How often is the air filter of the air compressor replaced?

The replacement cycle of the air filter of the air compressor is subject operating environment, air quality, operating time and other factors, the specific criteria are as follows:

1. regular replacement cycle

1. general Environment:

• 1000-2000 hours(Based on 8 hours of operation per day, about 3-6 months).
• First maintenance: The new machine needs to be replaced after 500 hours of operation.

2. harsh environment:

• mine, ceramic factory, cotton mill such as dust multi-scene, it is recommended every 500 hours replacement.
• Extreme cases: A cement plant due to serious dust, shortened 300 hours replacement.

2. key influencing factors

3. maintenance recommendations

1. regular cleaning:

• weekly purge the dust on the surface of the filter element with 0.2-0.4MPa compressed air.
• Attention: Avoid washing or knocking the filter element to prevent structural damage.

2. Differential pressure monitoring:

• install the differential pressure sensor, and when the differential pressure exceeds 0.05MPa when replacing (the threshold of some models is 0.07MPa).

3. Visual inspection:

• monthly check whether the filter element is deformed or damaged, and whether the interface leaks.

4. Original accessories:

• prioritize the use of the original filter element, and replace the brand to meet the requirements. ISO 12500 standard.

Risk of extended use of 4.

• Decreased efficiency: Blockage leads to a decrease in air intake and an increase in energy consumption by 10%-15%.
• Equipment damage: Dust enters the main engine to wear the bearing. A factory once overhauled the compressor due to the rupture of the filter element.
• Security risks: Overheating may cause the lubricating oil to catch fire (medical air supply system shutdown accident has occurred).

5. industry practice case

summary: It is recommended to flexibly adjust the replacement cycle according to the ambient air quality, and formulate a maintenance plan in combination with differential pressure monitoring and visual inspection. It can be shortened to 500 hours in harsh environment, and the conventional environment does not exceed 2000 hours to ensure the stable operation of the air compressor.
