High Performance Air Compressor Pipeline Filter

What is the role of precision filters in air compressor systems?

Precision filters typically have a stainless steel casing. Select different filter elements based on different filter media and design processes to achieve the required effluent quality. It is applied in solid-liquid separation of various suspensions and in the filtration of medicinal liquids with high environmental requirements and filtration accuracy. In an air compressor, it further filters and removes moisture, oil, and other impurities from the compressed air. Precision filters have a wide range of applications and are suitable for industrial fields such as food, chemical, water treatment, pharmaceuticals, and environmental protection.

1. The principle of precision filter is that the precision filter housing is made of high-quality stainless steel, and the filter element is made of formed filter materials such as PP melt blown filter element, polypropylene filter element, wire wound filter element, etc. Under the action of pressure, the original liquid passes through the filter material, the filter residue remains on the filter material, and the filtrate flows out through the filter material, effectively removing impurities, sediments, suspended solids, and bacteria from the water, thus achieving the purpose of filtration.

2. Installation of precision filters

Before installing a precision filter, it is necessary to thoroughly clean the filter housing. When connecting the inlet and outlet of the housing to the filtration system pipeline, pay attention to the direction and confirm that the filter element is in the outer inlet and inner outlet water removal state. After connecting, open the plastic bag at the open end of the filter element, check if the O-ring is intact and in place, then wet the O-ring and filter socket hole with a suitable wetting agent, hold the filter element close to the O-ring end, and vertically insert the filter socket completely into the filter holder socket. After inserting all the filter elements, remove the filter element packaging bag, fasten the pressure plate, install the metal cover, and then open the vent valve on the top of the shell and slightly open the inlet valve. Allow the liquid to enter the housing until it overflows from the vent valve at the top of the housing, at which point close the vent valve. Then slowly adjust the outlet valve and inlet valve until the pressure between the upstream and downstream of the filter drops to the specified value.

3. Maintenance of precision filters

The core component of a precision filter is the filter element, which is a vulnerable component that requires special protection. Long term operation of precision filters can block a certain amount of impurities, which can slow down the working rate. Therefore, it is necessary to clean them regularly and also clean the filter element. During the cleaning process, special attention should be paid to the cleaning of the filter element, avoiding deformation or damage, otherwise it will lead to a decrease in filtration accuracy and fail to meet production requirements. If the filter element is found to be deformed or damaged, it must be replaced immediately.
