The filter has two zinc coated steel end caps on both sides, the upper one with a glued cylindrical gasket and the lower one with an attached sealing disk. The reinforced pleated filter media (FA8267) is potted together with the expanded zinc coated steel screens into the caps with polyurethane. The embossed pleating spacers on top of each pleat, and the hot melt fixation on the inside, ensures the uniform shape of the filter media through the filter lifetime. This construction gives a highly active filter surface with a high dust holding capacity and a low pressure drop.
Each filter is tested on size and also visually tested for tightness and complementation. In our laboratory, the tensile strength of un-pleated and pleated media is tested using the dumb-bell shape of each roll. Furthermore, the design of those cartridges is approved through many kinds of examinations, such as the dust holding / pressure drop test and also the rust and extreme condition test
