air conditioning primary filter
air conditioning primary filterThe structure of the air conditioning primary filter is generally divided into a keel frame and frame, the keel frame is characterized by strong and even distribution of filter material, but the production is time-consuming and laborious.The frame skeleton is characterized by easy replacement of filter media, time-saving production, and slightly worse strength than the keel frame. In addition to the outer frame materials such as paper frame, aluminum frame, etc., filter materials such as non-woven fabric, nylon mesh, activated carbon filter material, metal hole mesh, etc., and protective mesh such as double-sided sprayed wire mesh and double-sided galvanized wire mesh, can meet different needs. In terms of the production cost of air conditioning primary filters, galvanized frames are more economical than aluminum frames, the production process of both is the same and the filtration effect is the same, only the outer frame material is different. Therefore, if there are no special requirements for the use environment, it is recommended to use the galvanized frame primary filter. The air conditioning primary filter is a component of the ventilation system, mostly used in clean rooms and for dust removal in electronic and mechanical communication devices. It is the central device of the ventilation system when the filter filters a lot of total powder, the pressure drop is too high, which will make the filter through the air volume becomes small, it will also make the filter parts perforated, so when the filter pressure drops to a certain value, the filter will be scrapped. Therefore, to use the filter, it is important to know the service life of the primary air filter. When the filter is not damaged, most of the service life is judged by the pressure drop. The filter must be checked regularly for damage to the over-plastic mesh, for debris blockage on the inlet surface, and damage to the surface of the filter media; if there is debris blockage on the surface, it should be cleaned; if the surface of the filter media is seriously damaged, it must be replaced with new filter media or a new filter re-installed; when installing the filter, ensure a good seal at the pressure edge with the frame to prevent air leakage; do not use heavy objects to hit the surface of the filter. Do not use heavy objects to hit the surface of the filter, and do not pull the surface of the filter media to ensure that the appearance is beautiful and the structure is strong and durable. |
