Reduce, Reuse, Recycle, and Save Money
We can go through a lot of tennis balls, particularly since we use a Slinger Bag. We were looking for a method of extending the life of the tennis balls and found the Pressure Refresher. We bought the Pressure Refresher keg and a 10 pound CO2 bottle that we fill at a welding supply store. The system works great. Used balls are restored to near-original condition--I can't tell the difference-- after three days in the keg under 40 lbs of pressure with CO2, and they are maintained by keeping them in the keg under 14-16 lbs of pressure with CO2. Rather than going through hundreds of tennis balls per year, we are able to get used balls from our club that are destined for recycling or the trash, refresh them, and play on. We have told our tennis-playing friends about it and hope to convince our club that they should consider this option.
