I prefer to use a linear compressor; low cost to run, low pressure/high volume. The only brand to purchase is Hi-Blow.
I run mine on a thermostat .... on at 34 and off at 40 (+/-). I turn the system on in early December and off in late March.
The lines do sometimes fill with water when the compressor is not running. But it has never been a problem. Because the lines tend to float when filled with air, I keep the lines weighted down with rocks & bricks.
Once a summer, I make a feeble attempt to wipe the accumulated 'growth' off the lines.
I've doing this for 21 years. I think I've rebuilt the compressor 3 times; Hi-Blow sells a rebuild kit.

Thank you so very much for this description. One further question, do the lines stay completely free of water during run time or does compressed air make it's way through a tube that is filled or partially filled with water? Thank you.
