Power Tanks are used for more than just airing up tires and reseating beads. They are the best air source for your tools because they don't require power so they're silent and you don't have to run power lines.
All of the air tools we sell, we run on our own rigs and in our shop. Our IR 231 impact wrenches are the workhorse found in tire shops around the country. The Chicago Pneumatic impact wrench is a little lighter and a little quieter but still packs a big punch.
Our high pressure blow guns are the only ones we've found that can handle 400 psi and 45 cfm of air without breaking. The bendable tip option was added when Steve was at the Baja 1000 with JT Taylor and noticed that the pit crew had a tough time blowing out hard to reach radiators and belts.
