Quiet duct fan QUIET 150 with 2 speeds for ventilation

Quiet and reliable duct ventilation

QUIET 150 is a 2-speed axial duct fan for installation in round ducts with a diameter of 150 mm. It is intended for general air supply or extraction where you want effective ventilation without unnecessary noise. Thanks to the sound-insulated EPP housing and the ball-bearing motor, it is an excellent choice for spaces where comfort and reliability matter.

Main benefits

• Quieter operation in practice
  The EPP housing is lightweight, rigid, and naturally thermally and acoustically insulating, so the fan operates more pleasantly and with less disruptive noise.
• Reliable ball-bearing motor
  A ball-bearing motor generally provides a longer service life and less vibration and noise than motors with sleeve bearings.
• Practical 2 speeds
  With a simple mechanical switch, you can select low or high speed depending on the needs of the space and the amount of air you want to move.
• Self-resetting protection
  The thermal overload protection automatically resets after the motor has cooled down, so there is no fuse replacement and no unnecessary servicing.
• Suitable for humid spaces
  Protection IPX4 means resistance to water splashes, so the fan is also suitable for use in bathrooms and other humid spaces.

Installation

The fan is installed directly in the line of a round duct system. The connection to the ducting is tight and sealed, so installation is neat without an additional wall bracket. This type of installation is clear and suitable for standard ventilation runs in apartments and smaller commercial spaces.
