When do you need to change your air compressor air filter/element?

 The replacement time of the Compressed Air Line Filter needs to be judged by the comprehensive operation status, environmental factors and equipment indications.

1. Direct replacement signal (immediate action)

Differential pressure gauge/differential pressure indicator exceeds the standard

When the pressure loss reaches 0.35 barg, the pointer in the pressure gauge will turn from pointing to the green area to the red area; the Compressed Air Filter 1 Micron element should be replaced in time; the principle of the differential pressure indicator is the same;

If the Compressed Air Desiccant Filter is not equipped with an indicator, the working condition of the filter element needs to be checked regularly.

The color of the filter element becomes obviously darker (such as beige → black gray), and the surface is covered with oil or dust

If the filter material is damaged, deformed or the structure collapses, the filter element or filter needs to be replaced immediately.

Degradation of equipment performance‌

Reduced exhaust volume, weakened power output‌

Frequent warning and shutdown of the compressor (such as "warning for too long shutdown" prompt)

‌

II. Reference for periodic replacement (combined with the environment)

Filter element filtration level and recommended replacement cycle‌

Primary filtration: Filters >5μm particulate impurities, recommended use time is 6000 hours;

High-efficiency filtration: Filters >0.01μm particulate impurities, recommended use time is 6000 hours;

Ultra-high-efficiency filtration: Filters >0.01μm particulate impurities, recommended use time is 6000 hours;

Oil filtration: Removes oil vapor and odor, the residual amount of oil vapor does not exceed 0.003mg/m³, and the recommended use time is 2000-3000 hours;

AR/AAR: Installed behind the adsorption dryer, removes >0.01μm particulate impurities, recommended use time is 4000 hours;

Important reminder‌: It is not advisable to only clean the filter element! High-pressure air gun purging will damage the filter material structure, resulting in filtration failure and accelerated equipment wear. When the filter reaches the end of its life, the filter element assembly must be replaced as a whole.
