AIR FILTER KTM/HUSQVARNA MARCHALD FILTER
Marchald Filters self-extinguishing air filters are entirely handmade in Italy, by a company with over 40 years of experience in the sector, using only the best quality European raw materials, certified class II self-extinguishing. The continuous development of the product in every type of competition has allowed Marchald Filters to create a 2-layer sponge filter with calibrated porosity with unique characteristics, characterized by 3 particular technical solutions that place it at the highest level of efficiency, performance and safety, thus differentiating it from any other air filter on the market. Each filter is composed by assembling only 2 sponge parts (cap and gasket), instead of 3, to decrease the glued filter surface for the benefit of a greater filtering area available; The gluing of the 2 parts takes place vertically, rather than horizontally, to obtain a greater structural rigidity of the product apt to more effectively counteract the lung effect and collapse in case of strong clogging; The external side of the sponge has marked vertical stripes on a part of its thickness to determine a greater impact area of the dust, which is then conveyed and discharged by the stripes towards the lower part of the filter case. This measure allows to delay the premature decay of the performances to the advantage of the engine performances; The quality of the raw materials used for the construction of the archald Filters also allows the use of petrol for their maintenance; however, for ecological reasons, the use of special products readily available on the market is recommended.
