Quiet duct fan QUIET 125 with bidirectional airflow and EPP housing

Quiet and efficient ventilation for everyday use

QUIET 125 is a 2-speed axial inline duct fan for supply or exhaust air in round ducts. It is designed for bathrooms, kitchens, utility rooms and small commercial spaces where you want reliable ventilation, a low noise level, and simple installation in ductwork.

Main benefits

• Quiet operation
  The sound-insulated EPP housing helps reduce noise and vibrations, making the fan suitable even for spaces where peace and quiet matter.
• Reliable ball-bearing motor
  Ball bearings contribute to a longer service life and smoother operation compared to simpler motors.
• 2 speeds for basic adjustment
  A mechanical switch allows you to switch between two fixed speeds, so you can adjust the airflow to the current needs of the room.
• Practical thermal protection
  The reusable overload protection resets automatically after the motor cools down, which means fewer interventions and no fuse replacement.
• Use in humid spaces
  Protection IPX4 allows use in spaces where moisture and splashing water are present, for example in a bathroom.

Installation

The fan is installed in-line directly into round ducting with a diameter of 125 mm. The connection to the duct system is tight and sealed, so installation is neat and clear, without the need for a special wall bracket. This design is ideal when you want to hide the fan in the ductwork.
