For a reputable German armature manufacturer the high content of oil and chips in his dissolvent cleaning system was a big problem. For the filtration of high chips content in closed dissolvent cleaning systems usually strainers, filter bags or cyclone filters are used. The disadvantages are a high consumption of filter bags, a not acceptable drying time of the chips as well as required interruptions of the cleaning process. The results are high operating costs and emissions of the machine. The remedy was found with a dissolvent cleaning system with an innovative filter system.
Due to the load-chips up to 10 kg per charge be employed a metal edge filter with a filter fineness of 200μm.
