The D2E146-AP47-C3 is a dual-inlet AC centrifugal blower featuring hot-dip galvanized sheet steel construction and a forward-curved multi-blade impeller for continuous air circulation.
Forward-Curved Dual Inlet
Thermal Overload Protection
Maintenance-Free Bearing Setup
Operating on 230 VAC (50/60 Hz), this heavy-duty unit utilizes a 300-330 W asynchronous external rotor motor (M2E068-EC) with a 8 μF running capacitor to maintain rotational speeds of 2050-2550 RPM. Constructed with hot-dip galvanized sheet steel, the housing and impeller offer robust protection against environmental factors.The unit mounts via integrated flange brackets on the scroll housing, providing ease of installation in high-power frequency converter cooling systems. Safety is ensured through Class F insulation and an IP44 ingress protection rating, alongside a built-in thermal overload protector for motor protection. The 4.7 kg assembly operates with counterclockwise rotation, supported by dual-shielded ball bearings for consistent air delivery in industrial environments.

Automation and Drive Industry
Serves as the core forced-air cooling fan for high-power frequency inverters, rectifiers, and drive cabinets. It rapidly removes massive heat generated by power semiconductors to prevent thermal overload or system shutdowns.
Power and Energy Industry
Utilized for heat dissipation in utility-scale solar photovoltaic (PV) inverters, wind turbine converter cabinets, and commercial battery energy storage system containers, ensuring power conversion stability in harsh outdoor climates.
Rail Transit
Deployed to cool traction converters, auxiliary power supply units, and onboard electronics in subways, metros, and high-speed trains. Its galvanized steel sheet housing offers excellent resistance to mechanical shocks and vibrations.
Metallurgy and Mining
Used in mine ventilation control hubs and heavy-duty electrical rooms situated near smelting furnaces. It circulates and cools the air within sealed control pulpits that must be isolated from hazardous, dusty, or high-temperature ambient environments.
Food and Beverage Processing
Installed in commercial baking ovens, automated food dehydration lines, or the condenser/evaporator refrigeration units of vending machines to accelerate thermal exchange, offering a structural design that is easy to clean and maintain.
When using the D2E146-AP47-C3 blower, it must be operated under the rated 230V AC voltage and correctly wired with the specified external running capacitor (typically 8μF) to prevent motor overheating. Given its IP44 rating and the heavy weight of its forward-curved impeller, the blower must be securely mounted with proper vibration dampers to avoid resonance friction, and filters should be installed at the inlet for dusty environments. Furthermore, regular cleaning of dust buildup on the blades and routine checks for abnormal bearing noise are essential to prevent severe vibrations and equipment failure caused by dynamic imbalance or mechanical jamming.
The D2E146-AP47-C3 is a dual-inlet, forward-curved AC centrifugal fan manufactured by ebm-papst, commonly used in the thermal cooling systems of industrial heavy-duty equipment like inverters.
Which inverter systems primarily utilize the D2E146-AP47-C3?
It serves as a vital thermal cooling spare part for inverters, widely retrofitted inside the air ducts of the ABB ACS800 series and similar medium-to-high power frequency converters.
What materials are used to construct the housing scroll and impeller of the D2E146-AP47-C3?
Both its scroll housing and forward-curved multi-blade impeller are manufactured from high-grade, hot-dip galvanized sheet steel to ensure high structural robustness and anti-rust capability.
What are the motor construction and bearing type of the D2E146-AP47-C3?
It integrates a classic ebm-papst external-rotor asynchronous AC motor, utilizing dual-sealed industrial ball bearings within its rotating mechanism to support continuous duty operation.
What are the ingress protection rating and insulation standard of the D2E146-AP47-C3?
The fan features an IP44 ingress protection enclosure rating, and its motor windings utilize premium Class F heat-resistant insulation materials.
