AR Sileo 4 Pole 250mm Cased Axial fan for Single Phase supply.
Max Duty - 982m3/hr
Max Power Absorbed -50W
AR Sileo 4 Pole Cased Axial fans for Single Phase supply, the AR Sileo range do have a bionic shape of the fan blade, and are driven by external rotor motors. The AR range is mounted in a round casing according Eurovent 1/2 made from galvanized steel, and is completely painted in black (RAL9005).

• speed controllable by voltage reduction
• inlet protection guard
• safe and maintenance free operation
• can be installed in any mounting position
• electric connection via terminal box mounted on the casing
• supplied with capacitor

The axial impeller is manufactured from pressure die cast aluminum and is painted in black. The impeller is balanced dynamically in two levels in accordance with DIN ISO 1940 part 1, quality G6.3.

The motors are equipped with thermal contacts for motor protection, with leads to be connected to a motor protection unit, for example Systemair unit S-ET.
