The RSHT has a horizontal discharge and is made of stainless steel with an aluminium housing. The chimney fan is equipped with a stainless steel axial impeller. The same is true for all screws and bolts.
The patented cooling wheel allows continuous operation of the chimney fan at temperatures up to 500°C. Peak loads (up to 3 minutes) with temperatures up to 700°C are possible with the RSHT. The engine is a heat-resistant asynchronous motor in an enclosed construction with sealed, maintenance-free ball bearings that is continuously adjustable with a TRIAC control.
The cable is heat resistant and strain relieved and protected by a reinforced hose casing. All of these combined give the chimney fan high operational reliability and a long service life. The chimney fan is hinged, which means the chimney sweeper has easy access to sweep the chimney. A protective stainless steel grille is mounted to prevent contact and stop birds from entering the chimney.
