The Bosch GDE28D is a remarkable mobile dust extractor. It's designed for users of the Bosch GBH18V-28DC 18V Bulldog™, enabling them to have top - notch mobility on the jobsite with just one battery. This dust - extraction solution is a game - changer. It comes with a filter cleaning mechanism that easily gets rid of excess dust and debris from the filter. The HEPA filter is a key feature, helping users meet OSHA silica dust regulations. The extractor attaches to the hammer, using the hammer’s fan to create suction. Once you engage the hammer trigger, the collector activates. It has auto power - on for instant vacuum suction when drilling and auto power - off with a 2 - second delay after releasing the trigger to collect remaining dust. Included are two Dust - Eye options (a small and a large one) and a 4 - inch extension. The large Dust - Eye can handle bit diameters up to 1 - 1/8 inches, and the extension can accommodate bit lengths up to 10 inches. The aluminum guide rail ensures smooth retraction of the Dust Eye during drilling. The transparent dust container makes it easy to check the dust level, and there's a 'Dust Box Empty Flap' at the back for quick dust removal. This product also comes with a dust container, a HEPA filter, a 5/8 - inch Dust Eye, a 1 - 1/8 - inch Dust Eye, and a 4 - inch extension.















Using the Bosch GDE28D is a breeze. First, attach it to your Bosch GBH18V - 28DC 18V Bulldog™ hammer. Once it's attached, you're ready to go. When you pull the hammer trigger, the dust collector will automatically turn on and start sucking up the dust. After you're done drilling and release the trigger, it'll keep running for 2 seconds to collect any remaining dust. Check the dust level through the transparent container. When it's full, simply open the 'Dust Box Empty Flap' at the back to remove the dust. For the filter, turn the nob to clean off excess dust and debris from time to time. This will help you keep using the HEPA filter effectively and stay compliant with OSHA regulations. Remember, this is for dry applications only. Don't expose it to water as it might damage the unit. Keep it in a dry place when not in use to ensure its long - term performance.
