If one’s PC is opened after half a year again to install new hardware, perhaps, one often wonders if the calculator is better designed than a vacuum cleaner. On the one hand, you just imagine the ease when how frequently the room would be cleaned as all the dirt was not collected by the computer. This instead means time-consuming cleaning of the PC interior. In addition, dust in the housing is the main reason for overheating and thus leads to possible unstable operation. While cleaning from time to time, this cannot be prevented, it can significantly reduce the expense A simple and inexpensive solution comes in the form of dust filters, which are placed before the imbibing fan. If these are installed, the entire interior with all its tight corners and the sensitive components are not dusted, but only the filter. DEMCiflex offers a particularly simple retrofit solution that is suitable for 140mm fans in this case. Here, the filter is simply placed on the outside of the housing to the fan opening and held magnetically inside. There are no screws or the like needed, so there are no compatibility restrictions. Since not all fan positions are magnetically attractive, an additional frame is supplied with the delivery and attached at the rear and, in turn, held to the filter. The filter itself consists of a very tightly woven and durable polyester fabric. This special material is also used in hospitals and is used to maintain, for example, operating rooms free of dust. At the same time, the network is well-ventilated and, therefore, only obstructs the airflow at a low rate. This effect can, of course, increase dust, so the filter should be removed and cleaned occasionally. This is from …
