Air compressor filter element

The function of the air compressor filter element is to feed the oil containing compressed air generated by the host into the cooler, which is mechanically separated and filtered through the oil and gas filter element. It intercepts and aggregates the oil mist in the gas, forming oil droplets that concentrate at the bottom of the filter element and return to the compressor lubrication system through the return oil pipe, allowing the compressor to discharge purer and higher quality compressed air. The oil and gas separation filter element is a key component that determines the quality of compressed air discharged from the oil injection screw compressor. Under proper installation, use, and maintenance, the quality of compressed air and the lifespan of the filter element can be ensured.

The air compressed from the head of the screw compressor host carries oil droplets of varying sizes. Large oil droplets are easily separated through the oil and gas separation tank, while small oil droplets (suspended) must be filtered through micrometer sized fiberglass filters in the oil and gas separation filter element. The correct selection of fiberglass diameter and thickness is an important factor in ensuring filtration efficiency. After the oil mist is intercepted, diffused, and polymerized by the filter material, small oil droplets quickly aggregate into large oil droplets, which pass through the filter layer under the action of aerodynamics and gravity and settle at the bottom of the filter element. These oils are continuously returned to the lubrication system through the inlet of the return pipe at the bottom of the filter element, allowing the compressor to discharge relatively pure and high-quality compressed air.
