Air Compressors – What is more important, Horse Power, # of Gallons, or CFM?





I’m reinstalling all the window, door, and base trim in my house. I’m getting a compressor but just curious which specs are most important. I’m looking at a Porter Cable 1.5 HP model with 6 Gallon tank, 150 PSI and 2.6 CFM. Any advice would be appreciated. Thanx.

Need your opinion on air compressors?





I am looking to buy an air compressor for my shop. I am looking at probably around a 1.5 to 2.0 HP with a 25-30 gallon tank. Mid price range. What do you consider good and bad brands?
