PURPOSE

• 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, 125, 150, 160, 200, 250, 315 mm air ducts.

DESIGN

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

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 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).
