Pfannenberg highlights the unique PF Series Filterfans 4.0, which provide an unrivaled airflow, guarantee Nema Type 12 protection and boasts a 300 percent longer lifetime than conventional filters.
Filterfans 4.0 reach a particularly high airflow and provide an IP 54, Type 12 system of protection with flow optimized fins and rotor blades. The Filterfans 4.0 contain 11 field-proven patented features, including a patented 4-corner fastening system that allows the filter medium to be replaced in seconds.
