Lower noise, higher performance
Centrifugal fans from ebm‑papst

Active PFC (Power Factor Correction) prevents reactive power caused by harmonics, thereby increasing the power factor and thus the efficiency of the electronic device. EC centrifugal fans from ebm‑papst with integrated Active PFC prevent current harmonics from occurring in the first place. How the technology works exactly and how you can protect your application with it:

Application-specific resonances can lead to excessive vibration speeds in certain speed ranges, resulting in premature damage to the bearings. Reinforcing the entire system could remedy this problem, but we rely on our integrated condition monitoring system for automatic resonance detection. It prevents operation at critical speeds, which increases service life and operational safety.

ebm‑papst was one of the first manufacturers to recognize the economic and ecological advantages of EC technology. We launched the world's first EC/DC compact fan back in 1965 – 30 years ahead of all other manufacturers. Our development lead is evident today in the world's largest range of EC fans and motors, such as the DV280 EC external rotor drive.

The constant pursuit of developing the perfect solution for our customers requires experience and expertise. The innovative radial impeller of the RadiPac C, made of high-strength, glass fiber-reinforced composite material, represents the latest generation and embodies the results of the latest aerodynamic findings with state-of-the-art manufacturing capabilities.

At ebm‑papst, we focus on high performance and flawless functionality for every single component. With highly efficient EC motors, intelligent control electronics, and optimized aerodynamics, our fans are perfected down to the last detail—so you can rely on the performance of your ventilation and air-conditioning equipment. We deliver accurate and reliable values by measuring with the utmost precision from the very first to the very last step of development and production – under real-world conditions.

The perfectly coordinated fan system makes incorrect configuration impossible. The effort required for grounding is reduced to a single connection, and shielded cables are not necessary. In addition, motor protection, EMC, and mains filters are already integrated, and output filters are not necessary due to the integrated electronics. For you, this means measured, documented, and guaranteed performance data and proven (certified) compliance with regulations for fan systems. Simple plug & play

Want to drastically reduce noise emissions? You can do so easily with the innovative FlowGrid. The air-inlet guard mounted on the intake side minimizes particularly disturbing low-frequency sounds and ensures whisper-quiet air handling applications. With an optional guard grill, the requirements for accidental contact protection are also met.
