Hi i made a post a couple of weeks ago regarding making a diy ETM. The only thing I'm stuck on is the waste tank. I'm still not convinced that a metal drum will take the power of four 3 stage vacs in series/parallel. So I'm hoping some of you guys can give me any ideas as to where I could maybe buy a waste tank or get one fabricated that won't implode. I was thinking it would have to be made of steel but maybe something lighter or cheaper could be used like fibreglass or polypropylene. Any ideas would be greatly appreciated.

Thank you

Gary

what about scorpion tanks?

[gaz1984mcc]

i saw those on the WOC website only trouble is i need there to be 2 holes for where the vacuums go in and i think there only 1 already fitted to these tanks.

Look around for a second hand truckmount waste tank.

[gaz1984mcc]

I'm keeping a lookout Paul trouble is it's not the sort of thing you see for sale on there own very often thanks mate.

Gary i will ask on truckmouNters forum for you.

no, there are two holes
the top tank on the photo is the waste tank, as u can see on the left side is one hole connects with the machine and one on the middle that connetcs with the wand

Thanks Radek sorry i meant i needed 3 holes. one for the wand hose and 2 holes for each stack from the vacuums. I'm not to sure if it will affect performance if I use a Y connector for the vacuums rather than having 2 separate stacks into the waste tanks from the vacuums. Because i wanted the 2 sets of 2, 3 stage vacuums in series then both sets going to the tanks in parallel.

Thanks

Y splitter wont really  matter , In series / Parallel you wont have more CFM than the Scorpion , but you will have double the lift , which wont be as affected by the single port .

What vacuum motors are u going to use ...

[gaz1984mcc]

Hi John I'm just going to use some 3 stage lamb 5.7s for now maybe even 2 stage 5.7s after seeing how well the goliath etm/portable performs. So do you think using just a y connector on the end of both sets of vacuums going into the waste tank. Will perform the same as if i had 2 separate stacks into the waste.

Thanks

Just be carefull it doesn't end up like this. A guy tried to use it with his Prowler.

[gaz1984mcc]

OMG! WTF 

There was me thinking finally sorted. Maybe i need something a little stronger.

Thanks for the share John

 It wont really matter ,

Any four vacs will perform well  , but as u know Goliath is using two stage vacs primarily because its difficult to run two vacs on the one cord in the USA @ 120v  as they draw twice the amps per vac that we do at 230v .
So you could use two three stages on each cord no problem .  

If you are going to pay £100+ for each lamb three stage  , you might consider directly importing Motors  from Electro in the USA , might be around the same cost or less .

The conical electros would be 600+ airwatts where as the Lamb three stage is 450 ,  electro also have a conical two stage ( like a 5.7 version of the 6.6 ) which draws less amps than the three stage lamb but is also 600 airwatts .

Thanks John do you know which model of the electro's would be best suited for use in the UK?

I would say four of the conical two stages would make a nice machine without much chance of tripping breakers .
That would be the 230v version of this ...

The mytee escape is using four of the three stage version ...  so according to woodbridge its working OK here ...

The reference numbers above are pretty meaningless as they are just used by that distributor .
I'v read that Electro sell direct but not sure .

love that set up,how much did it cost??

[gaz1984mcc]

Thanks John I think I may go with the electro motors instead its a shame you can't get them in the UK though.

Thanks

its not my set, just found it on google
got the scorpion myself, its just on the way from uk to me and I will be getting the scorpion tanks in future too
if you look for the new tanks I think they come without the frame

[Brendan (chem2clean)]

hey Radek,are yo going to be leaving the scorpion in your van like a tm or using it as a porty too.How biz in Cork.
