As the title states. I'm looking for a compressor that will lay down flat under my bed cover but has the CFM to run my air polishers (6CFM @ 90 at least) Small pancake compressors can't do this, horizontal's don't fit under the cover, but vertical 15 gallon compressors can do this. and they are like 19" laying on there side. This is perfect for a bed, but I don't want to have to put it upright when I get to a job, I want to be able to just hook it up and go. Has anyone had any adverse effects from laying a compressor on it's side? Google still left me guessing.
