Common Fault Causes and Solutions for Air Compressor Air Filters
The air filter is an indispensable device on medium conveying pipelines.
The air filter installed on an air compressor ensures the quality of intake air under special operating conditions and meets strict air quality requirements in certain industrial sectors.
Therefore, the performance of the air filter directly determines the quality of compressed air.
This article briefly introduces common faults and corresponding solutions for air compressor air filters:
Poor Filtration Performance of Air Compressor Air Filter
No pre-treatment for intake air — Install a pre-filter
Aged filter element — Replace the filter element
Air contains chemical substances that cannot be adsorbed by the filter element — Shut down the unit for inspection
Actual flow exceeds rated value — Replace with a higher-flow filter
Air flow short-circuit occurs inside the filter — Locate the root cause and carry out targeted treatment
Filter element fastening screws are loose — Tighten the filter element
Filter inlet and outlet connections are reversed — Reconnect according to directional markings
Downstream pipeline is contaminated — Flush the downstream pipeline
Residual contaminants exist at consumption points — Remove residual contaminants
Bypass valve is not fully closed — Tighten and fully close the bypass valve
Increased Pressure Drop across Air Compressor Air Filter
Clogged filter element or excessive adsorbed contaminants — Replace the filter element
Heavy impurity load in intake air — Implement air pre-treatment
Filter installed unevenly — Reinstall the filter horizontally
Water accumulation inside the filter cartridge — Identify the cause and drain accumulated water
Automatic drain malfunction — Adjust, repair or replace the drain valve
Air Compressor Air Filter Fails to Operate
Inlet and outlet valves remain closed — Open the valves
Severe clogging of filter element — Replace the filter element
Damaged filter assembly — Replace the filter
Blocked piping — Repair the piping
