Fans D2D133-AB06-31/D2D133-AB06-30 blower

Siemens inverter cooling blower

This 380 V centrifugal blower is built for Siemens inverters that use the D2D133-AB06-31 or D2D133-AB06-30 part numbers. It replaces the large bottom fan that removes heat from high-power components such as the IGBT module. Maintenance teams and system integrators working on industrial drives will find it a direct-fit replacement.

Electrical and mechanical integration

The motor runs on 400 V AC with a 360–480 V range and Y wiring at 50 or 60 Hz. Speed reaches 2500 or 2600 rpm while drawing 120 or 165 W and 0.2 or 0.25 A. It develops 250 or 275 Pa of back pressure and operates down to -25 °C, so it fits existing ducting and mounting points without modification.

Genuine ebm-papst construction

The unit is an original ebm-papst centrifugal fan with curved blades designed for low noise and long service life. Using the authentic part avoids the malfunctions that non-genuine fans can trigger in the inverter. No additional accessories or software are included; the blower itself restores the cooling performance the drive was engineered for.
