Purchase now: Pfannenberg 11667103055 PF 67.000 High Flow Fan
Purchase now: Atlantech Drives provides you the Pfannenberg 11667103055 (Model: PF 67.000), the pinnacle of the 4th Generation Filterfan series. This 230 V AC unit is designed for applications requiring the maximum possible airflow from a standard 291 x 291 mm cutout. With an unimpeded airflow capability of up to 625 m³/h, the PF 67.000 is the go-to solution for cooling high-density drive cabinets (VFDs), welding controllers, and power inverters where thermal loads exceed 1500W.
Maximum Efficiency and Pressure Stability
The 11667103055 distinguishes itself from the PF 66.000 by using a higher-torque motor and an optimized impeller geometry. This allows it to maintain high airflow even against significant static pressure (backpressure) caused by dense component packing or dirty filter mats. It features the patented Click & Fit mounting system for rapid, tool-less installation and comes equipped with a G4 fluted filter mat for IP 54 / NEMA 12 protection.

Maintenance Expert Tips: Managing High-Velocity Airflow
Because the PF 67.000 pulls air with such force, the filter mat loads faster than on smaller fans. Expert Tip: Do not ignore the «High Temp» alarm on your cabinet. With this fan, a clogged filter mat can create a vacuum effect that stresses the fan bearings. We recommend inspecting the filter mat (Part 18611600033) every 4-6 weeks in dusty environments. Ensure the exhaust filter (PFA 60.000) is also clear, as a blocked exhaust will throttle this powerful fan immediately.
Frequently Asked Questions (FAQs)
Q: What is the difference between 11667102055 and 11667103055?
A: They are functionally very similar PF 67.000 models. The «3055» suffix often denotes the latest revision or specific approval set (e.g., cULus listed) for global markets. Always check the specific datasheet for minor revision details.
Q: Can I use a speed controller with this fan?
A: Generally, standard AC fan motors are not designed for variable speed control via voltage chopping, as it can cause overheating. It is better to use a thermostat (ON/OFF control).
