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.
