Pfannenberg Outlet filter

The 4th generation of Pfannenberg filterfans combines all the advantages of over 60 years of experience. The use of filterfans is the most efficient and cost-effective way to cool the enclosure at low ambient temperatures. In order to utilise this cost-effective and energy-efficient cooling solution of the outlet filter, the shielding effect of the enclosure housing for EM radiation is reduced by the mounting cut-out. When using the EMC filter fans, this shield is securely closed via a sheet metal grille so that EM radiation is attenuated before entering and leaving the enclosure. Advantages of the series at a glance: - For reliable use in the area of electromagnetic fields (metal shielding) - No reduction in the air volume flow - Proven Pfannenberg filterfan technology - Tool-free installation - Environmentally friendly, as no metallised plastics - Safe contact surface on the mounting cut-out edge - No need for toolsSecure contact surface at the mounting cut-out edge without beryllium copper seal - Secure IP-54 protection thanks to foamed seal and patented 4-corner latching - Simple filter mat change in seconds - Flat construction and neutral design enables perfect machine integration - Attenuation at 30MHz approx. 71 dB - Attenuation at 400MHz approx. 57 dB - Approvals: cURus, EAC.
