Another one of electronic industry air filters features is wide varieties. The self-cleaning filter general equipment commonly uses is a type of electronic industry air filters which appeared in the 1970s, an American company first introduced this filter. In the late 1980s, this kind of filter with complete sets of equipment came into China market. At present, about dozens of domestic enterprises begin manufacturing this kind of filter.
The unique structure of the filter is also one of electronic industry air Filters features. Their filtration components have tubular rigidity and internal filtering material is synthesis of filter paper. It is equipped with self-cleaning counter blowing system including self-cleaning nozzle, the blowpipe, gas storage bag, cartridge filters, etc. Control system includes the programmable controller (PLC), diaphragm solenoid valve, differential pressure transmitter, differential pressure sensor, LCD screen and other accessories. Self-cleaning system is controlled by computer program which is based on differential pressure exceeding a certain value. The self-cleaning counter blowing mode instructions are the differential self-cleaning modes. When the current differential pressure exceeds the alarm value automatically controlled by computer, the electronic industry air filters can adjust the pulse width for continuous automatic counter blowing interval. Also it can be consecrated back into the manual mode until the pressure difference keep within the prescribed scope. Self-cleaning filter in the normal range of resistance is generally set between 400-700pa and alarm resistance is commonly 800-1000pa. Usually the end resistance is set 1200-1500pa. Low resistance values of self-cleaning mean consuming more counter blowing gas to promote diaphragm solenoid valve frequent action and decrease the life of the valve cartridge.
In addition, the electronic industry Air filter can't hold a wind deflector, because filter is not so strong. In the real world, there have been many accidents because of the wind deflector fault or design error that people make a fan blowing straight filter and lead to filter abnormal damage.
