Why Choose the Pfannenberg PFA 20.000 11720001055 Exhaust Filter?
The Pfannenberg PFA 20.000 11720001055 is a compact 4th Generation exhaust filter designed for passive filtered ventilation of electrical enclosures, control cabinets and industrial automation systems. As part of the Pfannenberg PFA 20.000 series, it provides a filtered airflow path and is designed to work with compatible Pfannenberg PF series filter fans for effective enclosure thermal management.
Unlike a powered filter fan, the PFA 20.000 contains no fan motor and requires no electrical supply. Its patented snap-fastening system enables quick screw-free mounting, while the integrated foam seal helps prevent unfiltered air from bypassing the filter. The filter mat can also be exchanged easily during routine maintenance without removing the complete exhaust filter assembly.
Part number 11720001055 is the IP54, RAL 7035 light grey version of the PFA 20.000. Measuring approximately 145 × 145 × 31 mm, it uses a 125 × 125 mm mounting cut-out and is suitable for industrial enclosures requiring compact, reliable passive ventilation with NEMA Type 12 protection.

Reliable Passive Ventilation for Industrial Enclosures
Exhaust filters such as the Pfannenberg PFA 20.000 form an important part of a filtered enclosure cooling system. When paired with a powered filter fan, the exhaust filter provides a controlled path for ventilation air, allowing heat generated by drives, PLCs, power supplies and other electrical components to be transferred from the enclosure to the surrounding environment.
The PFA 20.000 combines compact dimensions with IP54 and NEMA Type 12 protection for industrial cabinet applications. Its passive construction eliminates electrical connections and moving components, while the integrated foam seal, tool-less fastening system and replaceable filter mat simplify installation and ongoing enclosure maintenance.
Typical Applications
- Electrical control cabinets and industrial enclosures.
- PLC and automation control panels.
- Machine control systems and OEM equipment.
- Variable frequency drive and motor control enclosures.
- Power supply and industrial electronics cabinets.
- Packaging and production machinery.
- Enclosures using compatible Pfannenberg PF series filter fans.
- Industrial cabinets requiring passive filtered intake or exhaust ventilation.
