Using a Ducted DC as a vacuum cleaner
Hello all (once again),
I now have a 4hp ducted DC setup with a cyclone. I am comfortable (although still have some bell-mouth work to do) that I am capturing the vast majority of fine dust, however.....
even with such a big beasty the bigger stuff (so far, especially the lathe but am expecting the same when I give the bandsaw a proper workout) I am still getting plenty dropped on the floor (and cabinets, etc). At the moment I am sweeping this up but think I should be able to attach some smaller flexi (after doing the reducing from 150mm) and make use of my 'beast'.
In doing research, I found: Vacuum cleaners work on the principal of a low volume of air traveling at high velocity, while extractors work on high volume air, traveling at low velocity. I also thought I had seen (on this forum) reasons to keep the two separate but can't find anything this time around. When I did a bodgy job of connecting my leftover 150mm flexi it seemed to pickup most of the crap on the floor.
I am thinking of plumbing the vacuum through an old pram so I can wheel it around but also be able to remove it to get into hard to get places.
Another option is a floor sweep connected to the DC but for hard to get places and bench tops this does not seem as good
Surely I can't be the first to consider this and others have tried it out one way or another.
cheers
Mick

their are some video's on YouTube that have a floor sweeps incorporated into the cyclone system, myself In putting a fixed point in the corner of the shed were I can sweep the floor waste in too. the second point pick up is using a old vacuum unit incorporated into the small cyclone unit, for cleaning down bench's.

I know a few folks that do this. I often unhook one of the 4" flexies on my BS to tidy up after cutting, same with the 4" flex on the overhead guard of the table saw.

The flow rate with 2" is lower than a vacuum cleaner but it still works albeit with a smaller radius of collection.

It was always a sure thing that BobL would have tested this out. Originally Posted by mick59wests

However, when I have larger chips, long strips of scraped-off PU glue or anything else the vac might struggle with or which might clog the vac I use the 4" flexy. I have a courtyard outside my shop, and the 4" flexy works a treat to pick up all the leaves that blow in.
Have fun!
