Sigrist Design offers two series of silent mixed flow, inline duct fans. These types of fans are the go-to solution where an extremely quiet, easy to install in-line fan is required. This may include:​

  • Libraries,
  • Hospitals,
  • Surgery rooms,
  • Offices,
  • etc.

Both our series sport robust, streamlined design with inbuilt sound insulation and a mixed flow impeller design capable of higher static pressures than standard axial fans.
