The air compressor air filter effect is poor 

1. The intake without pretreatment, -- -- -- -- -- add profiteer; 

2. The filter aging, -- -- -- -- -- - change the filter element; 

3. Containing air filter can‘t chemical adsorption - stop check; 

4. Traffic more than ratings - changing flow filter; 

5. Of air filter internal short circuit, -- -- -- -- -- to find the reason, symptomatic treatment. 

6. Not to tighten the filter fastening screw, -- -- -- -- -- to tighten the filter; 

7. The filter‘s import and export, -- -- -- -- -- - look for the mark direction again; 

8. The downstream piping is not clean, -- -- -- -- -- - flushing downstream piping; 

9. Use some residual pollutants, -- -- -- -- -- - to remove residual pollutants; 

10. The bypass valve does not matter, -- -- -- -- -- - shut the bypass valve. 

Air compressor air filter pressure drop increases: 

1. Core plug or adsorption quantity is too large, -- -- -- -- -- change the filter; 

2. The inlet load of impurities, preprocessing, -- -- -- -- -- - 

3. The filter installation is not level, -- -- -- -- -- -. 

4. Water filter cartridge, -- -- -- -- -- - find out why, row over water; 

5. Automatic drainage device failure, -- -- -- -- -- -- -- adjust to repair or change drainage; 

Air compressor air filter does not work 

1. The inlet and the outlet valve is not opened, -- -- -- -- -- -- -- to open the valve; 

2. The filter serious congestion, -- -- -- -- -- - change the filter element; 

3. The filter is damaged, -- -- -- -- -- -- -- change the filter; 

4. Piping congestion, -- -- -- -- -- -- -- repair with pig.
