Summary
See more specification See less specification
The Systemair Prio 400 is part of the prioAir series of circular in-line duct fans, with aerodynamically optimised impellers and guide vanes and an integrated external-rotor motor. It delivers up to 4424 m³/h through 400 mm duct with high efficiency, low SFP and a low sound level.
- Airflow up to 4424 m³/h; 400 mm connection (EN 1506 spigots)
- External-rotor AC motor; speed-controllable via stepless thyristor or 5-step transformer
- Aerodynamically optimised impeller and guide vanes; low SFP, high efficiency, low noise
- Airtight sheet-steel casing; IP55 terminal box (outdoor/wet-room capable)
- Integral thermal contacts with manual reset (EN 60335-2-80)
- Installs in any position; FK mounting clamp prevents vibration transfer to the duct
Suitable for
- Duct-mounted extract and supply in commercial and industrial circular duct systems, including outdoor and wet-room duct runs
- Systems where efficiency and low noise matter
Installation
Installs in any position; the FK mounting clamp (accessory) eases installation/removal and prevents vibration transfer. For damp locations a run-on timer is recommended. Should be installed on a suitable circuit by a qualified electrician.

What is the Systemair Prio 400 for?
It's a circular in-line duct fan for 400 mm ducting, for efficient, quiet extract or supply in commercial and industrial circular duct systems, including outdoor and wet-room duct runs.
How much air and what duct size?
Up to 4424 m³/h through 400 mm ducting (EN 1506 spigots).
Can it be speed controlled?
Yes, via a stepless thyristor controller or a 5-step transformer.
Is it efficient and quiet?
Yes, aerodynamically optimised impellers and guide vanes give low specific fan power (SFP), high efficiency and a low sound level.
Is it suitable for outdoor or wet-room duct runs?
Yes, the airtight sheet-steel casing and IP55 terminal box make outdoor mounting and wet-room applications possible.
How is it installed?
The FK mounting clamp makes installation and removal easy and prevents vibration transfer to the duct. As a mains fan it should be installed by a qualified electrician.
