ABSTRACT:
The systems for reducing dust emissions include a dust catch. In some cases, the dust catch includes an inlet and a discharger. The inlet can be arranged so that it surrounds an abrasive surface of an abrasion device, such as a sander. Dust generated by the abrasion surface can be captured in the inlet and discharged by the discharger. In various cases, the inlet is associated with a skirt including a dust screen. The methods can include attaching a dust catch to an abrasion device such that an inlet of the dust catch encompasses at least a portion of an outer perimeter of an abrasion surface associated with an abrasion device. The abrasion device can then be operated and at least a portion of dust generated by operating the abrasion device is captured by the dust catch.
