Application of flexible bands in the production of anti-dust filters
Anti-dust (cabin air) filters have become standard fit out of passenger and heavy duty vehicles, they are more and more frequently included in the fit out of construction and agricultural machinery.
Flexible FILTRON anti-dust filters
Location of the filter body usually results from the concepts worked out by the manufacturers of respective vehicles and quite often, due to the complexity of the cabin ventilation system, such filters are installed in narrow and hard to reach places. Such location makes the replacement of the filter difficult, its replacement then requires high manual skills and poses a threat of incidental tearing of the filter or its crushing. Thus, the introduction of a solution that would allow for easy and smooth replacement of filters in hard to reach locations proved a necessity.
As a result of the analysis carried out in WIX-FILTRON, the company made a decision to design and launch the production of flexible anti-dust filters, which, in contrast to the standard filters, are provided with sides made of flexible polyester band joined with the filtration medium by means of the flexible adhesive. Filters manufactured in this technology can be freely deflected (bent) during the installation. Thanks to this solution, the ergonomics of installation of certain types of filters has been significantly improved in dedicated vehicles. Among the filters that were subject to re-designing were the following filters: K 1014, K 1055 (Opel Astra) and K 1147A (Peugeot 407). New make of filters also ensures proper bedding of filters and tightness of the contact surface filter-casing, thus guaranteeing proper air filtering parameters during the filter life.
