All-purpose vacuum GAS 400 A. When fine or coarse dust is generated during work, a vacuum cleaner is needed that ensures good visibility by keeping the work area dust-free, without a clogged filter slowing down the job. Our GAS 400 A Professional saves time by keeping the filter free from clogs thanks to Bosch's proprietary, exclusive automatic filter cleaning technology (AFC). Its strong, constant airflow allows for faster completion of tasks. Dust disposal is also easier and quicker with the Bosch GAS 400 A Professional, thanks to the hose-free container and the independent, tip-resistant head. The Bosch GAS 400 A Professional extracts most materials, including wet or dry and fine or coarse dust. Its sustained strong suction power ensures highly efficient dust extraction, allowing work to be completed more quickly. 1 x main filter. 1 x hose. 1 x combination PT adapter. 1 x combination brush nozzle. 1 x curved suction pipe. 2 x disposal bags.
