a user interface engageable by a user to input one or more working parameters,
a duct holder couplable to the blower, the duct holder including a flexible duct configured to extend from and direct an airflow generated by the blower;
and
an electronic control unit coupled to the blower and configured to:
distribute power from a power source,
receive one or more signals indicating one or more operating conditions of the blower system, the operating conditions including a battery energy signal, the airspeed signal, and an air quality signal,
receive one or more signals indicating the working parameters from the user interface, the working parameters including a runtime, a fan speed, a confined space volume, and a number of air changes, and a minimum flow rate,
determine a total maximum power of the blower system based on one of more of the operating conditions and one or more of the working parameters, and
output one or more blower control signals to control operation of the blower based on the total maximum power of the blower system.
