I have a four year old GB5 AV 3 group machine for sale.  I will replace all the flow meters and do a general maintenance of the machine before sale.  In good condition.  Detergent back flush cycle is run every day.  I just had to replace the CPU so there shouldn't be any foreseeable issues in the near future as long as it's properly maintained.  Asking $9000 or best offer.

The reason I'm selling is because a 3 group is major overkill for our operation.  Looking to buy something smaller that better suits our capacity.  Email me with any questions.
