Description
Description
APPLICATION  
  • The KSF K2 EC fans are designed for supply and exhaust ventilation of 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.
  • Compatible with Ø 100-250 mm air ducts.
DESIGN  
  • The fan casing is made of aluzinc.
  • For easy installation and operation, the cover of the fan is secured with a special lock.
  • The casing is heat- and sound-insulated with a 50 mm layer of non-flammable mineral wool.
  • 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  
  • The units feature efficient electronically commutated (EC) direct current motors with an external rotor and centrifugal impellers with forward curved blades.
  • EC motor is free of friction and wear parts such as a commutator and brushes.
  • These components are replaced by a maintenance-free electronic circuit board.
  • EC motors are characterised with high performance and optimum control across the entire speed range.
  • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
INTEGRATED FUNCTIONS AND CONTROL  
  • The fan is controlled with an external control signal 0-10 V (capacity control is performed depending on temperature, pressure, smoke level etc.).
  • The fan has low energy consumption at any speed.
  • Maximum fan speed does not depend on the available current frequency and is suitable for operation both at 50 and 60 Hz.
  • The fans can be connected to centralized computer ventilation control systems.
INSTALLATION  
  • Duct fans are intended for mounting to round air ducts.
  • The fans are installed between the air ducts.
  • In case the fan is mounted on flexible joints, attach the fan to a structural unit by means of supports, suspension links or brackets.
  • The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
  • While mounting the fan provide enough access for servicing and repair operations.
