Airguns / Impact wrench for tire removal

[Ken DeSerio]

I am looking for information as to what airguns or impactools are used in the pits for changing tires. Please advise manufacturer or brand/model. Our company is interested in getting into CART / Indy type racing.
Thank you

lots of teams use an Ingersoll-Rand model- easily found and ordered through websites.
Also company named models are out there- Klein, Beta, matco, SnapOn,Mac-
hunting on some race parts sites might reveal something as well.
I figure price would range (my normal impact was $310Aust.
so figure on 270-450 dollars US. The nifty titanium ones are really light but, expensive.

also try look for used equipment from various teams or their websites.

Best bet,approach a team to "sponser" supply them with guns and then improve the breed till everyone follows them to your product.Pick a team that is willing to work with you and be prepared to have your guns used during practice and parked during the race untill their performance is known an reliability up to spec.It may work on the bench fine but watch a race and note the front wheel guy toss the thing 2 meters across pitlane and someone drag it over the wall by the hose and you will see what i mean about reliability.
Good Luck

Don't a lot of people use nitrogen to power the guns. I think its because of the less expansion which makes them more accurate when set to a specific torque using those torque attachments which are supposedly a little iffy with compressed air

Well the nitrogen is used in the tyres to maintain a better start pressure due to less expansion of the gas under heat and infact medical spec nitrogen is even better as it has nil H2o in it(water expands)so you start with a higher pressure,using a vacum pump to completely empty the tyre first gives an even better result.The use of nitrogen in air guns is ususally just convienient as you don't have to cart around a whole heap of different bottles..
PS pure oxygen in air guns = big explosion inside gun and trip to hospital for operator

many gun guys do use Nitrogen tanks to power the guns as there is no worry of internal damage over a season (no water on moving parts) so they go this route to have a consistent non jamming gun
