Operating principle

The development of the filter module AF 43 combines the triedand-trusted Filtration Group metal edge filter principle with new technologies. There are three complete series of filter elements available for different areas of application in process technology. The mechanically cleanable Filtration Group metal edge filter elements can be selected specifically to match your process and applications. Combined with the different cleaning mechanisms, they thus achieve optimum filtration results, reduce soiling through solids and secure product quality over a long period.
As the filter medium flows in from the side, the solids and impurities contained in the medium are retained on the surface and scraped off into the cone for discharge. The filtrate leaves the housing via the outlet flange at the bottom of the tank. When the pre-set time or differential pressure for triggering the mechanical cleaning has been reached on the filter control, the mechanical cleaning process is automatically started.

    Performance curves

    AF 43 filter performance curves

    Viscosity in 1 mm²/s
    Viscosity in 33 mm²/s
    Viscosity in 100 mm²/s
    Viscosity in 500 mm²/s

    y = volumetric flow V [l/min]
    x = gap width f [µm]

    The curves represent the volumetric flow through the entire filter system (filter housing including one filter element as an example) and refer to a differential pressure of 0.3 bar. Specific information about process data is essential for reliable operation of automatic filters.

    Important information about the performance curve! This is an example of a filter element of the type AF6016. The number of filter elements can be read from the type number key, see section 6.
