    Description
    Description
    APPLICATION
    • Exhaust ventilation systems for commercial, office and other public or industrial premises with limited installation space.
    • The DuoVent EC fan ensures uninterrupted ventilation operation: if one fan fails, the second fan automatically switches on.
    • The modes are controlled by the controller, which is not included in the delivery set and must be ordered separately.
    • Designed for connection to round air ducts with a diameter of 150 to 400 mm.
    DESIGN
    • The fan casing is made of galvanized sheet steel using heat- and sound-insulation material.
    • The air damper allows adjusting the direction of air flow.
    • Controlled by the air flow.
    • The round connecting spigots are rubber sealed.
    • The hinged cover gives free access to the motors, simplifies installation and maintenance of the fans and ducts without dismantling.
    ELECTRIC MOTORS
    • The unit is equipped with high-efficient electronically commutated (EC) DC motors with mixed-type impellers.
    • These state-of-the-art motors are the most advanced solution in energy efficiency today.
    • The motors are equipped with built-in overheating protection.
    • Ball bearings in the motor ensure long service life (40 000 hours).
    • To achieve accurate performance, low noise levels and safe fan operation, each turbine is dynamically balanced during assembly.
    • The motor ingress protection rating is IP44.
    IMPELLER
    • Thanks to the improved mixed-type impeller, which is a hybrid of axial and centrifugal impeller, the DuoVent EC unit has low power consumption and noise level with high performance.
    • The diffuser, the specially profiled impeller and the directing vanes at the outlet of the fan casing distribute air flow in such a way as to attain the best combination of high performance and high pressure at low noise level.
    CONTROLLER
    • Allows tracking the motor failures and signalling them, as well as automatically switching the unit to work with a functioning motor.
    • The controller is not included in the delivery set and must be ordered separately.
    Controller functions:  
    • Automatic alternation of the active fan with preset switching period.
    • Forced constant operation of the fan A.
    • Forced constant operation of the fan B.
    • Fan alarm. The failed fan is switched off, the second fan is switched on. The controller generates an error signal and corresponding indication.
    • Fan speed control.
    • Boost mode increases the performance of the fan. It is possible to set the time during which the fan will run in this mode.
    • Test mode. Automatic alternation of the active fan with a period from 1 to 12 min.
    • Checking motors at start-up.
    • Possibility of connection to BMS.
    • Possibility of connecting an external 0-10 V sensor.
    • Possibility of connecting external devices (10 V and 24 V).
    MOUNTING
    • The duct fans are intended for mounting to round air ducts.
    • The fans are installed between the air ducts.
    • While mounting the fan provide enough access for servicing and repair operations.
