Bosch Professional All-Purpose Extractor - GAS 12-40 MA Professional - Blue

M-Class certification indicates that the extractor can capture 99.9% of airborne dust particles with an assigned limit value (ALV) greater than or equal to 0.1 mg/m³. This ensures a high level of protection against harmful dusts like silica.

The frequency of filter cleaning depends on the type and amount of dust being extracted. The Automatic Filter Cleaning (AFC) system helps maintain performance, but the filter should be inspected regularly and cleaned or replaced when visibly clogged or if suction power significantly decreases despite AFC operation.

While designed for professional use, it's recommended to use it with tools that generate dust. For optimal dust extraction, connect directly to compatible Bosch Professional power tools using the provided adapters, or use the general-purpose suction hose.

The hose-less design allows you to remove and empty the dust container directly without detaching the suction hose, making the process quicker, cleaner, and more convenient.

The AFC system periodically blows air back through the filter to dislodge accumulated dust, preventing clogging and maintaining strong, consistent suction power throughout the operation.

Yes, the GAS 12-40 MA Professional is specifically designed to handle fine dust, including that generated from plasterboard sawing and drywall sanding, thanks to its M-Class filtration and AFC system.

The extractor is L-Boxx compatible, meaning you can securely stack and transport your L-Boxx containers with it. Integrated storage is provided for the hose and accessories.

Check if the dust container is full and empty it. Inspect the main filter for heavy clogging and clean or replace it. Ensure the AFC system is functioning correctly.

Ensure the filter is correctly installed and not damaged. Clean the filter thoroughly. Check the user manual for specific AFC activation procedures.

Verify that the power cord is securely plugged into a working outlet. Check the power switch on the unit.

Ensure the unit has not exceeded its maximum fill line. Check that the filter is suitable for wet use or has been removed/cleaned as per instructions for wet operation.

Check for any blockages in the hose or nozzle. Ensure the dust container is properly sealed. Inspect the motor housing for any loose parts (refer to manual for safety).
