The G2E140-PI51-09 is a high-performance, single-inlet forward-curved centrifugal fan manufactured in Germany. This fan is applicable for heavy-duty thermal management of industrial high-power power electronics, industrial control cabinets, and variable frequency drives (VFDs), resolving extreme heat dissipation challenges within compact or high-density installation spaces.
Natively supports dual-frequency operation at 50Hz and 60Hz
Forward-curved high static pressure directly cools dense heat sources
Dustproof external rotor motor ensures reliable, long-term cabinet cooling
The ebm-papst G2E140-PI51-09 AC centrifugal fan serves as a core functional unit for executing high-efficiency forced-air cooling and eliminating heat accumulation. Specifically engineered to address extreme thermal management challenges within high-density, compact spaces, this centrifugal fan efficiently and continuously extracts and dissipates high heat from power electronics, high-power variable frequency drives (VFDs), and automation control cabinets.
Consequently, it safeguards the temperature stability of the internal environment and thoroughly eradicates system shutdowns or electrical thermal failures triggered by localized overheating. By maintaining a constant, optimal airflow that aligns with designated thermal dissipation curves, the fan effectively prevents the premature aging of sensitive electronic components, indirectly extending the service life of high-value assets within the system and significantly reducing unplanned production downtime caused by thermal overloads.

Industrial VFD & Drive Systems
Specifically embedded inside high-power variable frequency drives (VFDs) or cabinets to implement high-static-pressure forced-air cooling for core heat sources like IGBT modules and brake choppers.
Thermal Power
Used for ventilation and temperature control in heavy-duty power enclosures such as thermal power unit auxiliary control cabinets and feedwater pump VFD cabinets.
Wind Power Converters
Provides anti-vibration, long-lasting forced-air cooling in converter cabinets located within the nacelles of high-power wind turbines.
Metallurgy & Iron/Steel Industry
Provides heat dissipation protection for electrical equipment facing high-dust conditions, such as main steel rolling mill motor control cabinets and blast furnace blower VFD cabinets.
Mining & Hoist Drives
Used for centralized heat dissipation in high-voltage, large-scale explosion-proof VFD speed-regulating cabinets of massive mine hoists and underground main ventilation fans.
Petrochemical & Refining Units
Provides airflow circulation in field auxiliary power distribution rooms and Uninterruptible Power Supply (UPS) cabinets within oil refinery hydrocracking units and ethylene cracking units.
When utilizing the G2E140-PI51-09 centrifugal fan, ensure it is securely mounted within designated ventilation ducts or cabinet slots in strict accordance with OEM guidelines, and precisely matched with a 230VAC power supply. As this fan operates on AC power, it is critical to correctly wire a run capacitor that meets original factory specifications and ensure proper cabinet grounding to comply with UL electrical safety standards.
Furthermore, to safeguard its tens of thousands of hours of fault-free lifespan, regularly clean dust accumulation inside the scroll and on the blades while maintaining an completely unobstructed airflow path; this prevents fan overload or VFD thermal trips caused by blocked air ducts.
The G2E140-PI51-09 is a scroll-type AC centrifugal fan manufactured by ebm-papst, with performance fully compatible with the RF2C-140/059 K313 SF-2336. It incorporates a 140mm scroll housing and a dual ball bearing architecture, achieving an IP44 protection rating to deliver high-static-pressure directional airflow. Featuring excellent dustproof and anti-vibration characteristics, this fan maintains high-speed, long-lasting, and reliable forced-air cooling operations even under sustained heavy loads in harsh industrial environments.
It is a high-performance, single-inlet forward-curved AC centrifugal fan manufactured by ebm-papst in Germany, equipped with a 140mm scroll housing.
What is the primary purpose of the G2E140-PI51-09 centrifugal fan?
It is primarily used for heavy-duty thermal management and forced-air cooling in high-power variable frequency drives (VFDs), power electronics switchgear, and automation control cabinets.
How do you install and mount the G2E140-PI51-09 fan?
It must be securely embedded into the designated ventilation slots or ducts inside the VFD following the equipment manufacturer's guidelines, ensuring the airflow path is completely unobstructed.
What is the IP protection rating of the G2E140-PI51-09?
Its hardware physical protection rating reaches IP44, effectively preventing dust ingress and resisting water splashes from all directions.
Why is the G2E140-PI51-09 better suited for dense cabinet cooling than standard axial fans?
As a forward-curved centrifugal fan, it delivers exceptionally high static pressure, easily overcoming the high resistance generated by dense components to drive cool air directly to the heat sources.
