Why is it necessary to regularly replace the precision filter element of the air compressor?

In order to obtain stable compressed gas quality，ensure the efficient operation of the air compressor，the air compressor needs regular maintenance。For a long time，people are accustomed to determining whether to replace the filter based on the pressure drop before and after the filter，this seems to save maintenance costs，But we often overlook that， the main reason for installing filters is to remove pollutants from compressed gas，failure to replace beyond the specified deadline will reduce the quality of gas production and affect the lifespan of the air compressor，the replacement frequency of the air compressor filter element should comply with the manufacturer's recommendations，to ensure the acquisition of high-quality gas,extend the service life of the air compressor.

According to the regulations on the air quality level of air compressors,the filter element of the filter needs to be replaced regularly according to the usage of the air compressor,Although the compressed air filter uses high-quality filtering media,but the service life and pollution absorption capacity of the filter medium are limited,We should remember,when the service life of the filter expires,the quality of compressed gas will no longer be guaranteed,Installing an air compressor filter is to obtain compressed gas that meets the required quality standards,therefore, the main reason for replacing the filter is to enable the air compressor to provide stable compressed gas that meets quality requirements.The replacement of the filter element should be based on the manufacturer's instructions,The replacement of the filter element should be based on the manufacturer's instructions,to obtain compressed gas that meets quality requirements.

Many filter housings are equipped with "differential pressure gauges",Usually, these differential pressure gauges are indicators,Cannot be used as an accurate barometer,there are no calibration requirements either,The indicator area representing the differential pressure gauge is composed of green and red colors,When the pointer is in the green area,indicates that the air compressor filter does not need to be replaced,The differential pressure gauge is not a service indicator for the filter,It's not an indicator of air quality either,It only roughly displays the pressure difference,and explain whether the filter has been clogged in advance,Because of the filter fibers in the filter element become brittle gradually during use,Even a small hole can cause the filter medium to be broken,make pollutants enter downstream after filtration,So we cannot simply rely on a differential pressure gauge to determine whether to replace the filter element,Replacement should be carried out according to the manufacturer's recommendations.
