Need some help with dust collection fittings for thien cyclone

[jc]

Hello, I tried searching but didn't find a definitive answer. 

I'm wondering if the vac end of the festool hoses (I believe they are all of the same diameter, for example this one: http://www.festoolusa.com/products/dust-extractors/antistatic-hoses/antistatic-hose-36mm-x-5m-452884.html) will fit into a 2.5" fitting such as this one here: http://www.woodcraft.com/product/2000899/9634/212-router-fence-dust-extraction-fitting.aspx

I'm toying with the idea of making a thien separator and am sourcing for the hose fittings.  Any suggestions for other ways to connect up the festool hoses to custom, preferably 2.5" dust collection fittings are also appreciated.

the best way is to go to your local pluming place and look . i have bought the same fittings in different places and some fit some dont.

i presume you are looking for the fittings  for a top inlet design. i would go with a side inlet  top hat design . i find it more efficient having no second pipe down in the way of the revolving air and dust.

my local hardaware shop sells down pipe joiners that fit the festool hose ends if you cut one part  off.

Hi Alan, I read some posts you made on your separator build.    Where did you get your 68mm downpipe fittings?  How's your thein separator performing so far?

I wanted to keep it simple so was intending to go with the top inlet design.  Although, I am planning some modifications... not sure if those modifications would aid or hinder it but I am familiar with some CFD software from my old work so I was also planning on running an airflow simulation to compare results.

Yes that fitting will work and the Festool end will fit. I used the same fitting only from LV

i get my downpipe fittings from my local agricultural /hardware shop .
i dont know the brand  but it is probably wavin or polipipe.

the small shop vac one is ok. i didnt follow the plans as i want ed to use the barrel i had. i will rebuild but use a top hat design.
my 4" build is working great. the slot is too wide thow ,so i do get some fine in the dc. i built it as a top inlet but changed it over to a side inlet when i noticed that the air traveling around the inside of the top hat hit the back of the inlet and reagitated the dust .

i am building a 6"version for my shop plumbed in system. thats not build yet .

Thanks for that useful feedback.

What size is your slot?

 

[Alan m]

not sure of the slot width exactly. i started with the 1,1/8" slot then (because of the air hitting the inlet issues) i widened the slot a few times.
it is probably about 1,3/4" maybe more. i wish i had changed the inlet first.

Yes, its the same fitting.

Awesome.  Thanks!

This is great - if I got it right..

Will the vac-end (the end of the Festool hose that goes into the CTL vacuum) fit in part A in the LV link above? I recently e-mailed LV and asked if the 2" parts would fit. They sait it would have to be duct taped. But it seems it is it the 2,5" parts I should use?

My understanding from this thread is that it would fit!  I haven't bought it from LV yet so that's all I can comment.  If you do get it, please post what you find out.  [smile]
