Industrial double inlet centrifugal blower
The Fans D2D146-AF02-14 is a new double inlet centrifugal blower built for industrial HVAC and ventilation systems. It uses an external rotor motor design that integrates the motor within the impeller for compact installation. The unit suits engineers and maintenance teams specifying original ebm-papst components for air-handling equipment.
230 VAC and 400 VAC three-phase operation
At 50 Hz the blower draws 0.93 A at 230 V or 0.54 A at 400 V, consuming 345 W and turning at 2100 rpm. At 60 Hz current rises to 1.06 A at 230 V or 0.61 A at 400 V, power reaches 410 W and speed increases to 2200 rpm. Starting current peaks at 1.75 A and 1.0 A respectively. Minimum back pressure is rated at 200 Pa for 50 Hz and 240 Pa for 60 Hz.
Steel plate housing with wide temperature range
Sturdy steel plate construction supports continuous operation from -25 °C up to 60 °C at 50 Hz and 45 °C at 60 Hz. The compact external rotor motor layout enables forced electronic cooling without a separate scroll housing. This blower is not suited for applications requiring single-phase supply or airflow beyond 35000 m3/h.

Questions about this item
How do I wire the three-phase D2D146-AF02-14 for 400 VAC Y connection?
Connect the three phases to the motor terminals in star (Y) configuration for 400 VAC 50 Hz operation; the motor draws 0.54 A at 2100 rpm and 345 W. Ensure the supply matches 400 VAC three-phase.
What bearing maintenance does the external rotor motor need over time?
The external rotor motor uses sealed bearings lubricated for life; no relubrication is required. Monitor for increased noise or vibration which indicates bearing wear and plan full unit replacement.
At what ambient temperature does the blower reach its thermal limit first during continuous duty?
At 400 VAC 60 Hz the maximum ambient temperature is 45 °C; at 230 VAC 60 Hz it is also 45 °C. Operation above these temperatures risks motor overheating and reduced lifespan.
