Series PF provide guaranteed NEMA Type 12 protection, says the manufacturer. 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 fans contain 11 patented features, including a four-corner fastening system that allows the filter medium to be replaced quickly. The fluted filter mat’s folded structure facilitates airflow while the closed-frame design prevents unfiltered air from penetrating the cabinet.Options for other models in the line include NEMA Type 3R/4/4X / IPx6 washdown rainhoods, UV-protected plastic for use in direct sunlight, EMC shielding to attenuate RF signals and exhausting fans for custom applications. The flat profile and uniformly colored design complement modern machines and plants. Eight types with capacities from 17 to 560 cfm are offered.
