The Bosch GAS 12-40 MA is a professional M Class wet and dry dust extractor. It is built for long jobs on site. The Automatic Filter Cleaning system keeps suction steady. A clogged filter will not stop you mid job. It suits concrete cutting, grinding, plasterboard sawing and dry wall sanding.
The filtration captures 99.9% of particles. That meets the protection level asked for under COSHH when working with hazardous fine dust. A 1200 W motor gives 71.5 l/s of airflow and 230 mbar of vacuum. The container holds 40 litres. Net capacity is 28 litres for dry and 20 litres for water.
Emptying is easy. The container is hose-less. The motor head stands alone and will not tip. You lift the head off and tip the container without taking the unit apart. A telescopic handle and four wheels help you move it. It is also compatible with the L-Boxx system. Integral hose storage keeps it compact.
Who needs it? Trades who cut and grind a lot and want a rated M Class machine. It weighs 14.1 kg. The box includes the main filter and hose. You also get a combi brush nozzle and curved tube. A fleece bag is supplied.
