How long can potatoes be stored in an air-conditioned room?

We process 500 lbs of potatoes three weekends in October each year for our Oktoberfest celebration. We store the potatoes in an air-conditioned room at about 75 degrees. At my home, potatoes can last up to a month sitting on my kitchen counter. Can the same potatoes, in a 50 lb sack last for two weeks before we boil them for our potato salad?
