Brief description of the working principle of compressed air precision filter:

1、The compressed air, which contains dust, oil, rust and water and other harmful substances, enters the first stage of the compressed air filter.

2、When the compressed air passes through the first stage of the cartridge mesh filter core to produce the agglomeration effect, larger particles will be adsorbed on the filter material, and water will condense into larger droplets.

3、When entering the separation chamber, the compressed air slows down, allowing the particles to gather again and the water mist to condense again on a honeycomb-shaped water collector.

4、The water laden with impurity particles flows along the bottom to the drainage device, where it is discharged via 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 enters the second stage filter element after the first stage.

6、When the compressed air passes through the second stage of the fibre filter made of special cotton, thousands of small vortexes will be generated, while the compressed air will be accelerated tens of times, the centre of the vortex is like a tornado, forming a vacuum, the water droplets that have not been filtered out in the first stage of filtration are again gasified, converted and filtered out, at the same time, particles as small as 5 microns are also completely removed by the second stage of the filter.

7、After two stages of filtration to achieve a clean, dry compressed air without dust, rust, oil and water droplets, to protect the normal operation of pneumatic equipment and extend the service life of pneumatic equipment.

Compressed air precision filter performance characteristics:

1、The filter element adopts special anti-leakage technology to ensure the filtration effect;

2、The inner cavity of the filter shell adopts anodic oxidation treatment, and the shell adopts epoxy resin dry powder spraying;

3, the filter element adopts imported borosilicate glass fiber;

4, small diameter of fibres in the equipment and smooth surface;

5, can effectively filter solid impurities and oil mist, and quickly eliminate oil mist.
