ABSTRACT:
A blower/vacuum system includes a power unit with a rotatably mounted fan for inducing an air flow from an inlet to an outlet. In the vacuum configuration, a pick-up tube having a relatively wide inlet opening is connected to the inlet of the power unit to direct the debris into the fan housing. The fan includes widely spaced fan blades that are sufficiently wide to accept and pass the expected range of non-frangible debris, including pine cones, seed pods, gum balls, and the like. The debris is passed through the fan housing to the outlet and to a dual-porosity collection bag having front, top, bottom, and side portions fabricated from a fabric having a first air flow porosity and a rear portion fabricated from an another fabric having a second air flow porosity that is higher than the first air flow porosity so that the entire fabric surface will function to exhaust the air flow with the major portion of the air flow flowing through the rear portion to direct the exhaust air and any dust and other particles away from the user. In the blower configuration, a discharge tube is connected to the outlet to discharge the exhaust air through the end of the discharge tube.
