Time to replace the third filter of the air compressor

The replacement cycle of the “three filters”(air filter, oil filter, oil and gas separator) of the air compressor needs to be comprehensively judged based on the use environment, operating time and equipment type. The following are specific replacement suggestions and maintenance points:

1. Air filter

1. replacement cycle：

• routine environmental: Replace every 1,000 – 2,000 hours.
• harsh environments(such as mines, ceramics factories): It is recommended to shorten it to 500 hours and clean it with compressed air every week.

2. maintenance recommendations：

• Regularly check the intake expansion pipe for damage or leakage of air.
• During cleaning, dust is blown from the inside out, and the air pressure is controlled below 0.2-0.3MPa.

2. Oil filter

1. replacement cycle：

• first run: Replace after 500 hours.
• routine environmental: Replace every 2,000 – 3,000 hours.
• harsh environments: Need to shorten the replacement cycle.

2. maintenance recommendations：

• Check the performance of the differential pressure transmitter before replacing it.
• The new filter element sealing ring needs to be oiled and avoid excessive pre-tightening after manual tightening.

3. Oil and gas separator

1. replacement cycle：

• routine environmental: 3000-4000 hours, or replace when the pressure difference exceeds 0.1MPa.
• harsh environments: Need to shorten the replacement cycle.

2. maintenance recommendations：

• Check whether the gasket contains a conductive core to prevent static electricity from accumulating.
• When installing, ensure that the return pipe is centered 2 – 4 mm away from the bottom of the filter element.

4. Lubricating oil

1. replacement cycle：

• first run: Replace after 500 hours.
• routine environmental: Replace every 4,000 – 8,000 hours.
• harsh environments: Need to shorten the replacement cycle.

2. maintenance recommendations：

• Drain condensate regularly (once a week, once 2-3 days in a high temperature and high humidity environment).
• It is strictly prohibited to mix different brands of lubricants.

V. Impact of environmental factors

• dusty environments: Air filters need to be cleaned or replaced frequently.
• high temperature and high humidity: Lubricating oil is easy to emulsify and needs to be shortened.
• corrosive gases: Check the filter element for corrosion and replace it in advance if necessary.

6. Safety operation specifications

1. Preparation before replacement：

• Cut off the power and put a tag on the lock.
• Release the pressure to zero and verify that there is no residual pressure.

2. installation considerations：

• Ensure that the filter element is tightly sealed to avoid leaks.
• Check whether each connecting pipe is loose or leaking.

By following the above maintenance recommendations, you can ensure efficient operation of the air compressor and extend equipment life. It is recommended to refer to the equipment manual or consult the manufacturer’s technical staff to develop a personalized maintenance plan.
