The RSVG was developed specifically for gas fireplaces and individual gas-fired boilers.

The chimney fan has a vertical discharge and an integrated monitoring system, consisting of a pressure control switch and a flow control. The RSVG is installed on top of the chimney and provides a controlled vacuum regardless of location, size or height of the chimney. The chimney fan can be used for both new and existing installations.

The RSVG is part of an Exodraft system and must be connected to an Exodraft EFC21 control. See below for matching accessories.



The RSVG chimney fan is made of corrosion-resistant cast aluminium and designed for operation in hot and corrosive environments. The chimney fan withstands flue gas temperatures up to 200 °C and is delivered with a centrifugal impeller, which enables high efficiency.

The chimney fan has an enclosed heat-resistant asynchronous motor with permanently lubricated ball bearings that was developed especially for use in high temperatures.

The motor is placed so that it is protected from flue gases and a special cooling vane wheel as well as cooling air slots that safely ensure continuous cooling of the motor. 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.


Integrated Security

The built-in chimney fan pressure control switch is connected to the associated Exodraft control that monitors the fail-safe function. The fail-safe function monitors whether the chimney draught is sufficient. If this is not the case, the gas supply is shut off and a gas leak is prevented.

The chimney fan can be opened so that it is easily accessible for maintenance and repair work and a stainless safety mesh is mounted to protect fingers and birds.
