    RSG

    RSG_fritlagt

    An exodraft chimney fan RSG provide a controllable negative pressure along the full length of the flue and chimney.

    A fail-safe system is fitted in the fan which automatically measures the velocity of the flue gases. Only when the velocity exceeds the preset and safe level can the gas appliance be used. The fail-safe system prevents any spillage from the gas appliance as well as any leaks of CO and other poisonous gases.

    Fan type RSG is installed on the external wall and thereby enables a gas appliance to be installed in a room with no chimney. The power of the fan will allow for long horizontal flues up to 15 meters.

    A silencer type SLR is available as an accessory for the
    fan type RSG.

    Construction

    The fans are specially made to work in a hot and dirty environment and can withstand temperatures up to 180 °C at the flue exit.

    The fans are made from galvanised sheet metal, fitted with a centrifugal impeller that is very resistant to dirt in the flue gases.

    The fans are fitted with an entirely closed, asynchronous motor with ball bearings sealed for life. The motor is specifically constructed to provide reliable operation at a high temperature. It is made to international classifications IP54 (protection class) and F (insulation). The motor is located inside the motor housing and thus separated from the flue gases.

    The electrical connection is provided by a heat resistant silicone cable withstanding 200 °C.

    The built-in pressure switch in the chimney fan is wired to the appropriate exodraft control unit which supervises the fail-safe function. Only when the draught exceeds the preset and safe level can the gas appliance be used. The fail-safe system will prevent any spillage of combustion products from the appliance when the fan and the controller are commissioned correctly. In case of insufficient chimney draught, the heating appliance will be shut down.

    Lw = Sound effect level dB. (reference: 1 pW)
    Lp = Sound Pressure level dB (A) at a distance of 10 m from the fan at halfspheric sound distribution.
    Lp (2 metres) = Lp (1 metre) – 6 dB.

    Chimney fan selection RSG

    Please use the exodraft fan selection chart or complete
    an appraisal form.
    exodraft offers a free fan selection service
    – the correct chimney fan and control unit are calculated according to EN 133845

    The capacity chart is measured at a flue gas temperature
    of 20 °C. The fan capacity changes with temperature.
    Correction of system pressure loss for flue gas temperature higher than 20 °C is calculated:6

    ExampleSystem need: 500 m3/h and 90 Pa at 180 °C

    Selection of fan: 500 m3/h and 139 Pa at 20 °C
