Compressed air filter installation sequence

If you are not a professional technician, the installation order of compressed air filters are usually confused, once the order is installed in the wrong order, it affects the clean procedure of filtered air and the service life of the filter element. Therefore, the correct installation order is a prerequisite to ensure that we get high efficiency air gas.

1. Filter precision level:

S-class filter is referred to as oil and water separator, filter efficiency > 99%, can remove liquid water and oil. Installed after the air compressor, for a preliminary oil and water separation.

U-level filter is referred to as pre-filter, which can remove solid particles with a precision of 1μm or more and reach the minimum remaining oil content of only 0.5ppm, with a small amount of nutrients, dust and oil mist. It is used for air compressor and rear cooler after and before the dryer as the second step of filtration and purification.

H-class filter, referred to as activated carbon micro oil mist precision filter ,can filter out oil mist and hydrocarbon as small as 0.01μm, to achieve the minimum residual oil content of only 0.1ppm, remove solid particles, water and oil.

F-class precision filter, referred to as ultra-high efficiency oil filter, can filter out liquid and solid particles as small as 0.01μm, to achieve the minimum residual oil content of only 0.01ppm, and almost all nutrients, dust and oil are removed. It is mainly used as a dust filter for compressed air generated during drying in the dryer, also called a post filter.

2. Installation order:

How to install the correct order of compressed air precision filter grades? Very simple, we can see from the above several levels, compressed air filters and filter cartridges a total of four levels, respectively, S, U, H, F. The installation order of the filter mainly depends on their filtration accuracy, then according to the above level of filtration accuracy, the installation order should be S-U-H-F, do not install the wrong oh.

3. installation location:

Compressed air filter installation is recommended to be installed at the back end of the air compressor and the front and back end of the dryer, generally in accordance with the principle of the first three after one.
