BOGE high-pressure filters are available as pre-filter V and also as microfilter FP or activated carbon filter A. All three filters remove solid particles down to 0.01 microns with a separation of 99.99999% from the compressed air. Highly effective microfibre fleeces have a high capacity to absorb dirt while only a low differential pressure is necessary. A pleated depth filter increases the filter area by a factor of 4.5 compared with conventional elements. The design of the filter housing and the filter element are optimised for the flow to have the lowest possible pressure resistance. The high-pressure filters come in 25 and 50 bar versions.
