Purchase now: Atlantech Drives provides you the Pfannenberg 11643101055 (Model: PF 43.000), a versatile mid-range 230V AC Filterfan designed for industrial enclosures that require more airflow than compact fans but lack the physical space for the large 291mm units. The PF 43.000 strikes the perfect balance, delivering robust cooling performance for medium-sized control panels housing VFDs, contactors, and power supplies.
Technical Specifications and «Click & Fit» Design
The 11643101055 operates at 230 V AC (50/60 Hz) and provides an unimpeded airflow of approximately 270 m³/h. It requires a square cutout of 223 x 223 mm. The unit features Pfannenberg’s patented Click & Fit mounting system, which utilizes reinforced compression springs to snap the unit securely into the sheet metal without screws. This not only speeds up assembly but also ensures a consistent seal (IP 54 / NEMA 12) regardless of the installer’s torque settings.

Expert Installation Advice: Managing «Dead Zones»
The PF 43.000 is often used in cabinets packed with DIN-rail components. Expert Tip: When installing this fan, ensure there is at least 50mm of clearance between the back of the fan motor and the internal components. If cables or wire ducts block the rear of the fan, you create backpressure that drastically reduces the CFM and creates «dead zones» where heat accumulates. Always route cabling around the airflow path.
Frequently Asked Questions (FAQs)
Q: What is the correct exhaust filter for this fan?
A: The matching exhaust filter is the PFA 40.000. It uses the same 223 x 223 mm cutout and G4 filter mat, ensuring balanced pressure within the cabinet.
Q: Can I use this fan in a 60Hz application?
A: Yes, this model is dual-rated for 50Hz and 60Hz. At 60Hz, the fan spins slightly faster, providing slightly more airflow (approx 270 m³/h vs 256 m³/h).
