  • the present invention refers to a climate conditioning system having an electric motor associated with a fan.
  • the fan generates an air flow passing through a heat-exchanger element in a co-linear distribution, on the same axis to which modules in the form of filters can be added for handling of particles or bacteria, dust filters, as well as in the form of elements for controlling moisture, among others.
  • Equipment according to the background art necessarily requires an installation specialist after being acquired, in order to be able to operate them, because they are not functional without the proper adjustment and manufacture, nor without special fastenings and adapters to additional elements, such as ducts and fittings.
