    Description
    Description
    APPLICATION
    • Inline fans for supply and extract ventilation of various commercial and industrial premises requiring powerful air flow.
    • The fans are compatible with Ø 150, 200, 250, 315, 355 and 400 mm air ducts.
    DESIGN
    • The casing is made of polymer (for models 355 and 400, the casing is additionally reinforced with a metal housing).
    • Due to the conically-shaped polymer impeller with specially profiled blades the air stream circular velocity increases, which results in higher air flow and pressure as compared to characteristics of standard axial fans.
    • The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high air flow, increased pressure and low noise.
    • The fan casing is equipped with an airtight terminal box for connection to power mains.
    MOTOR  
    • The units are equipped with highly efficient electronically commutated DC motors. These state-of-the-art motors are the most advanced solution in energy efficiency today. 
    • EC motors are characterised with high performance and optimum control across the entire speed range.
    • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
    SPEED CONTROL  
    • The fan is controlled using a 0-10 V control signal. 
    • When the control signal value changes, the EC fan changes its rotation speed and provides air flow required for the ventilation system.
    • Several fans can be integrated into a single computer-driven control system. Custom designed software provides high accuracy control of the fans integrated into a network. The computer display shows all the system parameters and the operation mode can be set individually for each fan in the network.
    MOUNTING
    • The fans can be mounted at any place and at any angle within the ductwork system.
    • Several fans can be installed in one system in parallel to attain higher air flow or in series to increase operating pressure in the system.
    • The fan casing is equipped with fixing brackets for floor, wall or ceiling mounting.
    • The fans can be mounted using KM-Boost brackets of the appropriate size (purchased separately, available for 355 and 400 models).
