You can find their distributors network here.
Just scroll down, there are some both in UK and Spain.
The company is not far from where I live, I can give them a call if you need further details.
PS: how old is yours? I have a similar one, 12 years old, never missed a beat so far (fingers crossed!).
Thanks Mario. I will try the UK suppliers first. Mine is 8 yrs old but I had to have the electric motor rebuilt a few months ago and the belt has broken a couple of times which I think is due to failed bearings and the unit is now very noisy. Rather than keep getting it repaired, I've decided to replace it, if I can. We have had regular gas leakages and the compressor has been working continuously because of this so I think it's had a hard life although it's still disappointing to have to replace it
Well, mine also is rather noisy (always been, actually).
But it's in the engine room, and thick wood does a gorgeous job as insulator, also for noise!
Though now that you mention, also mine is taking longer before turning off, lately.
It might well be that it also begins to leak some gas.
But I guess I can't complain, 'twas never refilled in 12 years....
