Abstract: Roof drying processes and associated systems. A representative process includes drawing moisture-laden air from within the internal structure of a roof via a vacuum blower, a extraction insert and an extraction manifold, and removing moisture from the moisture-laden air via a dehumidifier. The dry air can be directed back into the roof through an injection insert and an injection manifold.

Abstract: Contoured fan blades and associated systems and methods are disclosed herein. A representative embodiment includes a hub and multiple curved fan blades circumferentially arranged around, and coupled to, the hub. Individual fan blades can have a tip, a first curved edge, and a second curved edge. The first and second curved edges extend over at least part of the length between the hub to the tip of the fan blade. The fan blade is formed with multiple upper channels and multiple lower channels. The multiple upper and lower channels extend from the first curved edge to the second curved edge.

Abstract: Methods and systems for controlling pressure washer devices are provided. Pressure washers comprising at least one control unit and the ability to regulate functions of at least an engine of a pressure washer are disclosed. A control unit receives inputs from a user or various sensors provided in communication with the control unit, and is further capable of outputting a signal based on the inputs, the output signal operative to maintain or control the operating functions of an engine, pump, or motor.
