Pfannenberg PF 22.000 EMC Series Filter Fan , 230V AC, 19W, 178.5 m³/h Unimpeded, 61 m³/h Filtered, , 145x145mm, EMC IP54

The Pfannenberg 11822101055 PF 22.000 EMC Series filter fan is an advanced solution designed for cooling and protecting electrical and automation control cabinets in industrial and laboratory applications. With a robust 230V AC supply and a compact 145 mm by 145 mm face dimension, this fan effectively manages enclosure thermal conditions while safeguarding sensitive electronics from dust, particles, and electromagnetic interference.

This model delivers a high unimpeded airflow of 178.5 m³/h and supports 61 m³/h filtered airflow, making it suitable for environments where both cooling and particulate protection are required. Its integrated EMC shielding, achieved with stainless steel screening, is ideal for installations with stringent electromagnetic compatibility needs, such as factory automation, communications, test benches, and control panels.

The unit features IP54-rated protection, ensuring resistance to dust and water splashes, and a flatpack form factor for installation flexibility - even in compact cabinets. Its quick-change filter mat system and click-fit, hardware-free mounting reduce maintenance time and improve user serviceability. A patented design ensures superior water and dust pre-separation, extending filter life and reducing the need for frequent replacements.

Additional industrial-grade attributes include a noise level of just 44dB, a 19W AC motor for energy-efficient operation, and terminals compatible with up to 2.5 mm² wire for easy integration. The reversible airflow design allows users to either introduce cooled air or extract hot air, and the system is compatible with thermostat control for further energy savings.

Certified to UL508A standards and manufactured in Germany, this EMC filter fan suits a range of industrial settings, such as manufacturing lines, laboratory infrastructure, chemical processing, and high-EMI environments. Its RAL 7035 color and rugged construction meet both aesthetic and durability requirements in modern cabinet installations.

This Pfannenberg solution is part of the innovative fourth-generation filter fan lineup, supporting either new installations or upgrades on control cabinets and compatible with cutouts from earlier product generations. Common applications include automation panels, electronic enclosures, process control cabinets, and systems sensitive to both temperature and electromagnetic noise.
