The patented Herding BETA provides proven Herding technology now for numerous applications in temperature ranges of up to 160°C. Due to the reliable separation, even of finest particles, only a very low residual dust concentration of < 0.5 mg/Am³ remains after filtration. The Herding BETA is a dust Ex zone barrier according to VDI 2263 and has a high chemical and remarkable pH resistance (1-10). Sterilization is possible without any problems. The filter elements are tested at a hundred percent rate and stand out due to the effective product separation on the surface - pure surface filtration with constant operation conditions.
