In my little play house (man cave)
There is a 7.5HP 80 gallon Speedaire compressor.
CFM is what you will be concerned with.
90 CFM should be the minimum for your choice.
Running a DA will chew up alot of air FAST !!!
Recovery is essential. Your choice of air tools IMO
should be a good finish gun IE: Binks or Devilbiss.
You need a "BS" gun for primer or PVA, Harbor Freight
quality would be just fine for that gun. A "whiz wheel"
as I call it for cutting up decking or any thing else that gets in its way is a must as well.
Be sure to get a water seperating filter as well.
Blowing the compressor off of all water in the tank is a must.
Check Craigs List and other sources for deals that are a plenty every where today.
See ya, Ken
