Fan - Mezaxial

Product detailed description

Mezaxial fan S0111 for older ATMOS boilers

Code S0111 designates a Mezaxial type fan intended for older-version ATMOS boilers. It is supplied without a capacitor, which therefore has to be sourced separately.

This part belongs to the ATMOS spare parts group. Before ordering, check that your boiler corresponds to the older version for which this fan is intended.

Frequently asked questions

• How can I verify that the "Fan - Mezaxial" fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation from the rating plate of your appliance (boiler, storage tank, water heater) with the compatibility stated directly in the name of this product (brand Atmos) and in its technical parameters above. If in doubt, write to us with the exact type designation of your appliance (including the serial number, if applicable) and we will gladly verify the compatibility for you.
• Why is it important to use the original/compatible part rather than a universal replacement? Parts such as gaskets, sensors or safety components (safety valves, thermal fuses) are generally dimensioned precisely for the parameters of the particular appliance (pressure, temperature, electrical resistance of the sensor) - an incorrect part can cause reduced functionality, leaks, or, in the case of safety components, a real safety hazard.
• Does this part have to be installed by a professional? For simpler, mechanical parts (e.g. gaskets, covers, small accessories with no connection to electricity, gas or the pressure side), a skilled DIY person can usually handle the replacement after disconnecting the appliance from the power supply and the piping. However, for any work on the gas, electrical or pressure part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electrical modules), we always recommend a service technician - especially if the work could affect the warranty of the entire appliance.
• How do I know that this part is worn and needs to be replaced? Common signs are visible wear/cracking (for gaskets and rubber parts), a water or flue gas leak at the location of the part, an error message on the controller display (for sensors and electronic modules), or clearly reduced functionality of the appliance (e.g. irregular combustion with burner parts). If in doubt, the safest option is to have its condition assessed by a service technician during the regular annual inspection.
• Is it worth keeping this part at home as a spare? For parts that are normally subject to wear (gaskets, fuses, small mechanical parts) and whose failure would mean a heating or hot water outage, stocking up is a sensible precaution - especially for an older appliance, for which it may be harder to obtain the part at short notice.
