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.
