It is possible to connect a PTO drive to most vans and it will run a compressor. The units are fitted under the van and can run all air tools including inch drive guns.
yes i always blow breakers with my 110 i have to take it down to almost nothin in the tank before i turn it back on
when i forget to turn it off 9times outta 10 ill blow a breaker when it kicks back on and to do blow outs i only need to let it fill up once and start blowin b4 it reaches the shutoff psi lol
big pain in my rear
cordless impact was worth every penny
The problem with any 110 volt compressor you could put on your van that would run a 1/2 impact is this: you would need a 20 amp outlet to run it. You will probably be at a dock door with a 15 amp outlet that is 500 feet from the breaker box. It will never start the compressor once it trys to kick on with 80 PSI in the tank. All of my dealer's van have gas compressors. It is either that, or use the breaker bar and the 18 volt impact.
I have always used gasoline powered hotdogs in my full size van, never had problems with space. If you are overcrowded you are simply carrying too much inventory or redundant tools in your truck. Try leaving more of your duplicate parts at the shop, you will find this saves you on fuel costs as weel. I have less than $7K in inventory in my truck.
i loosen forklift tire nuts with a 3/4 breaker and use my dewalt 18v electric impact wrench to spinn em off in most cases takes less time to hook up the compressor (wich is a craftsman 110v)
big big tires as in marine units (10 ton and up) we subcontract a tire place to jack, block, and remove the tires since they have trucks with 2 stage compressors and 1 inch guns ready to go
my electric impact cost me like 300 on amazon i love it
CFM is more important than PSI. I agree a two stage would be the best but, I think you are looking for compact size to fit in your van. You may consider a 3/4" to 1" breaker bar just to loosen and tighten wheel nuts. If you go that route you can use your 1/2" impact to remove and install wheel nuts. Then you might get by with a smaller compressor.
If you are going to work on forklift truck tyres, then you'll need more than 100psi. You might be looking at a 2 stage compressor.
Richard; MSC.com has several electric portable air compressors available. A 1/2" air impact will need between 4 & 8 cfm @90-125 psi.
