Axial fan FFowlet

coolingventilationfor air circulation

Overview
The challenge was to develop a new axial fan with optimum efficiency and minimum noise emission. The FFowlet features a profiled, sickle-shaped blade inspired by the silently beating wing of the owl, delivering efficient air movement with reduced noise. Its compact dimensions suit a variety of installation environments. Available in diameters 500–910 mm, FFowlet achieves volume flows up to 24,500 m³/h and static pressure rises up to 150 Pa.

Product specification
The FFowlet axial fan with ultra-low-noise biomimetic blades is designed for applications with low pressure loss such as agriculture, refrigeration, air conditioning and ventilation. With protection class IP55 and coated blades it is suitable for use in extreme conditions. Available with proven AC technology and ECblue external-rotor technology with integrated controller matched to the fan. The unit provides fully speed-controlled volume flow for high operational flexibility.
