Workshop dust extraction...help!

[ptjw7uk]

Problem with fine dust extraction is the clogging of the filters.
Most woodwork shops do it using 2 filter extraction systems a high rate coarse filter as in the one you pictured and a fine dust air borne dust system.
The fine dust one you can usually make yourself, just a fan, a box and some fine filters.

You can buy the parts from Axminster( foot of page)
It will ultimately depend on how much dust you make.
I use a Dewalt extractor which removes most of the dust but it needs to be cleared of the fine dust else it slows up. They used to make a fine weave bag but that needed a holder to hold the bag up and that really clogged easliy(I cannot find them on the web so I dont think they are made now)
Anyway if you are doing lots then the one you showed is better , the 100mm will allow lots of air flow and should also extract the larger chips, well mine does. I also use mine on the planer and that really makes chips!!
