I recently bought a new compressor that has a tank (3.5 gallon). My old one was a tankless compressor that had a pressure switch as part of the hose. I always used to set it to 10-15 lbs. The lowest setting on the gauge on my new compressor is 20. Is this too much? I want to call the company and find out what they suggest between 0 and 20 as the appropriate setting to achieve around 10 lbs pressure. Too close to 0 and hardly anything comes out. I've never worked with a compressor that has a tank and regulator control and don't want to use too much air that could possibly damage the lines in some way. Thanks for any suggestions.
