Impact Wrench part:: II

THANKS for everybody's response on the first post. Be patient, as I am slowly learning a great deal. I did tak a quick look at my air compressor specs. I have a 4hp (peak) / 2hp (running) with a 25 gallon tank. My question is, will this still work with a 1/2" air impact wrench (425# torque)?
Most will be small at home jobs (removing mower blades, tractor, vehicle lugs, etc.). Also was curious, are the battery operated wrenches jsut as good as air? Kind of like the convenience of not having to drag an air compressor & hose around, but I also don't want to spend an arm & leg. Thanks for our help again & I appreciate everybody's time & suggesions.

Forgot to mention that my air compressor is 150 PSI (maximum)

with the air volume in the 25 gal tank and the 150 psi, you wont have a problem running your impact off it. i have a little pancake compressor that i toss in the truck with the generator for remote breakdowns, and for short bursts, it works fine.

ruatin: as Glennster noted, you can run an impact off from one of the little pancake compressors--I did exactly that while helping a buddy do a brake job on his daughter's car yesterday at his place. The down side is that you end up waiting while the compressor "catches its breath"--fine for a shade-tree job but not acceptable in a shop setting. As I noted in your previous post, the better cordless impacts have pretty much taken over many jobs from air impacts in the last 5 years or so--a trend that will probably continue as batteries get even more powerful and longer-lasting. They've already done so in many professional shops, though that also assumes that they have other tools (larger impacts, long breaker bars, a torch set, etc.) available for really tough jobs beyond the capability of their cordless impacts. They're also more expensive to maintain--more moving parts, batteries to buy, electrical in addition to mechanical components to replace, etc., but the trend is most definitely toward cordless impacts due to their handiness--no cord or hose to drag around is a real plus in a busy, crowded shop and handy in a home setting as well.

for a few seconds it will work, then wait to use again.

Your compressor should have no trouble. I had to remove a mobile home type trailer wheel, filled a portable air tank, took it and my IR impact, removed wheel. Refilled tank later and put wheel back on. 1/2 impact sockets don't use much air. Now an air sander is a different story.

Hi rustin,

I had one that had less capacity and would break a 8/lug nuts loose then spin then nuts off and wouldn't run out of power.
