Purchase now: Pfannenberg 11677103055 PF 67.000 High-Capacity Fan
Purchase now: Atlantech Drives provides you the Pfannenberg 11677103055 (Model: PF 67.000), the flagship 230 V AC Filterfan designed for maximum thermal dissipation performance. When your electrical enclosure houses critical high-load components—such as large Variable Frequency Drives (VFDs) or transformers—standard cooling solutions often fall short. The PF 67.000 is engineered to move massive volumes of air, ensuring that the «Delta T» (temperature difference) inside the cabinet stays within safe limits to prevent thermal shutdown.
Technical Specifications and Pressure Stability
The 11677103055 fits the standard large cutout of 291 x 291 mm, making it fully compatible with existing PF 66.000 installations that require a performance upgrade. It delivers an exceptional unimpeded airflow of up to 625 m³/h (60 Hz). What sets the PF 67.000 apart is its optimized rotor geometry, which allows it to maintain high airflow even against significant static pressure (backpressure) caused by dense component packing or partially loaded filter mats.

Expert Maintenance Tips: The «High-Velocity» Maintenance Schedule
Because the PF 67.000 pulls air with such force, it accumulates dust on the filter mat faster than smaller units. Expert Tip: Do not use a standard maintenance schedule for this unit. We recommend inspecting the filter mat (Part 18611600033) every 4 weeks initially. A clogged mat on a high-static fan like this creates a vacuum effect that can overheat the motor and drastically reduce cooling. Always ensure the exhaust filter (PFA 60.000) is equally clear to prevent backpressure.
Frequently Asked Questions (FAQs)
Q: Can I use a speed controller with this fan?
A: We generally advise against using voltage-chopping speed controllers on these AC motors. The best way to control the fan is ON/OFF via a thermostat (FLZ 520) to save energy and extend bearing life.
Q: Is this the correct replacement for the older Gen 3 fans?
A: Yes, if your old fan used the 291mm cutout, the Gen 4 PF 67.000 is the direct, higher-efficiency replacement.
