Good to hear from you.
This unit was I must admit purchased from EBay.It is a water based one with nebuliser and voltage regulator.
I however adapted the unit by removing the exhaust outlet and fitting my own copper 15mm fittings.The copper pipe passes up thru the superstructure and funnel.
I attach a flyer from the builder.
It is very effective.
Somewhere I have a video which I will look out and post.
I have subsequently built my own after buying all the components individually.
