FTM high pressure filters have been studied to guarantee the lowering of dust during the unloading of the vehicles in the receiving hopper. The modular construction allows the match of several elements in order to guarantee an homogeneous detection of dusts on all the hopper length. The basic unit includes:
a lower element which allows to capture the dusty air right over the hopper protection grill, provided with a speed monitor system in entrance and slide for the re-introduction of the lowered dusts directly into the hopper.
an upper element which contains the straining mass, with the electro valves group, the compressed air tank, the centrifugal fan and an access door for maintenance.
Each filter is provided with an electronic control unit for the automatic cleanness of the arms, by cyclic blowing of counter-current compressed air. Furthermore, spacer elements are available (without straining mass, electro valves and fan), to alternate with the straining units, in order to get efficient solutions with held down investment costs. 13 standard configurations are available for hoppers from 2,0 to 18,0 m. length. The standard construction is made in pre-galvanized steel, but the epoxy varnished option is available too. FTM filters guarantee excellent performances, a very easy maintenance, and they can be provided with a declaration of conformity according to:
94/9/CE – ATEX Instructions, for plants in area 22.
