J PurposeThe 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 con-trol 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, 125, 150, 160, 200, 250, 315 mm air ducts.

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

J Motor 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 capaci-ty 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).

J Speed controlThe 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 elec-tric mains frequency enabling compatibility with both 50 Hz and 60 Hz networks.

The fans can be easily combined into a single com-puter-controlled network. Special software allows for precise control over the op-erating parameters of the network units.

J MountingThe 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 ser-vicing and repair operations.Electrical connection and installation must be per-formed in accordance with the instruction manual and the electrical connections diagram applied to the termi-nal box.
