Purchase now: Atlantech Drives provides you the Pfannenberg 11666022055 (Model: PF 66.000 IP 55), a specialized version of the industry-standard PF 66.000 Filterfan. While standard models offer IP 54 protection, this unit is engineered for IP 55 (NEMA Type 12) environments. It is the ideal solution for harsh industrial zones where equipment is exposed to water jets, high humidity, or fine dust (e.g., cement plants, flour mills, or washdown areas).
Superior Filtration and Protection
The 11666022055 achieves its higher protection rating through the use of a specialized Z-line filter mat (IP 55) and an enhanced gasket system. Despite the denser filtration media, the powerful 230V motor ensures that the unit still delivers sufficient airflow to cool high-heat loads from VFDs and transformers. It fits the standard 291 x 291 mm cutout, allowing for an easy upgrade from standard IP 54 fans without modifying the sheet metal.

Maintenance Expert Tips: Pressure Drop Management
The trade-off for higher protection (IP 55) is higher static pressure resistance. Expert Tip: The IP 55 mats clog faster than standard G4 mats in dirty environments because they trap finer particles. You must establish a stricter maintenance schedule. Check the mats monthly. If the fan sounds louder or the cabinet temperature rises, the Z-line mat is likely saturated and needs replacement (Part No. 18611600037 for IP 55 mats).
Frequently Asked Questions (FAQs)
Q: Can I wash the IP 55 filter mat?
A: No. The structure of the Z-line IP 55 mat is designed for depth loading and cannot be effectively cleaned by washing. Replacement is mandatory to maintain the IP rating.
Q: Is this fan compatible with the PFA 60.000 exhaust filter?
A: Yes, but to maintain the system’s IP 55 rating, the exhaust filter must also be equipped with an IP 55 mat or be the specific IP 55 version (PN 118602…).
