Got my Compressor from a friend... Its an old school unit... Double piston, Cast Iron Pump.... 50 Lbs with nothing on the pump... LOL...
Rated for 7-8 CFM at 90-100 PSI.... Thing works great and recovers incredibly fast for its size and age... 17 Gallon... The Pump is said to be good for 50 years... and they have never changed the design
I have a 25 gallon 3hp craftsman, rated at 100psi 12.5cfm.
It works great but have to give it time to recover when in heavy use, ie impact gun
Its a good size for home use, not perfect in every situation but the price was right and it has'nt let me down.
