What To Look For in a Dust Extractor
The best dust extractor should have a powerful motor that can generate plenty of suction power. Mains-powered dust extractors should come with at least a 1,000 Watt motor and produce at least 50 litres/second of suction power. Cordless dust extractors are more versatile but less powerful and typically generate 20-30 litres/second of suction power.
A filter that can extract the finest dust particles is obviously a very important dust extractor feature – one that can trap a 0.5 micron particle is the standard to aim for.
The length of the hose can make a big difference when you are working with a dust extractor. Hose lengths can vary from less than 2 metres on a cordless machine to 3.5 metres on some mains-powered extractors. Check that there is a flexible hose storage solution.
Dust collection bins can also vary a lot in size – from 10 litres on cordless models right up to 50 litres. Clear bins let you know exactly when to empty them.
Having a dust extractor that can deal with both wet and dry debris is obviously a big advantage. Spills and wet dust can be cleaned up in seconds.
If you are going to use a dust extractor in conjunction with a power tool make sure the extractor has a power tool adaptor. More sophisticated dust extractors feature a power take-off function, where you can plug your power tool into the extractor, and it automatically turns it on when you’re cutting or sanding.
Don’t forget the accessories. These should include a selection of adaptors, tubes and nozzles, ideally stored “on-board”.
Fine dust particles aren’t just dirty, they can be harmful to your lungs as well. Combat the dust in your shop with the best dust extractor you can afford.
