Help needed on dust extraction

[RPM10000]

Hello All,

I have just got hold of a Jet 310 P/T and I now need to do something for dust extraction. We all know about the dangers that wood dust poses so I was thing about following the same rough idea of Barry Burgess' set up that being a cyclone and 0.5 micron filters on a chip extractor. I have found Lyndhurst FM300S 3HP extractor (at a good price :wink: ) which I will be using as the base of my set up.

I had though about following something similar to this guys setup

What you don't see in the picture is that it's wall mounted and the cyclone drops into a steel drum under it.

Partly thinking of something like this as I have a pretty small workshop and a dual bag extractor will take up a lot of room once you add in the cyclone.

To the bits that I need some advice on.

What issues will I get if I take my two bag system and make it into a single bag?
What sort of drop in airflow might I expect to see given that I would expect something like 3000 m3/hr at the moment?
Will 3HP be too much airflow for a single filter?

Thanks for any help you can provide.

You need to have sufficient filter area to handle the actual air intake
When you say 3000M3/hr what size duct is that based upon. The problem is that if you use a smaller diameter say only say 100mm you will not achieve anything like the airflow. In simple maths terms if the design duct diameter was 150mm and you only use 100mm you will have immediately restricted yourself to around half the airflow
