繁體中文New EC Diagonal Modules: Elevating Filter Fan Performance for Cabinet Cooling
10/11/2025To achieve effective enclosure cooling, the design of filter fans must encompass all their components—grilles, filters, and internal parts alike. ebm-papst’s new EC diagonal modules stand out here: they provide consistently strong air performance, cooling enclosures more evenly and with better energy efficiency than conventional axial fans.
Filter fans are a well-established solution for enclosure cooling, as they allow the use of filtered ambient air, thereby reducing costs associated with external air conditioning systems. The new EC diagonal modules from ebm-papst outperform axial alternatives, boasting easy installation and high energy efficiency. Unlike AC modules, EC versions offer infinite variability and consume less energy, courtesy of efficient brushless motor technology—delivering far greater efficiency at the same air output. Available in sizes 165, 200, and 250, these new modules ensure reliable cooling with minimal noise, while also providing robust protection against dust, dirt, and moisture.
Diagonal fans differ from axial ones in their airflow mechanism: they draw in air axially but use centrifugal force to create a diagonal outflow and higher air compression. Despite this high compression, noise levels remain low. This diagonal airflow ensures the entire enclosure is cooled uniformly, reducing heat buildup in localized areas. Unlike axial fans—whose efficiency drops as resistance increases—diagonal fans maintain consistently high air performance even under higher static back pressure. When paired with filter media and protective grilles, this efficiency translates to longer maintenance intervals. Additionally, the modules’ improved aerodynamics and preguide grille (FlowGrid) further minimize noise.
The modules feature a compact design with a shallow installation depth, enabling quick and simple installation via plug-and-play functionality, regardless of the mounting position. What’s more, they often require less installation space, freeing up more room for electronic components. They can also be integrated on both the suction and discharge sides of enclosures. Leveraging efficient EC technology and a broad voltage range (100V to 240V), these modules are suitable for global use in applications that demand high airflow rates.
