Systemair Prio AC - duct fans with AC motor
The Systemair Prio AC / Prio EC circular fans are designed to be installed directly into the ductwork. Systemair Prio AC / Prio EC fans have specially developed aerodynamically optimised impellers and an external rotor motor. The speed of the Systemair Prio AC fans can be infinitely controlled by a thyristor or a 5-speed transformer.The speed of the Systemair Prio EC fans can be easily adjusted using the built-in potentiometer or can be controlled using an external 0-10 V signal. SystemairPrio AC / Prio EC circular duct fans are equipped with motors with built-in thermal contacts with manual restart according to EN 60335-2-80.
The airtight casing of theSystemairPrio AC / Prio EC fans (airtightness class C according to EN 12237:2003) is made of a special composite material. The FK quick-release clamp allows easy installation and removal and dampens the transmission of vibrations into the ductwork. A mounting bracket is available as an accessory - not included. When installing in wet environments, we recommend installing a timer.
Airtight, compact casing made of composite material (150 to 250 mm diameter), Aluzinc (315 to 400 mm diameter) or galvanized steel sheet (450 to 500 mm diameter). Thanks to the newly developed idler plastic axial impeller with flow optimization, prio fans achieve best-in-class SFP values.
