What is Secondary Filter? Relatively mechanical secondary HEPA filter can effectively remove the above 10 micron particles. And when the particle size is 5 microns or in sub-micron range, efficient mechanical secondary HEPA filter system will become more expensive and wind resistance will increase significantly. By static electricity in the air filter materials, relatively low energy consumption is the advantage of electrostatic dust removal of secondary HEPA filter. And with external thousands of volts, it will produce ozone due to its composition for polypropylene material which will be easy to abandon treatment. To prevent lung disease, lung cancer, liver cancer and other diseases, the secondary HEPA filter can penetrate the cell and go into the blood stream. Ordinary purification machine adopts filter in the air which is extremely easy to block filter hole. The secondary HEPA filter not only has sterilization effect, but also is difficult to cause secondary pollution.

What is secondary filter? An inspection certificate is a natural Secondary HEPA Filter with adsorption of impurities in the air and other environmental protection function. Besides, during the day, it shows a completely natural texture which will send out a full-bodied natural breath and primitive simplicity feelings. According to the prospective production network analysis, the reason for secondary HEPA filter development mainly has the following two points. At first, secondary HEPA filter belongs to wearing parts which need to change regularly, so in the after-sales market sales of secondary HEPA filter is very big. Secondly, our country automobile industry filter manufacturer is generally small scale with low brand concentration. And the secondary HEPA filter after-sales market competition is intense.

What is secondary filter? Usually secondary HEPA filter can be divided into dry type and wet type. Dry secondary HEPA filter is through a dry filter to isolate the impurities in the air filter. Light vehicles are commonly used in the single stage. Its shape is oval or elliptical and plate type. The filter material with metal or polyurethane is metal or plastic. Under the rated air volume flow, the original filtration efficiency shall be not less than 99.5%. The first level of vortex flow pre-filter is used to filter out bulky particle impurities and the filtration efficiency of secondary HEPA filter is over 80% which is commonly known as the main filter.

What is secondary filter? Then, the Secondary HEPA Filters has bypass valve on the bottom and this is in order to take into account the engine with cold oil viscosity and avoid the condition that secondary HEPA filter is partially blocked with all jams. We can guarantee the device designed by oil flow channel directly. When the secondary HEPA filter is under the pressure of the pump, the by-pass valve cycle will be back to engine oil which can not only get paper filtering effect, but also get original paper filter to filter out the larger particles of impurities. The secondary HEPA filter can bring continuous quadratic wear engine.
