With an RSHG chimney fan from Exodraft, optimal draught can be created in the chimney using negative pressure in the flue pipe and chimney. The RSHG has a horizontal discharge, meaning that the smoke is expelled sideways and not vertically upwards.

The RSHG has a built-in monitoring system consisting of a pressure switch and a flow measurement system. The Exodraft control unit EFC21 must be connected to the pressure switch, which monitors the fail-safe function. The fail-safe function checks if there is sufficient draught in the chimney, and if there isn’t enough draught, the gas supply is shut off to prevent gas leakage.

The chimney fan is designed to withstand up to 200°C continuously. It is made of corrosion-resistant aluminum, and all screws and bolts are made of stainless steel.

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

All these features ensure the chimney fan has a long service life and high operational reliability.

When 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 up on the roof.

For safety reasons, a stainless steel mesh is mounted in the discharge opening as bird and touch protection.
