VENTS KSB 100 EC Centrifugal inline fan in isolated casing


  • The design of the KSB fans allows to use them in supply and exhaust ventilation systems in premises with high requirements to the noise level, efficiency and fan control and with limited space for mounting.
  • For example, the unit design includes a possibility of space-restricted installation above suspended ceilings. 

  • The KSB EC fans are designed for mounting into Ø 100 mm air ducts.

  • Centrifugal inline fan with capacity up to 280 m³/h in insulated casing.


  • The fan casing is made of galvanized sheet steel using heat- and sound-insulation material.
  • The round connecting spigots are rubber sealed.

  • The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with backward curved blades.

  • These motors currently are the most cutting-edge solution in the field of energy conservation.

  • The use of EC motors allows to reduce the electricity consumption by 35% approximately while providing the high capacity and low noise level.

  • The EC motors are featured with high performance and totally controllable speed range.

  • The high efficiency (up to 90%) is a definite advantage of the EC motors.

  • The motors are equipped with rolling-element bearings that provide a longer operation period (40000 hours).

Speed control

  • The fans are controlled by means of a 0-10 V external control signal while the performance regulation is based on the feedback from the temperature, smoke and other sensors as well as other vital parameter settings.

  • As the control signal changes the EC fan changes speed accordingly to supply the exact air amount required by the ventilation system.

  • The maximum fan speed does not depend on the electric mains frequency enabling compatibility with both 50 Hz and 60 Hz networks.

  • The fans can be easily combined into a single computer-controlled network.

  • Special software allows for precise control over the operating parameters of the network units.


  • The fans are intended for installation in round air ducts. They are installed between the air ducts. 

  • The use of flexible connectors requires fixation of the fan on the building structure by means of supports, mounts or fixing brackets.

  • The fan can be fixed in any position, taking into account the air flow direction indicated by the arrow on the fan casing.

  • While mounting the fan provide enough access for servicing and repair operations.

  • Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box.
