How to choose precision filter for air compressor

As we all know, the compressed air that has not passed through the post-processing equipment of the air compressor cannot be used directly, because the compressed air contains moisture, oil and dust. Compressed air dryer is the most economical and effective water removal equipment, but the removal of oil and dust must rely on the precision filter of the air compressor to complete. What are the precision filters of the air compressor? How should I choose?

Common air compressor precision filters include oil removal water filter (DF9), oil removal filter (DF7), dust removal filter (DF5), high efficiency oil removal filter (DF3), oil removal and deodorization filter (DF1).

According to the temperament requirements of different enterprises, we select the appropriate precision filter for installation.

1. Low-demand gas-consuming industries, such as construction, sandblasting, stamping and other industries, only need to install oil-removing water filter (DF9) and oil-removing filter (DF7).

2. General requirements for gas-using industries (temperament requirements: particles: 1 micron; oil: 1ppm; moisture: dew point 0-10°C), such as ordinary textiles, metal products, pneumatic machinery and other industries, when installing freeze drying In the case of a machine, install a degreasing water filter (DF9) and a degreasing filter (DF7).

3. Typical configuration for gas industry (temperament requirements: particle content: 0.01 microns; oil content: 0.01 ppm; moisture content: dew point 0-10 ° C), such as precision machinery, electronics industry, powder transportation and other industries, in the installation of refrigeration In the case of a type dryer, install an oil-removing water filter (DF9), an oil-removing filter (DF7), a dust-removing filter (DF5), and a high-efficiency oil-removing filter (DF3).

4. Oil-free gas industry (temperament requirements: particles: 0.01 micron; oil: 0.001ppm; moisture: dew point 0-10°C), such as food industry, pharmaceutical industry, bioengineering, chemical analysis and other industries, in the installation In the case of a freeze dryer, install an oil-removing water filter (DF9), an oil-removing filter (DF7), a dust-removing filter (DF5), a high-efficiency oil-removing filter (DF3), and an oil-removing and deodorizing filter (DF1) .

5. Ultra-dry and clean gas industry (temperament requirements: particles: 0.01 micron; oil: 0.001ppm; moisture: dew point 0-40°C), such as lithium battery industry, advanced spraying, precision machinery and other industries, in the installation of adsorption type In the case of a dryer, install a multi-channel oil removal water filter (DF9), oil removal filter (DF7), dust removal filter (DF5), oil removal and mist removal filter (DF3), oil removal and deodorization filter (DF1 ).
