Do you need to seal the collection bin ? I would have thought it was negative pressure?
My rubbish bin with 4" fittings works well. The big problem is it keeps filling up!

Hi Guys
I think that the critical issue is that the whole system must be air tight - any leaks will reduce the vacuum - and it is usually easier to seal round corners than square.
About twenty years ago I got four brand new (unused) 20 litre steel ring lock drums from a local paint manufacturer. Earlier this year I tried to get a new pair but they declined to sell to me - "group rules". I did note that the steel in the current generation is much thinner than it was 20 years ago. This may be relevant. Will the drums collapse or buckle under vacuum????
Cheers
Graeme

I'd be quite pleased if they started selling these with 150mm inlets and outlets!
