If these impurities in the air compressors are not filtered out, they may damage the internal components, causing increased wear, reduced efficiency, and even equipment failure. The function of air filters is in charge of filter air in the air compressor, preventing particles such as dust, dirt, and impurities from entering the compressor. Therefore, it is necessary to replace the air filters regularly. But here comes the question, when should I replace the air filters? And how can I get it down? Don’t worry, keep reading the article and you will find answers in the following content.
5 Factors Affecting Air Filter Replacement
Air compressors are equipped with 3 main essential filters: an oil filter, an air intake filter, and an air/oil separator. Just as the oil in your machine needs regular replacement, so too do these filters to prevent early part failure and oil contamination. It’s standard practice to replace both the air and oil filters every 2000 hours of operation, at the very least. In environments with higher levels of dirt or dust, more frequent filter changes may be necessary. Air/oil separators are generally designed to last for 8000 hours of use. However, certain machines may necessitate more frequent replacements according to the service manual. However, the actual service life of air filters varies, when you are considering getting air filters replaced，5 key factors should be taken into consideration:
1. Air Filter Replacement Reference Indicators
The frequency of replacing the air filter of an air compressor depends on many factors, including the work environment, the workload, and the manufacturer’s recommendations. Generally speaking, the frequency of replacing the air filter should be based on the following points:
2. Operating Environment
If the air compressor is exposed to a harsh environment and is used in a dusty, polluted, or humid environment, the air filter will accumulate dust and impurities faster and need to be replaced more frequently. The recommended replacement interval is every 3 to 6 months. On the opposite, If the compressor is used in a relatively clean environment, the filter life may be longer. Generally, it is recommended to replace it every 6 to 12 months.
3. Workload
The workload of the machinery must be taken into consideration. For air compressors under heavy workloads such as long-term continuous operation or handling a large amount of airflow, the filter should be replaced more frequently, and it is recommended to replace it every 3 to 6 months as well. For compressors with low load or intermittent use, the replacement frequency can be relatively low, half to a whole year will be fine.
4. Accumulated operating time
Some compressors are equipped with a cumulative operating time counter that records the actual operating time of the unit. It is also a scientific method to decide on the replacement of the filter cartridge based on the accumulated operating time. It is usually recommended to change the filter cartridge every 1000 to 2000 hours.
5. Air Filter Brands and Types
Different brands and models of air compressors may have different maintenance requirements. It is recommended to consult the compressor’s user manual or contact the manufacturer for specific replacement recommendations.
Periodic Inspection
Regularly checking the condition of your air filter element is an important way to determine when it is time to replace it. If the filter element appears to be very dirty, clogged, or damaged, it should be replaced immediately, even if it is not yet time for the recommended replacement.
How to Change Air Filters? A Step-by-step Guide
Replacing the air filter itself is easy, but there are still a lot of points to notice. Here are the general steps to take when replacing your air filter:
1. Preparation
Before replacing the air filter element, ensure the compressor is completely switched off and the pressure has been relieved to avoid accidents during operation. Consult the compressor owner’s manual for its location and the removal procedure.
2 . Remove the Filter Element
The air filter element is usually located near the air inlet of the compressor. After locating the filter, remember to use a suitable tool (e.g. screwdriver) to remove the cover or housing that holds the air filter element in place. Remove the cover carefully to avoid damaging the internal components. Also, pay attention to the installation direction of the air cartridge, as the new cartridge needs to be installed in the same direction.
3. Clean the filter element slots
Before installing the new cartridge, check if there is any dust or debris in the cartridge slot. If there is, clean the cartridge slot with a clean cloth or compressed air as contamination left in the air compressor will also reduce the life of the new filter element
4. Installing the new filter element
You need to be careful when choosing a new filter. Before purchasing, check your air compressor model and choose compatible ones. When you have the new air filter, place the new air cartridge into the cartridge slot in the correct orientation. Make sure that the cartridge is fully seated in the slot and that there is nothing loose or shifted.
5. Test & Record the Replacement
After the replacement is complete, restart the compressor to check that the unit is operating properly and to verify that the airflow is smooth. For better maintenance, recording the date the cartridge was replaced is strongly recommended, and set the time for the next replacement according to the manufacturer’s recommendations.
FAQs
Where Should I Place the Filters for My Air Compressor for Clean Air?
The location of the filter affects the filtration effect. Generally, the farther away from the air compressor, the more effective it is to capture more water and impurities in the pipes after cooling. In addition, compressed air filters are installed close to the air-consuming equipment to remove condensed liquids and particles in the pipes again before entering the equipment. If you need to remove water and large particles, you can install a water separator or particle filter before the diverter between the hose reel and the HPLV dripper.
Can a Dirty Air Filter Ruin a Compressor?
Yes, a clogged air filter can’t effectively block dust and debris from entering the system. These impurities can get into the compressor, causing wear and potential damage. It also puts extra strain on the fan, blower motor, and compressor components, making the system work harder and shortening its lifespan.
What Does NTP Stand For In Compressor Air Filter Replacement?
In compressors, NTP stands for National Pipe Thread, a thread standard for connecting pipes and fittings. When you find 1/8″ NTP when installing an air filter or pneumatic accessories, it means you need the matching 1/8″ NTP connector to install it correctly.
Can You Run an Air Compressor without an Air Filter?
Yes, it’s crucial to use an air filter to remove unnecessary particles from the air compressor. Without it, the compressor’s performance and efficiency will be affected. Additionally, the compressor’s lifespan will be greatly shortened, and maintenance costs will rise.
