Hi since I have two lovely as new squirrel fans from which I intend to make a large rectangular ceiling type boxed fine dust extractor.So can anyone show me any books designs on this type also interested in a floor mounted for later in the yeaar, but this type on the ceiling would be best for these fans.Any blogs articles books etc with designs on this type I would like to see and design my own.You’ve seen them a box rectangular or sometimes a drum design for the smaller ones fitted on chains from the ceiling and remove the very fine airborne dust.I have made one already with a few bathroom fans and it works but maybe I need to see a more professional design on this .Or indeed as said for a leter in the year project the floorstanding type as I have an impeller type metal fan for this with a 110 volt motor thanks any help would result in a big fat (cheque) no sorry delete that what I mean is thanks

-- excuse my typing as I have a form of parkinsons disease

not plans, but here are a couple of such cleaners I’ve seen on lumberjocks that I really liked, you could try and plan a similar case:

Just be sure the fan “pulls” the air through the filter, rather than “pushing” it through. Some discussion of various filter / fan systems is on Sawmill Creek.

Here’s the one I made with a large squirrel cage blower:

Hope it helps.

An important point is the position of your dust extractor. Usually it is located along a wall in order to create an air flow pattern that will pick up dust. The outlet of the DE should be as far away from the inlet as possible. A short piece of duct at the outlet will carry cleaned air away and direct it into the air flow pattern. I hope I’ve expressed myself clearly.

Have your say...
