Quiet duct fan QUIET 315 for higher airflow rates

Strong airflow for larger ventilation systems

QUIET 315 is a 2-speed duct in-line fan for supply or extract air in round ducts. It is designed for demanding ventilation solutions where higher airflow, reliable operation, and as quiet performance as possible are important.

Main advantages

• High performance for larger spaces
  At maximum speed, it achieves an airflow of up to 1560 m3/h, making it suitable for larger rooms, workshops, commercial kitchens, and other demanding ventilation systems.
• Quieter operation
  The EPP housing is sound-insulated, and the ball-bearing motor helps reduce vibrations and contributes to smoother operation.
• Adjustment as needed
  A mechanical switch allows 2 fixed speeds, so operation can be adapted to current ventilation needs.
• Reliable for long-term use
  The ball-bearing motor is designed for a longer service life, and the thermal overload protection automatically resets after cooling down.
• Easy duct installation
  The fan is installed directly into round ducting with a sealed connection, without the need for a separate wall bracket.

Installation

The QUIET 315 fan is designed for in-line installation in a 315 mm air duct. Thanks to its in-line mounting, it is connected directly into the duct system, creating a sealed and stable connection. This simplifies installation and allows use in supply or exhaust systems.
