Purchase now: Atlantech Drives provides you the Pfannenberg 11677023055 (Model: PF 67.000 400V), the most powerful fan in the standard range, specifically wound for 400 V / 460 V AC industrial power grids. This unit is designed for heavy industry applications (Steel, Mining, Automotive) where 230V control voltage may not be available or where balancing the load across phases is required. It provides exceptional cooling for high-density Motor Control Centers (MCCs) and large drive suites.
Maximum Airflow with Industrial Voltage
The 11677023055 fits the standard 291 x 291 mm cutout but houses a robust high-voltage motor. It delivers an industry-leading airflow of up to 875 m³/h (60 Hz). The PF 67.000 series is characterized by its high pressure stability, meaning it continues to push air effectively even when the filter mat begins to load with dust, a critical feature for minimizing downtime in dirty environments.

Expert Installation Advice: Wiring High Voltage Fans
When connecting a 400V fan, correct wiring is essential for safety and performance. Expert Tip: This unit typically connects across two phases (L1-L2) of a 400V system (400V 2~). Always verify the wiring diagram inside the fan cover. Do not assume it is a standard 230V connection (L-N). Connecting 400V to a 230V fan is a common error that results in immediate destruction; this specific model is built to handle the higher voltage safely.
Frequently Asked Questions (FAQs)
Q: Can I use this on a 480V US grid?
A: Yes, it is rated for 400-460V ranges. At 460V/60Hz, it will deliver maximum airflow performance (~515 CFM).
Q: Does it have a thermal overload protection?
A: Yes, the motor includes integrated thermal protection. Ideally, it should be protected by an appropriately sized motor circuit breaker in the control panel.
