Systemair Prio 400 Circular Duct AC Motor - 400mm

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.
