Common problems and solutions for compressed air filters (filtration efficiency)

Common faults and troubleshooting of air filters: filtration efficiency

1. Add a pre filter for untreated intake air;

2. Filter element aging, replace filter element;

3. The air contains chemicals that cannot be absorbed by the filter element, and should be treated in advance according to the situation;

4. If the flow exceeds the rated value, replace the high flow filter;

5. There is a short circuit in the air flow inside the air filter. Find the cause and take targeted measures;

6. The fastening screws of the filter element are not tightened, tighten the filter element;

7. Reverse the connection of the air filter inlet and outlet, and reconnect it in the marked direction;

8. Unclean downstream pipelines, flush downstream pipelines;

9. Use points with residual pollutants to remove residual pollutants;

10. The bypass valve is not tightly closed. Close the bypass valve tightly.

Common faults and troubleshooting of air filters: The filter does not work due to the following reasons:

1. The inlet and outlet valves are not open, open the valves;

2. The filter element is severely blocked, replace the filter element;

3. Filter damaged, replace filter;

4. Pipeline blockage, repair the piping device.

Common faults and troubleshooting of air filters: increased pressure drop, cause analysis as follows:

1. If the core is blocked or the adsorption capacity is too large, replace the filter element;

2. High load of intake impurities for pre-treatment;

3. Filter cartridge water accumulation, identify the cause, and discharge excess water;

4. Automatic drain failure, adjust, repair or replace the drain;

5. The air filter is not installed horizontally, please reinstall it.

Common faults and troubleshooting of air filters: sudden decrease in flow rate

1. Loose end cap, tighten the end cap;

2. The piping valve is not open, open the valve;

3. Low intake pressure, check the cause and increase the intake pressure;

4. O-ring leakage, replacement;

5. Leakage in piping, repair piping.

Fault and troubleshooting of increased pressure drop in air filters:

1. If the core is blocked or the adsorption capacity is too large, replace the filter element;

2. High load of intake impurities for pre-treatment;

3. Filter cartridge water accumulation, identify the cause, and eliminate water accumulation;

4. Automatic drain failure, adjust, repair or replace the drain;

5. The air filter is not installed horizontally, please reinstall it.

Hazards of Overuse of High Precision Air Filter Core

Function: Remove oil and dust, filter out oil, dust, and liquid water in compressed air; Deodorizing filter element, filtering out oil vapor and other odors in compressed air; Sterilization filter element: filters out bacteria in compressed air.

Material: The oil and dust removal filter elements are made of high-precision fiberglass; The deodorizing filter element is made of activated carbon; The sterilization filter element is made of ultra strong borosilicate glass fiber.

Service life: The design service life of the filter element is usually 1 year. The blocking pressure difference standard for high-efficiency oil removal and dust removal filter elements is usually 0.7 bar.

The hazards of prolonged use: excessive resistance of the filter element, high pressure drop in the pipeline, and increased energy consumption of the unit.
