'The 4th generation of Pfannenberg filter fans combines all the advantages of over 60 years of experience. The use of filter fans is the most efficient and cost-effective way to cool the control cabinet at low ambient temperatures.
In order to use this cost-effective and energy-efficient cooling solution of the filter fan, the mounting cutout reduces the shielding effect of the control cabinet housing for EM radiation. By using the EMC filter fans, this shield is securely closed with a sheet metal grid, so that EM radiation is attenuated before it enters and exits.
Advantages of the series at a glance:

• For reliable use in the area of electromagnetic fields (metal shielding)
• High air performance (19 - 845 m3/h) in a small space and low energy consumption
• No reduction in the air volume flow
• Proven Pfannenberg filter fan technology
• Tool-free installation
• Environmentally friendly, as no metallized plastics are used
• Safe contact surface on the mounting cutout edge without beryllium copper seal
• Safe IP-54 protection thanks to foamed seal and patented 4-corner locking
• Easy 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'
