwise fatty acids will precipitate and contaminate the filter element.
