Purchase now: Atlantech Drives provides you the Pfannenberg 11822101055 (Model: PFA 20.000), the dedicated Exhaust Filter designed to complete the airflow circuit for the PF 22.000 Filterfan series. In any enclosure cooling strategy, the exhaust path is critical. The PFA 20.000 allows heated air to exit the cabinet while maintaining an IP 54 / NEMA Type 12 barrier against dust and moisture ingress, ensuring your control panel remains clean and cool.
Technical Specifications and Compact Design
The 11822101055 fits the compact 125 x 125 mm cutout, making it suitable for smaller control boxes or decentralized I/O cabinets. It features Pfannenberg’s patented Click & Fit mounting system, which uses high-tension corner snaps to secure the unit into the enclosure wall (thickness 1-4mm) without screws. The unit includes a G4 fluted filter mat, which provides a 300% larger surface area than flat foam, reducing airflow resistance and extending service life.

Expert Installation Advice: The «Cross-Flow» Technique
For small cabinets, establishing good airflow is difficult due to component density. Expert Tip: Install the PF 22.000 intake fan at the bottom of one side wall, and install this PFA 20.000 exhaust filter at the top of the opposite side wall. This «Cross-Flow» configuration forces the cool air to travel diagonally through the entire width of the cabinet, cooling power supplies and relays that might otherwise be bypassed in a same-wall installation.
