Industrial Ventilation & HVAC Solution — ebm-papst D2E146-AP47-C3 | RadiCal Series
Where This Product Is Used
The ebm-papst D2E146-AP47-C3 is a high-performance AC centrifugal fan from the renowned RadiCal series, engineered for demanding industrial and commercial airflow applications. Typical deployment environments include:
- Air Handling Units (AHU) — central HVAC systems in commercial buildings, hospitals, and data centers requiring reliable, continuous airflow.
- Industrial Process Ventilation — manufacturing facilities, chemical plants, and food processing lines where consistent air exchange is critical.
- Control Cabinet & Enclosure Cooling — electrical switchgear rooms and automation panel enclosures requiring forced convection to protect sensitive electronics.
- Refrigeration & Cold Storage — evaporator fan duty in cold rooms and refrigerated display units.
- Telecommunications Infrastructure — base station shelters and server room cooling where compact, high-static-pressure fans are specified.
- OEM Equipment Integration — embedded into industrial dryers, laser systems, medical devices, and test equipment by OEM engineers.

Application-Specific FAQ
Q: Can the D2E146-AP47-C3 be speed-controlled with a standard VFD?
A: The D2E146-AP47-C3 uses an AC induction motor. While VFD control is technically possible, ebm-papst recommends verifying motor winding compatibility and minimum speed limits with their technical datasheet. For variable-speed duty, consider ebm-papst’s EC (electronically commutated) equivalents. Contact us for cross-reference assistance.
Q: What is the direct replacement / cross-reference for this model?
A: The D2E146-AP47-C3 is specific to the ebm-papst D2E146 frame. Common cross-references include other AP-suffix variants in the same series. Confirm voltage and performance curve compatibility before substitution. Our team can assist.
Q: Is this fan suitable for outdoor installation?
A: The motor carries IP44 protection, suitable for splash-proof indoor and sheltered outdoor environments. For fully exposed outdoor duty, specify IP54 or IP55 rated variants.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock or bulk orders, typical lead time is 2–4 weeks depending on supplier availability. Contact us for a firm commitment.
Q: Do you provide a datasheet or dimensional drawing?
A: Yes. Email [email protected] with your part number and we will provide the official ebm-papst datasheet and 2D/3D drawings.
