1. Compressed air containing harmful substances such as dust, oil, rust and moisture enters the first-stage filter device of the compressed air filter.
2. When the compressed air passes through the first-stage cylindrical mesh filter element, a coalescence effect is generated, larger particles will be adsorbed on the filter material, and the water will condense into larger water droplets.
3. When entering the separation chamber, the compressed air speed slows down, causing the particles to gather again, and the water mist condenses again on a honeycomb water collector.
4. The water carrying impurity particles flows along the bottom to the drainage device and is discharged through an automatic or electric drain valve.
5. More than 95% of the water droplets, oil and large particles in the compressed air have been filtered out by the first filter element, and the compressed air after the first-stage filtration enters the second-stage filter element.
6. When the compressed air passes through the second-stage fiber filter made of special cotton, thousands of small vortices will be generated. At the same time, the compressed air will be accelerated dozens of times. The center of the vortex is like a tornado, forming a vacuum state. The water droplets that were not filtered out in the first stage of filtration are gasified, converted, and filtered out again. At the same time, particles as small as 5 microns are also completely removed by the second-stage filter.
7. After two-stage filtration, clean and dry compressed air without dust, rust, oil, or water droplets is obtained, which ensures the normal operation of pneumatic equipment and extends the service life of pneumatic equipment.
