The Bosch GXA3-01L PRO+GUARD™ Drilling Kit features a HEPA filter, fleece filter bag and other accessories to upgrade the VAC090-series dust extractor. The VF130H HEPA Filter captures 99.97% of particles 0.3 microns and larger, and it has a low-stick surface to enhance the filter-cleaning process. It helps users move toward compliance with the OSHA respirable crystalline silica dust regulation. The VB090F Fleece Filter Bag acts as a preliminary filter, and the port cover securely closes to keep the dust inside during disposal. The filter and fleece bag are for use in dry applications only. The HDC200 dust-collection attachment for concrete drilling is optimized for drilling diameters from 5/8 In. to 1-3/8 In. It has two air chambers: one for drilling bit to pass through to extract dust, the other to maintain suction to the wall. The L-Boxx-3 tool carrying case (part of the L-Boxx tool-storage system) is also included. The case integrates with the dust extractor for a mobile workstation.
