Purpose-built industrial cooling
This ebm-papst centrifugal fan is engineered for Vacon inverter enclosures and similar 48 VDC equipment racks. It targets system integrators and maintenance teams who need a direct replacement blower that matches the original motor specifications exactly.
48 VDC nominal with 36–57 V operating range
The motor draws 2.8 A at 105 W and runs at 1780 rpm on a 133 mm impeller. Voltage tolerance is the critical parameter; the unit will not start reliably outside the stated window and must be paired with a supply that stays within it.
External-rotor motor aids thermal management
The rotor sits inside the impeller so airflow passes directly over the windings, keeping temperatures low at the 6 °C maximum ambient rating. Speed is fully controllable via analog or serial interface, allowing acoustic and power optimisation without extra hardware.

Questions about this item
What airflow does the 105 W motor deliver inside a Vacon inverter?
The centrifugal impeller moves up to 35,000 m³/h of air through the inverter enclosure at 1,780 rpm.
What voltage range does the 48 V input actually accept?
The fan runs from 36 to 57 VDC, so a regulated 48 V rail or a battery string within that window is required.
What mounting holes does the 133 mm blade housing use?
The steel-plate housing follows the standard ebm-papst centrifugal footprint for direct bolting to the inverter chassis.
