Purchase now: Pfannenberg 11667022055 3-Phase Filterfan
Purchase now: Atlantech Drives provides you the Pfannenberg 11667022055 (Model: PF 67.000 400V), a heavy-duty industrial Filterfan designed for 3-Phase power applications. While most fans operate on single-phase 230V, this specialized unit is wound for 400 V / 460 V AC (3-Phase). It is the preferred choice for large MCCs (Motor Control Centers) and heavy machinery where 3-phase power is the standard and balancing the load across phases is desirable.
Maximum Airflow with Industrial Reliability
As part of the PF 67.000 series, this is the most powerful fan fitting the standard 291 x 291 mm cutout. It delivers an unimpeded airflow of up to 845 m³/h (50 Hz) to 875 m³/h (60 Hz), significantly higher than its single-phase counterparts. The 3-phase motor offers higher torque and efficiency, allowing it to maintain stable airflow even as the G4 filter mat loads with dust. The unit provides IP 54 / NEMA Type 12 protection, ensuring the cabinet remains sealed against environmental contaminants.

Expert Maintenance Tips: Phase Check
Installing a 3-phase fan requires careful attention to wiring. Expert Tip: Unlike single-phase fans, check the phase rotation if the fan seems to be underperforming. Although axial fans usually spin one way, incorrect wiring or phase loss can cause motor issues. Also, ensure your protection circuit (motor starter or fuses) is sized for the 3-phase inrush current, which differs from standard 230V fans.
Frequently Asked Questions (FAQs)
Q: Can I connect this to 230V single phase?
A: No! This motor requires 3 phases (L1, L2, L3) at 400V. Connecting it to single phase will result in failure to start and motor burnout.
Q: Is it compatible with the PFA 60.000 exhaust filter?
A: Yes, it uses the same housing size. Given the massive airflow (800+ m³/h), we strongly recommend using two PFA 60.000 exhaust filters to minimize backpressure.
