Industrial AC axial fan for machinery cooling
The M2D068-BFBrand is a new axial fan built around an ebm-papst motor with a 158.5 mm galvanised-steel impeller. It runs on single-phase 400–480 VAC at 50/60 Hz and draws 0.15 A for 44 W input power. Rated IP44 and insulation class F (155 °C), it delivers up to 990 m³/h airflow and 410 Pa static pressure at 2800 RPM while operating from –20 °C to +60 °C.
Replaces worn OEM cooling fans in industrial drives
The unit suits direct replacement of failed M2D068-series fans in Siemens 1PH71 motor assemblies or similar 400 VAC equipment. The jump is worth it when the existing fan has exceeded its 30 000-hour L10 life expectancy at 40 °C or when noise has risen above the rated 75 dB(A). A 2.5 µF/450 V start capacitor is required and the 400 mm TR64 lead matches the original wiring harness.
Limited to fixed-speed AC mains operation
The fan cannot be PWM-controlled or voltage-regulated because it is designed for direct 400–480 VAC line connection. Its 64 mm mounting depth and axial flow pattern restrict use to enclosures that can accommodate straight-through airflow and the specified voltage range. No EC speed-control or GreenTech intelligence features are present in this model.

Questions about this item
What clearance does the 158.5 mm impeller diameter require for mounting?
The impeller diameter is 158.5 mm; allow at least that much free space in the mounting plane plus the motor body depth.
How is the fan wired and which step is often missed?
Connect the 400 mm TR64 plug leads to a 1~400 VAC phase supply and fit the 2.5 µF / 450 V start capacitor; the capacitor is frequently omitted.
When should the fan be replaced based on its rated service life?
At 40 °C ambient the L10 life expectancy is 30000 hours; plan replacement around that interval.
