This range of inline duct fans is powered by the latest technology in high efficiency backward curved motorised impellers, with profiled blades for high airflow, low noise and low running costs with the possibility to mount a bracket.

These are amongst the quietest fan units while maintaining high airflows (230 to 1725m³/h free air). All inlet and discharge spigots diameters are standard. They also feature air guide vanes in the casing to straighten the air to reduce noise turbulences.

The rotor comes painted to resist corrosion and the integrated connection box comes with IP44 ingress protection and in addition is a Class F insulated motor. The motor protection is integrated and is signaled via a digital output or a tachometer output. Our ‘RS’ range are powered by external rotor motor based fans which are 100% speed controllable.
