[QUOTE="Nightjar, post: 665657, member: 1414"] Have mentioned in another post Somewhere around early 90's we did a comparison between continuous air and bellows type dry blowers, the bellows/ puffer design won hands down. The main comparison was we re-ran tailings from each machine back through opposite machines. The continuous air rarely picked up any gold from the bellows tailings, where as the bellows retrieved a surprising amount of gold (fine) from its opposition. These weren't one off tests, they were over a month period. Here is a little info on the patented bellows.
