“Air filter"It is a tool mainly used to collect particulate dust and various suspended solids below 0.5um. It can be used as the end filter of various filtration systems. The "air filter" generally uses superfine glass fiber paper as the filter material, and uses plywood, aluminum foil and other materials to fold as a dividing plate, and then use a new type of polyurethane sealant to seal, and finally use galvanized sheet, stainless steel plate, Made of aluminum alloy profiles as the outer frame.
"Air filter" can be tested by the flame method.
"Air filter" has the characteristics of high filtration efficiency, low resistance and large dust holding capacity.Air filterIt can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments and other industries, and is usually used in the air supply at the end of the air conditioner in the dust-free purification workshop. In general, air and super air filters are mainly used at the end of the clean room.
Among them, the dust particle counter and the 5C aerosol hair device are used for the leak detection of the "air filter. The dust particle counter is mainly used to measure the size and specific number of dust particles per unit volume of air in a clean environment. It can also directly start to detect a clean environment with a cleanliness level of ten to three hundred thousand. It has a smaller volume, relatively light weight, high detection accuracy, functional operation is very simple and clear, and the use of microprocessor control, can be very convenient to store and print the measured results, so that the test clean environment is very convenient. 5C aerosol generator is a kind of particles that can produce consistent and various diameter distribution of aerosol, which can provide enough challenge particles to measure air filtration system when TDA-5C aerosol generator is used in combination with TDA-2G or photometer for aerosol such as TDA-2H.
Most of the leak tests for "air filters" are to put challenge particles in the air.Air filterand then use particle detection instruments on the surface of the air filter and the frame to search for leaks. At the same time, leak testing can try several different ways, each way is suitable for different occasions. Among them, PAO leak detection is a special aerosol photometer test method.
