The Short-Case EC Axial Fan for Ventilation redefines space-efficient air movement, offering powerful performance in a compact form factor critical for tight installations. With diameters ranging from 250mm to 630mm, its shortened casing reduces installation depth by up to 40% compared to standard axial fans, making it ideal for environments with limited clearance . Powered by an EC motor, it delivers energy savings of up to 70% while maintaining airflow rates up to 220 CFM, proving that small size doesn’t compromise efficiency . Compliance with CE LVD 2014/35/EU and EMC 2014/30/EU standards ensures safe integration into European ventilation systems .
The fan’s compact housing features a reinforced steel frame with double flanges, enabling inline installation in ducts, wall openings, or ceiling cavities where traditional fans won’t fit . Its lightweight construction (up to 28.6% lighter than comparable models) simplifies handling during installation .
Capable of operating at any angle (horizontal, vertical, or inverted), this fan adapts to diverse installation requirements from subway tunnels to server rack cooling . The integrated 0-10V control input allows precise speed adjustment, while optional sensors enable automatic modulation based on air quality or temperature.
Designed to function in temperatures ranging from -20°C to 50°C, the fan includes an IP65-rated junction box to protect electronics from moisture and dust . This ruggedness makes it suitable for both indoor and semi-outdoor applications, including parking garages and transit stations.
Installed in subway stations, train tunnels, and bus terminals, where space constraints demand compact ventilation solutions without sacrificing airflow performance.
Mounted in server racks and equipment enclosures, the fan provides targeted cooling for heat-generating electronics, maintaining optimal operating temperatures .
Ideal for upgrading aging ventilation systems in historic buildings or older facilities, where structural limitations prevent installation of larger modern fans.
The short-case design requires as little as 150mm of depth, depending on diameter, making it suitable for tight spaces where standard axial fans cannot be installed .
While centrifugal fans excel in high-pressure systems, this axial fan offers higher airflow per unit size in low-to-medium pressure ducts, making it more energy-efficient for straightforward ventilation paths .
The fan features a plug-and-play design that simplifies setup, though adherence to local electrical codes is recommended. No specialized programming knowledge is needed for basic operation .
