An assembly for preventing and treating moisture-based skin dermatitis includes an air flow conditioning module positioned in the output air flow in the output air flow chamber for increasing or decreasing the temperature of the generated air flow as received from the fan responsive to a received control signal, a temperature sensor positioned in the output air flow at the nozzle for sensing a current temperature of the output air flow as conditioned by the air flow conditioning module, an air flow conditioning control module is coupled to the air flow conditioning module and the temperature sensor and is configured for generating the control signal, and air flow conditioning control module that has a defined maximum temperature of the output airflow and is adapted for receiving the sensed current temperature from the temperature sensor, comparing the current temperature to the defined maximum temperature, and generating the control signal to provide the generated air flow at the nozzle does not exceed the defined maximum temperature.
