The “TRIPLO” filter is a different design based on the existing filtersystems like cartridge- and bagfilters. The word “TRIPLO” already explains it. The “TRIPLO” filter is one filter with three options: cartridgefilter, bagfilter and basketfilter. Three possible filters in one and the same filterhousing.It is often very difficult to know in advance which of the above filters one needs for a certain job. The “TRIPLO” filter makes it possible to adjust your choice later to a different situation. By simply changing the internals one can get another filter. Sometimes a bag gets blocked too fast and is it better to change to cartridges with a bigger filterarea.Next to the multiple-choice system the “TRIPLO” filter also has a guaranteed sealing for microfiltration, because the fixation of the internals is not connected to the closing of the cover, but by separate mechanism.The cartridgefilter operates up-flow and the particles are kept in the bottomside of the housing. Changing of cartridges is reduced to an easy operation by moving the filterpack upwards on a rod centralised in the middle of the filterhousing. The cartridges are removed to the side by pushing a spring while the filterpack is fixated by a braking mechanism. The basket- and bagfilter works down-flow, so when the filter is changed from cartridge to bag one also has to change the in- and outlet
