K-fan centrifugal circular duct fan

  • Airtight casing

  • Integral thermal protection

  • Maintenance-free and reliable

The K series is designed for installation in ducts. All the K-fans have minimum 25mm long spigot connections.

The fans have backward-curved blades and external rotor motors. The K-fan has a fixing bracket together, and screws for mounting the bracket are included to simplify the installation. The FK mounting clamp (accessories) prevents vibration transfer to the duct. The fans can be speed-controlled via a stepless thyristor or a 5-step transformer.

To protect the motor from overheating, the fan is impedance protected. The casing is manufactured from galvanised sheet steel and folded, giving the fan a close to airtight casing. Duct connected outdoor and wet room applications of the fan are possible due to the airtight casing. The K-fans have corrosion class C3.
