The RS chimney fan from Exodraft, ensures the optimal draft in the chimney by creating negative pressure in the flue pipe and chimney. The RS has a horizontal discharge, meaning that the smoke is directed sideways and not vertically upwards. The chimney fan is designed to withstand continuous temperatures up to 250 °C. It is made of cast aluminum, and all screws and bolts are stainless steel.

The chimney fan consists of a motor cable, a top section, a motor, an axial impeller, a cooling plate, a base plate, hinges, screws, and bolts. The motor is temperature-resistant and enclosed, while the axial impeller and cooling air openings ensure that the motor is continuously cooled as much as possible. The motor cable is also heat-resistant and strain-relieved, as well as protected by an external armored hose.

All of this ensures a long service life and high operational reliability for the chimney fan. If the chimney sweeper needs to clean the chimney, he can easily open the chimney fan and access it without any problems. Since the axial impeller is made of stainless steel, he can also easily clean it of soot and any deposits when he is already on the roof.

For safety reasons, a stainless steel mesh is installed in the discharge opening to protect against birds and contact.
