Double inlet centrifugal blower

The ebm-papst D2E146-CD51-23 is a new AC double inlet centrifugal blower with forward curved multi-blade impellers and an external rotor motor. It suits industrial ventilation, air handling units and equipment cooling where a compact, rugged blower is required. The galvanised steel housing is rivet mounted and both volute sides can be opened for maintenance access.

Installation and common issues

The motor is IP44 compliant, permanently sealed and maintenance free with Class B insulation, while ball bearings allow mounting in any orientation. A 4 µF capacitor rated at 450 VDB to the S2 (CE) standard is required for operation. The blower must run at a minimum back pressure of 200 Pa to prevent motor overload. Ambient temperature limits are -25 °C to 50 °C.

Sustained load behaviour

At 230 VAC and 50 Hz the unit draws 1.01 A and consumes 230 W while turning at 1850 min-1. Continuous airflow reaches up to 35000 m3/h under these conditions. The sealed IP44 construction and Class B insulation maintain performance across the full temperature range without degradation during extended operation.

Questions about this item

How do I verify the fan is running correctly after installation?

Measure current draw at the 230 VAC supply; it should read close to 1.01 A and the motor should spin at 1850 rpm.

What comes with the fan and what must I source separately?

The unit includes the double-inlet centrifugal blower with IP44 motor and integrated 4 µF capacitor; you must provide a 230 VAC 50 Hz power connection and suitable ducting.

Which specification should I match to my application when selecting this model?

Choose based on the 230 W power rating, 1850 rpm speed, 200 Pa minimum back-pressure requirement and -25 °C to 50 °C operating temperature range.
