As you know, compressed air contains moisture, oil, and dust, so compressed air that has not passed through an air compressor post-treatment device cannot be used as is. Compressed air dryers are the most economical and effective moisture removal equipment, but oil and dust removal must rely on precision filters in air compressors. What is Air Compressor Precision Filter? How should I choose?
Common precision filters for air compressors include water purification filters (DF9), deoiling filters (DF7), dust removal filters (DF5), high-efficiency deoiling filters (DF3), and deoiling and deodorizing filters (DF1). ). Select suitable precision filters for installation according to the temperament requirements of different companies.
1. Low demand gas consuming industries such as construction, sandblasting, stamping and other industries only need to install oil removal water filters (DF9) and oil removal filters (DF7).
2. General requirements for the gas-fired industry (tempering requirements:
particle:
1 micron; oil:
1 ppm; Humidity:
General textiles, metal products, pneumatic machinery, and other industries, etc. when installing freeze-drying. For machines, install a degreasing water filter (DF9) and a degreasing filter (DF7). 3. Typical configurations for the gas industry (tempering requirements:
Particle content:
0.01 micron; oil content:
0.01 ppm; Moisture content:
dew point 0-10℃), etc. B. Precision machinery, electronic industry, powder transportation and other industries in the installation of refrigeration equipment. For the dryer type, install an oil separation filter (DF9), oil separation filter (DF7), dust separation filter (DF5), and high-efficiency oil separation filter (DF3).
4. Oil-free gas industry (Temperature requirements:
particle:
0.01 micron; oil:
0.001ppm; Humidity:
Freeze dryers with a dew point of 0-10°C, such as the food industry, pharmaceutical industry, biotechnology, chemical analysis and other industries, are fitted with an oil-separating water filter (DF9), an oil-repellent filter (DF7 ), dust removal filter (DF5), high-efficiency deoiling filter (DF3), deoiling and deodorizing filter (DF1).
Five. Ultra dry and clean gas industry (temperature requirements:
particle:
0.01 micron; oil:
0.001ppm; Humidity:
dew point 0 ~ 40°C), e.g. B. Lithium battery industry, advanced atomization, precision machinery and other industries, when installing adsorption type dryers, multi-channel oil removal water filter (DF9), oil removal Install the filter (DF7), dust. ● Deoiling filter (DF5), deoiling/mist removal filter (DF3), deoiling/deodorizing filter (DF1).
