2016 CDL HOBBY RO, bought new and serviced thru CDL. Comes with 4 membranes. Two brand new ones installed this year. And storage canisters for each of them. Hooked up currently in 220V but could be changed back to 120V. Reason for selling is we are upgrading to a 600. We can send the 2 new membranes to CDL for cleaning, if needed. WE have shipped them for cleaning every year. Canadian Funds
