Title:
CIRCULAR SAW APPARATUS WITH INTEGRATED MULTISTAGE FILTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/168360
Kind Code:
A8
Abstract:
Various dust collection apparatuses are disclosed. In a first example, a dust collection apparatus includes a vacuum source configured to provide a negative pressure, and a multistage filter configured to collect airborne dust drawn by the negative pressure. For this example, the dust collection apparatus includes a dust tray having a shared dust containment area in which the shared dust containment area is a single compartment configured to receive the airborne dust collected by the multistage filter directly from each of a plurality of stages of the multistage filter. In another example, a dust collection apparatus includes a filter, a filter housing configured to house the filter, and an inlet coupled to the filter housing. For this example, the inlet is configured to receive a flow of airborne dust drawn by a negative pressure, and is further configured to mitigate an impact of the airborne dust on the filter.
