Description
PURPOSE DESIGN
  • KSB fan design allows to use them in supply and exhaust ventilation systems in premises with high requirements to the noise level and with limited space for mounting.
  • For example, the unit design includes a possibility of space-restricted installation above suspended ceilings.
  • They are designed for mounting into Ø 100-500 mm air ducts.
  • The fan casing is made of aluzinc.
  • For easy installation and operation, the top cover of the fan is secured with a special lock.
  • Warm and sound insulation is made of non-combustible mineral wool 50 mm thick.
  • To ensure better noise absorption, the inner surface of the insulation is made of a perforated metal sheet.
  • The round connecting spigots are rubber sealed.
MOTOR MOUNTING
  • The fans are equipped with asynchronous motors with an external rotor and centrifugal impellers with backward curved blades.
  • The motors are equipped with an integrated overheating protection with automatic restart.
  • The use of ball bearings with specially selected lubricating oil guarantees low noise and makes the fan completely maintenance-free.
  • Inline fans are designed for round air ducts.
  • The fans are installed at an air duct junction.
  • 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.
SPEED CONTROL
  • The control can be either smooth or stepped and carried out with a thyristor or autotransformer regulator.
  • Several fans can be connected to one controller, provided that the total power and operating current do not exceed the nominal parameters of the controller.
