Just a couple questions.

What are ya all using for compressors? What has worked well for you that has been reliable? Rocking piston and regen I have are way too noisy in the basement and don't want to go thru the time and expense to hush them up.

Retention time. Anyone figuring that in? I don't think it's too critical on lightly loaded systems with excessive media, but they tell me a minimum of 10 minutes.

Thanks!!
