Cleanable filter media are used in processes with high dust concentrations. In order to prevent the filter from being loaded too quickly, surface filtration is implemented in combination with cyclical back-pulse cleaning. The development goal of such media is to minimise dust accumulation for maximum service life. With the filter test systems AFC 131 and AFC 133 for air filter media, corresponding filter tests can be carried out in accordance with various international standards.
The Window PAFWin test stand control and data acquisition and evaluation software, developed by Topas, makes it easy to handle the system and ensures the performance of exact and reproducible tests. The operator is guided through the test and all basic information is available, even in expert mode.
