    Description
    Description
    APPLICATIONS
    • Combined supply and exhaust ventilation systems for various premises where high air flow at relatively low system resistance is required.
    • OV EC fans can be used for the direct air exhaust or pressurization in smoke ventilation systems.
    • OV EC fan are suitable for outdoor wall mounting.
    DESIGN
    • The fan casing and the impeller are made of steel with polymeric coating.
    • OV EC fan terminal box is equipped with a cable for remote connection.
    MOTOR
    • The units are equipped with highly efficient electronically commutated EC motors.
    • As of today, such motor type is the most advanced solution for energy saving.
    • EC motors are featured by high performance and the best speed controllable range.
    • Ball bearings in the motor provide long service life designed for at least 40000 hours.
    • Motor protection rating IP55.
    SPEED CONTROL
    • The fan is controlled with the external control signal 0-10 V (air flow control as a function of temperature, pressure, smoke conditions and other parameters).
    • Should the control value get changed, the EC motor adjusts its speed and the fan boosts as much air flow to the ventilation system as required.
    MOUNTING
    • Fan is installed on the wall surface by means of a square mounting plate.
    • The fan is powered through the external remote terminal box.
    • Power supply and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
