just set up my 450 from Pure Freedom. Looks incredibly similar to my 300.   

Is there a way to tell them apart? Are the membranes the same size?

Both have three membranes.

Anyone know?

MEMBRAINS INSIDE WILL BE A DIFFERENT SIZE IE 100GPD NOW YOU HAVE 150 GPD,X3 +450 GPD

I hope so

The 150 membrane is larger that the 100 membrane.

I thought about it but I haven't needed one for the last five years and it would have meant buying more fittings etc to link everything up. So £600+ or £235 to do the same thing?
Couldn't justify it in the end, I'd rather invest my money in spare sections for my xtreme poles at the end of the day.

Looked at the twin booster pumped units online from reach to wash and Vyair.
Crummy customer relations on both I felt.
Vyair shut the office at four and were out of stock and John Hewitt couldn't give a toss if he sold something or not 
Out of stock too.

I dont know what ro you have but have had both 100, 50, and 150 and the reason I know is i tried to fit 150s in to my 100 unit and I had to upgrade to to a 150 canister.
 It would be most helpful if you could justify your remark so we can learn from you wisdom.
