    • A power saw having a circular saw blade or, grinding wheel incorporated to a dust collection system that is easily portable is disclosed herein. In a preferred embodiment, negative pressure and resulting air flow is provided at a lower blade guard to capture particulate matter as a byproduct of cutting a work piece. A unique dust collection housing is additionally provided having a filter to remove dust from air and exhaust the filtered air at a lateral side of the saw. A spin handle is additionally disclosed to increase the usable surface of the filter and to work in conjunction with a filter cleaning flap. A drive belt according to a preferred embodiment, drives the circular saw and a vacuum fan. Among the beneficial aspects of the power saw is its portability by obviating a need for a dust collection bag and/or a separate vacuum unit.
    • 本文公开了具有圆锯片的电动锯或者与易于携带的集尘系统结合的砂轮。 在优选实施例中,在下刀片护罩处提供负压和所产生的空气流,以捕获作为切割工件的副产品的颗粒物质。 另外提供了一种独特的集尘壳体,其具有过滤器以从空气中除去灰尘并排出锯的侧面处的过滤空气。 另外公开了旋转手柄以增加过滤器的可用表面并与过滤器清洁翼片一起工作。 根据优选实施例的驱动带驱动圆锯和真空风扇。 功率锯的有益方面是其可移植性,因为不需要集尘袋和/或单独的真空单元。

    • Dust and debris resulting from the sawing or cutting of concrete masonry units, blocks, bricks, tiles and other masonry products is collected via a three point dust and debris collection system. A movable work supporting table for cooperation with a masonry saw has a grated surface, a vacuum chamber below the grated surface acting as one collection point or area, a heavy debris collection chamber below and in communication with the table vacuum chamber acting as another collection point or area, and a shroud or hood assembly extending rearwardly from the table adapted to extend about the sides and rear of the saw blade and including a vacuum chamber acting as a primary collection point or area. The system is highly effective in achieving dust capture.
    • 通过三点灰尘和碎片收集系统收集通过锯切或切割混凝土砌块单元,砖块,砖瓦和其他砖石产品产生的灰尘和碎屑。 用于与砌体锯合作的活动工作支撑台具有磨光表面,作为一个收集点或区域的磨碎表面下方的真空室,位于作为另一收集点的工作台真空室下方并与之连通的重屑堆集室 或区域,以及从桌子向后延伸的护罩或罩组件,其适于围绕锯片的侧面和后部延伸,并且包括用作主要收集点或区域的真空室。 该系统在实现除尘方面非常有效。
