I'm looking at sorting out a decent extraction system for my small workshop.
Due to lack of space and cost of parts, I'm planning on buying one of these (http://www.mtmc.co.uk/product.asp?P_...=any&PT_ID=all) . The plan is to remove the motor unit and use it with some form of separator (hopefully a cyclone).
So, I've looked into the cost of 6" ducting, and it's horrific. However, 4" plastic ducting (drain pipe!) is very cheap. I was wondering if you could pair up 4" pipes (i.e. oo instead of o) as that would be close to the cross-sectional area of a 6" pipe.
As most of my tools have 4", 2 1/2" or approx 1 1/2" ports, I'd have to make/buy adaptors regardless of the size of the main and channel runs. The only concern I have is possible turbulence issues in the joins between single and dual pipe runs.
Anyone knowledgeable in this area?
Also, does anyone know of good sound deadening solutions - my workshop is in a residential area, and the distributor tells me they think this motor is over 90dB!
Thanks.
