Rotron MAXIAX 3.-3.75 Large Vaneaxial Fans General Large Vaneaxial Information MAXIAX fans provide relatively high flows against high impedance in a compact axial flow package. They operate at high rotational speeds, typically with Hz motors or internal ECDC brushless motors. MAXIAX fans are extremely efficient and highly customizable, allowing for precise airflow design. MAXIAX fans are typically utilized to cool airborne radar and other devices with high power transmitters. They are also employed as evaporator/condenser fans in environmental controls systems and to duct air to various aircraft avionics bays, cockpit displays and cabin compartments. MAXIAX fans are also used extensively in general aviation aircraft, military vehicles and shelters and shipboard applications. They come in a variety of voltages and frequencies and are available with lead wires, terminal blocks and MS connectors. Most units are available with an optional internal Fan Performance Sensor (FPS) or an internal or external Low Speed Warning Device (LSWD).
