Energy efficiency and intelligent control for high-performance ventilation solutions.
The SICFLUX FALCON SFA EC axial fans are designed for applications requiring air movement in ventilation, refrigeration, and air conditioning systems. They feature an ultra-compact housing, direct drive powered by an EC motor, and ball bearings, providing increased durability and performance.
They are suitable for a wide range of applications, including industrial ventilation, commercial and industrial refrigeration, air conditioning, thermal management of electronic components, technology and energy applications—such as data centers and power supplies—automotive ventilation, and OEM solutions, among others.
The SFA EC line models feature axial impellers made from different materials depending on the model, including carbon steel, cast aluminum, and high-strength plastic. The frame and protective grille are made of carbon steel. All models have an IP54 protection rating and Class F insulation, with single-phase and three-phase versions and different supply voltages depending on the model.
The electronically commutated (EC) motor provides high energy efficiency and allows speed control via a control signal, according to the specific characteristics of each model and configuration. Equipment selection should be based on the rated data and parameters specified in the technical tables, also taking the equipment dimensions into account.
