Up for sale is my Danner AP-60 air pump, and BNIB diaphragm rebuild kit, purchased new by me about 4 years ago. Asking $150. I ran up to 25 tanks, and had over 40 outlets on it at one time. It was rebuilt on Aug 8/16, so should have another couple of years before needing another rebuild. Takes about 30 mins to rebuild it. Only downside of this pump is that it is fairly loud, but I have not heard a piston pump running to compare, and this is in my garage so it doesn't bother me. Pump comes with it's original 14 outlet mini bar, or for $1 ea I can sell you some SS air outlet valves you can thread into 3/4" Pvc pipe. Pm your #, and I can text you some pics, or look up on Amazon.ca. Looks exactly the same. This is still running in my garage, so you can hear it in action. No delivery. First to pm me gets dibs for 24hrs, then on to the next pm. Pretty firm on price. Cheers, Chris.
