With an RHGC chimney fan from Exodraft, optimal draft can be created in the chimney by means of negative pressure in the flue pipe and chimney. RHGC has a horizontal exhaust, which means that the smoke is sent out to the side and not vertically up.

RHGC features a built-in monitoring system, consisting of a pressure switch and a flow measurement system. Exodraft’s EFC21 control unit must be connected to the pressure switch to monitor the fail-safe function. The fail-safe function checks whether there is sufficient draft in the chimney; if there is not enough draft, the gas supply is shut off to prevent gas leaks.

The chimney fan is constructed to withstand continuous temperatures up to 200 °C. It is made from 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, a centrifugal wheel, a cooling plate, a mounting plate, hinges, screws, and bolts. The motor is temperature-resistant and enclosed, while the centrifugal wheel and cooling air openings ensure that the motor is continuously cooled as much as possible. The motor cable is also heat-resistant, strain-relieved, and protected by an external armored hose.

All of this ensures the chimney fan’s long lifespan and high operational reliability.
