Thread: Draft Layout for 150mm ducting

A wide radius of curvature 90º bend (DWV) is better than 2x45º bends

1.) At the mitre saw I have only one Y junction, would I benefit from 2 Y junctions and running 2x 150mm flexible hose to both sides of the mitre saw

You would have to try it. The hard 150mm PVC ducting that the flexies are connected to can carry no more than ~120 CFM - that means you will have a max of 600 through each flex which means the air speed will also be a lot lower so won't capture scattering chips as well. Most MS hoods I have seen only use one 150 mm connect.

Ideally they should be as far apart as possible but I would not let that stop you putting them right next to each other. Sometimes there is no other way.Ideally they should be as far apart as possible but I would not let that stop you putting them right next to each other. Sometimes there is no other way..
2.) What is the minimum distance that I can have Y junctions near each other (on opposing sides), my table saw and thicknesser are about 1.2 metres from each other.

Thanks Bob, the DWS has the longer sweep.

1). Is it ok to get the other parts such as the y junction in Stormwater?
2). The inlet for my dust Extractor is located near the ground, is it ok to run a single DWS 90 degree angle upwards to the truss?

Thanks in advance.

(Edit, question answered in previous post)

Yes to both questions.

this may be a very dumb reply but from your drawing your Y pieces are facing away from the air/dust flow, I presume this is just the way you drew it. But I learnt the painful way of inadvertently placing one Y facing the wrong way and having trouble removing dust from it.

Please please when assembling keep in mind for a later stage auto blast gates they are the ducks balls. You never have to think about opening/closing again.

It is my drawing, but thank you, I will correct it on the final drawing.

The way I saw it half were correct and half were incorrect.
