Purchase now: Pfannenberg 11832101055 PFA 30.000 Exhaust Filter
Purchase now: Atlantech Drives provides you the Pfannenberg 11832101055 (Model: PFA 30.000), the dedicated Exhaust Filter designed to complement the PF 32.000 Filterfan series. In a properly designed forced convection system, the exhaust unit is not just a passive grille; it is a critical component for maintaining the NEMA protection rating of the enclosure while allowing heated air to escape with minimal resistance. The PFA 30.000 ensures that your cabinet «breathes» effectively, preventing heat pockets that can derate variable frequency drives (VFDs) and sensitive PLCs.
Technical Specifications and «Click & Fit» Technology
The 11832101055 is finished in standard RAL 7035 (Light Gray) and fits the widely used 177 x 177 mm cutout. It features Pfannenberg’s patented Click & Fit mounting system, which allows for tool-less installation in seconds. The unit comes pre-installed with a G4 fluted filter mat, which offers a 300% larger surface area than flat mats, providing superior dust holding capacity and ensuring that dust does not back-flow into the cabinet when the fans are off.

Expert Installation Advice: Strategic Placement
To maximize the cooling efficiency (Delta T), placement is everything. Expert Tip: Install the intake fan (PF 32.000) in the bottom third of the cabinet door, and install this exhaust filter (PFA 30.000) as high as possible on the door or side wall. This leverages the natural «chimney effect,» where hot air rises. If you place the exhaust filter too low, you risk «short-circuiting» the airflow, where cool air exits before it has a chance to absorb heat from the components.
Frequently Asked Questions (FAQs)
Q: Can I wash the filter mat?
A: We recommend replacing the G4 mat (Part No. 18611600031) rather than washing it. Washing disrupts the fiber structure and reduces the electrostatic efficiency required to trap fine dust particles.
Q: Is this unit compatible with the black fans?
A: Functionally yes, but aesthetically no. For black (RAL 9011) cabinets, you should order the PFA 30.000 Black edition to match the color scheme.
