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 backward 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 %.
