I would recommend using them to help save your compressors, especially if your running Firestones. Viairs come with an inline check valve, but the Firestones don't.
I could have used a check valve in front of my compressors.I have 2 firestones and when they went bad, they started leaking and I would lose all air pressure over night. ~
