    Description
    Description
    APPLICATION  
    • The KSB 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 100-500 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.
