There are many forms of compressed air filter level division, the following is mainly introduced in accordance with the application area of classification, generally can be divided into the following four categories.
One, DPC rough compressed air filter referred to as rough filter
Rough compressed air filter is also commonly referred to as the primary filter, mainly installed in the front of the equipment, also known as the pre-filter, used to filter impurities greater than 5μm. So the first level is to filter 5μm as the standard.
Two, DPC main line compressed air filter referred to as the main line filter
Main line compressed air filter, that is, intermediate filters, used to filter the impurities through the primary filter is not filtered out, mainly in the 1 to 10 μm of suspended particles of impurities. The second level of compressed air filter is to filter 1μm as the standard.
Three, DPC de-oil compressed air filter referred to as de-oil filter
This is the third level of filtration, mainly out of compressed air inside the oil mist impurities, filtration precision is generally between 0.3 to 0.001μm, due to the general filters can not be filtered out of the filter, so the use of high-efficiency precision filters to intercept micro-particles less than 1μm, so the compressed air filter. The third level is to filter 0.01μm as the standard.
Four, DPC deodorizing compressed air filter referred to as deodorizing filter ? (Activated carbon filter)
Widely used in medical, food and pharmaceutical industries, this deodorant compressed air filter is installed at the end of the air source, mainly used to adsorb and filter the odor in the compressed air, the accuracy is generally 0.01μm.
