Systemair AR

Systemair AR ducted axial fans are designed for supply or extract air in low pressure systems in various commercial or industrial buildings. Systemair AR circular duct axial fans feature a noise-optimized Sileo axial impeller and a high-efficiency external rotor motor. Systemair AR duct fans provide high performance with minimal power consumption and maximum efficiency.

Benefits of Systemair AR circular duct fans:

• Sileo noise-optimised impellers.
• Installation in any position
• adjustable speed
• protective grille on the inlet
• maintenance-free

Design

The Systemair AR circular duct fan shroud is made of galvanised steel sheet with a RAL9005 black powder coated finish. A protective grille is fitted on the inlet of the ducted fan. Systemair AR circular fans have axial impellers that are made of steel, aluminium or composite material, are dynamically balanced and paired with matching motors. The terminal block is IP44 as standard and is located on the fan shroud.

Installation

Systemair AR circular fans with flange can be installed in any position. To prevent vibration transmission to the HVAC ductwork, we recommend using flexible sleeves for the connection.

Thermal protection and speed control

The motors are equipped with integrated TK thermal contacts, which must be connected to the corresponding thermal protection relay. Depending on the motor type, the fan speed can be controlled by a frequency converter with sine filter, thyristor, star/delta switch or 5-stage transformers.
