Thread: 150mm to 100mm

You can but it won't work as well as a single 150 mm. It takes 3 x 100 mm ports to equal the flow of a 150mm duct AND two ports may fight each other for some of the same air/dust and contribute to turbulence.

Can seem to find adapter which you can connect a 150mm pipe into with 2x 100mm outlets - do they exist?

The way this is done is by using a 150 Y with a 100 side entrance
EG 5a on this pGE STORMWATER FITTINGS - STORMWATER JUNCTION - Pipe Online - Retic Fittings , Plumbing Fittings, Reticulation Supplies supplied Australia wide

and then adding a 150/100 level invert to one of the 150 ends
EG 4A ON THSI PAGE DWV FITTINGS - DWV LEVEL INVERT - Pipe Online - Retic Fittings , Plumbing Fittings, Reticulation Supplies supplied Australia wide

The photo shows one of these 150/100mm Y's (Y) and a Level Invert (L) that I use on my OH TS guard.

I see makes sense looks like sticking with 6" is better

Do you know where one can get those spring clamps for 6" flex hose? So you can take it off by squeezing to put it onto another machine?

You would be better off making something like this

Thanks Chris that's a great idea and something very easy to 3d print

That's what I did due to limitations inside my TS cabinet. Only I started with 5" instead of 6".
Instead of a BMH I just added a rectangular hood from H&F. Reason being, I wanted to catch the heavier dust that falls from the front of the blade shroud as well as some of the finer dust. I intend extending the sides of the hood to increase the capture area. A rectangle makes that much easier. It's not ideal, but it's better than what I had before.

If you're going for cross-ventilation to collect fine dust, then a BMH would be the go.

do you have a 3D printer, if so can we talk business

tried sending a PM Qwertyu but your box is overloaded ...

if you are thinking of making some of these magnetic units shown by Chris, I would be interested in more details... both 100 & 150mm sizes 3 sets of each at this stage
