Compressed CO2 “Works Better Than Air”

Compressed CO2 “Works Better Than Air” FARM SHOP Miscellaneous Whether using an impact wrench or just filling tires a 10-lb 1 8-gal Power Tank filled with CO2 equals the useable air in forty 10-gal air tanks Steve Sasaki says his Power Tanks are the perfect answer for adjusting air pressure or making repairs out in the field     “When I started 4-wheeling in 2007 I learned about the advantages of raising and lowering air pressure depending on what you’re doing ” says Sasaki “I could buy a compressor for under the hood or one that ran off the battery I didn’t like either so I came up with my own system ”     Sasaki’s Power Tank system makes use of the fact that CO2 is significantly different from air It will pressurize to a liquid at normal temperatures at a pressure of 870 psi at 75 degrees     “CO2 is more dense than air and continues to generate head pressure even when the amount of liquid is near bottom ” says Sasaki “It stays at 870 psi until it’s all gone ”     Developing the Power Tank required developing a special regulator unlike those used in welding or for other purposes It’s designed to release CO2 vapor without “freeze clogging” or damage to components from sub-freezing temperatures It also offers high flow as much as 40 cfm This means that downstream components have to be high pressure as well     “I can run a 1/2-in impact wrench off my 1/4-in braided hose ” says Sasaki “We have a much higher push pressure than an air compressor tank does ”     Sasaki says getting refills is easy He suggests taking tanks to fire extinguisher stores welding suppliers and others The tanks do not have a meter on them indicating remaining CO2 notes Sasaki     “A 10-lb tank will refill between 16 and 20 tires ” he says “You can weigh the tank occasionally or just keep track of how you are using it ”     Power Tank offers 4 levels of air systems all featuring SuperFlow regulators Depending on the level regulator flow can range as high as 400 psi Models include a 20-oz 2 1/2 5 10 15 and 20-lb tanks The size indicates how much CO2 it can hold when filled Power Tanks start at $149 95 for the 20-oz Power Shot A 20-lb Power Tank is priced at $429 The best selling Power Tank is the 10-lb system The base price for it is $389 95     Contact: FARM SHOW Followup Power Tank 43 Commerce St Unit 103 Lodi Calif 95240 ph 209 366-2163; www powertank com
