Record Power DX4000 Vacuum

Hello, looking at the DX4000.
My thoughts on this.

• The DX4000 is a twin motor 2 x 1000w Vacuum that filters down to 0.5microns.
• With both motors switched on it produces 224cfm or 6360 litres per minute almost twice the flow of a Festool.
• As it is a High pressure / Low Volume vacuum I am considering using it as:
  
  • One motor running, connected to a dust cyclone and reducing the diameter down to 32mm from 100mm and using it on hand tools - sander?
  • With both motors running connecting to jointer, thicknessser, table saw through the 100mm connection?

Anyone have a DX4000 that they can share some thoughts / views?
Any thoughts on how I am thinking of using it?
Thanks....

Firstly welcome to the forums.

Most manufacturers overstate the flow rates generated by Vacuum cleaners and dust collectors.
The reasons for this are
1) they use a flow determination method which is flawed.
2) The method assumes clean filters and no hoses or attachments,
I have measured the flow rates of a number of Vacs and duct extractors using a more accurate procedure and not many have come close to their stated flow rates.
A safer assessment of the real flow generated by vacs and DCs is about half the flow claimed by the manufacturer.

To control fine dust emission from machines like jointers, thicknesssers, table saws you will also need about 3-4x more flow rate at the source of the dust than that claimed above.
Remember it's the fine invisible dust that represents the greatest risk, the sawdust that you can see will not normally lead to problems.
This can only be done using a low pressure high volume dust extractors and 150mm ducting and by opening y the dust ports on machines to make use of the 150mmducting as it is rather pointless to run 150mm and connect that to a 100mm dust ports.

What I suggest you do is read as much as you can about wood dust on this forum and see how woodworkers are handling this problem and then get back with specific questions..

A vac is best suited to be used on power tools but like any dust collector it's best if it is located or vented outside, No matter what is done they always leak fine dust and as it cannot be seen it represents a health risk.
