Purchase now: Pfannenberg 11822151055 IP55 Exhaust Filter
Purchase now: Atlantech Drives provides you the Pfannenberg 11822151055 (Model: PFA 20.000 IP 55), a specialized High-Protection Exhaust Filter designed for harsh industrial environments. While the standard PFA 20.000 offers IP 54 protection, this «15» variant is upgraded to IP 55 / NEMA Type 12 specifications. It is the mandatory exhaust component for enclosures located in areas with high levels of fine dust, oil mist, or where equipment is subject to low-pressure water jets (washdown zones).
Superior Z-Line Filtration Technology
The 11822151055 fits the compact 125 x 125 mm cutout but distinguishes itself with its internal media. Instead of the standard G4 mat, it comes pre-equipped with a Z-Line Filter (IP 55). This dense, pleated media captures finer particles and provides a tighter seal against moisture ingress. It features Pfannenberg’s patented Click & Fit mounting system for tool-less installation into sheet metal walls (1-4mm thick).

Maintenance Expert Tips: Pressure Drop Awareness
The IP 55 protection comes at a cost: higher air resistance. Expert Tip: When using this IP 55 exhaust filter, ensure your intake fan (e.g., PF 22.000) is also equipped with an IP 55 mat. Be aware that the total airflow of the system will be reduced by approximately 15-20% compared to an IP 54 setup. You must account for this derating when calculating the cooling requirements for your VFDs or heat-generating components.
Frequently Asked Questions (FAQs)
Q: Can I wash the Z-line filter?
A: No. Unlike coarse foam filters, the IP 55 Z-line media structure is damaged by washing. It must be replaced (Part No. 18611600034) to maintain the certified protection rating.
Q: Does it fit the standard hole?
A: Yes, it fits the exact same 125x125mm cutout as the standard PFA 20.000, making it an easy retrofit upgrade for problem cabinets.
