What's everyone use to fill their PcP's

Alkin W31 Vertical compressor and have 3 60min/98cf tanks. Cascade fill with two of them and rotate out the lower pressure of the two for my third that's always topped off and ready when it's time to refill the lowest tank. I NEVER have to wait on air that way. It's bliss.
Same here, but 2-45’s and 1-60 minute, and cascade the same way.
