The GAS 20 L SFC from Bosch is a wheel mounted 19 Litre Professional Wet/Dry extractor essential for any workshop. It can be attached to power tools directly to extract wood dust and chip as you make it, or can be used like a vacuum cleaner to clear up dust, dirt and other mess around the work area. It boasts an impressive 62 litre per second maximum air flow that allows vast amounts of dust and waste to be extracted quickly and efficiently. The GAS 20 L SFC isn't just a dust extractor though, it can also be used to clean up liquid mess too, making this unit an excellent all rounder.
