Thank you for sharing your knowledge on dust collectors and filtration systems.

If you are above minimum you get maximum collection efficiency. Shop vacs come in a variety of CFM but the saw manuals give a minimum CFMĬoncrete grinding orlando. They have built in dust ports and just take any shop vac. Not working with the fine dust was a deal breaker for me. I had zero success with it when trying to catch fine drywall/sanding dust- but it worked great with planer shavings. The only Festool disappointment I have had has been with their dust cyclone system. It won't suck up big debris like a typical 'Shop Vac'. It isn't unusual for the bag to look like the cavity it is in when it is full of concrete grinding boston. Never have had a problem with bag clogs or dust not completely filling up the bag.

Festool/Tanos Systainers will attach to the vacuum for transport. Some of their bigger models have a feature that will automatically shake the dust bag to maintain suction- but a special bag may be required. Especially with concrete and drywall dust that plugs filters quickly.įestool is probably hard to beat. 3M is famous for selling overpriced filters that reduce system performance. If you are above minimum you get maximum collection efficiency.īuying super high filtration filters kills air to cloth ratio over OEM filters. Shop vacs come in a variety of CFM but the saw manuals give a minimum CFM. Using a Festool dust extractor on a Dewalt grinder is not a good idea. So the best dust collector is the one built specifically for a specific tool. Just saying so you get what the technology limits are. If it’s too much it won’t capture the dust and you are forced to use a bigger blower which means a bigger filter. If air flow is too low or high it doesn’t work: Also you need a certain CFM based on the opening it is sucking air through, the gaps around the tool. The thing is there is a balance called the air to cloth ratio which needs to be under about 4 and the pressure drop needs to be between 2 and 8 inches: for ANY filter. The filters and blower are basic tech until you get into large systems where you get pulse jets and Torit systems.
