What cfm is required?

Alot. 56 cfm. 1/2 inch airline with ALL half inch fittings if you want max power

What is the lowest psi requirement in order to work?

Thank you for your inquiry. The lowest psi to run this tool, is 90 psi.

What type of compressor is required for optimal use? Im considering a 14HP 30 gallons

I have 2 5hp 80 gal 2 stage compressors hooked together and this gun will make both kick on .it is strong but uses a lot of air. Doing 10 1.5" bolts requires me to slow down a bit or both tanks will draw down to where the pressure is insufficient for max power.

being light weight, but is it still durable like the heavy duty 1" gun?

yes, please reach out to our Tool technical team for complete details and specs on this model. 800-483-4981 option 2 then option 1

Yes this gun is awesome!!!

I'm a heavy equipment mechanic and I purchased this 1" drive impact to remove excavator counter weight bolts, rusted track pad bolts and Volvo A30 hull truck lugs. Let's just say I'll never need to borrow the 1" community shop gun ever again! This thing has some amazing torque and seems built to last a very long time. My service truck has a 3/8" air hose that I run all my air tools with but I've added a second 1/2" hose just for this beast! It works perfectly! I'm pretty sure Ingersoll recommends a 3/4" hose for this impact but that's an awful big hose and I'm not to sure how my compressor would keep up with that. I would say I'm still getting 99% of this impacts torque with the 1/2" hose though. This gun is still weighty but compared to other 1" impacts in the same class it's extremely light weight. I also love how I can position the handle in any position needed for the job. I believe this gun is now tied with my Milwaukee fuel 3/4 impact for favorite tool! Love my Ingersoll air tools and my Milwaukee M18 battery tools!! Ingersoll Rand's 2850max is a 5 star tool all the way!!!!!

More power then the Chicago Pnuematic Wrench it replaced

It is lighter and more powerful. Have to wait and see how long it lasts.

Powerful

Worked great to remove rusty axle nuts from my farm disc axles. Other than a blast of air that can be annoying when it finds your eyes it's a great product.

Weak

Don't but it. I'm not sure if it's made cheaper on here or what but it is so weak. Wish I could return it still.

Lightweight and powerful

Lightweight gun, not as noisy as the other ir 1” impacts. The only thing that bothers me is the handle can be placed on either side of the impact but it keeps loosening up for some reason have to tighten up after every use and it’s a little annoying other than that it’s a great impact.
