About Bosch GAS 400 A L Class All Purpose Dust Extractor

The Bosch GAS 400 A is an L Class all purpose dust extractor. It handles wet and dry material. It copes with fine dust and heavy debris. It is aimed at carpenters, builders and other trades.

The star feature is Automatic Filter Cleaning. It keeps the filter clear while you work. Suction stays strong and steady. That means fewer stops to clear blockages. It suits sanding, grinding and general site clearance.

Emptying is simple. The container has no hose attached. The motor head stands alone and will not tip. You can split them without unplugging a hose first. Integral hose storage keeps the unit tidy and easier to move.

The unit is 580mm long and 389mm wide. It stands 536mm high. It weighs 14kg. The box holds a hose, a floor nozzle and a combi brush nozzle. You also get three extension pipes and two disposal bags. That is a handy starter set for most jobs.

The Technology Explained

Dust extractors lose suction as the filter clogs. Automatic Filter Cleaning tackles that. It clears the filter while you keep working. Suction stays level and you stop less. The L Class rating covers low risk dust such as common wood dust. The motor head is separate from the container.

Using It Safely

Isolate the unit from power before changing filters or opening the container. Keep the hose away from blades. Do not tip the unit while it runs. Empty the container before it is full. Check the filter is fitted. Wear a mask when emptying fine dust.
