Had new Daystate 4500 compressor almost a month now and here are some stats for filling my Omega 75 tank. At this rate the compressor will outlast me by far prior to needing a rebuild. Compressor was a lot of money but I'm very pleased.
--- initial Omega 75 tank fill from 0 psi to 4500 psi (310 bars) took 21 mins. (discharged water twice).
--- filled FX Royale 400 5 times from 150 bars to 220 bars (larger 480 cc bottle on FX 400)
--- filled FX Tarantula 1 time from 100 bars to 200 bars (not sure of Tarantula bottle size)
--- filled Omega 75 tank from 200 bars to 310 bars took 5 mins (discharged water once)
NOTE: Tank was quite warm after initial fill so the pressure likely dropped after tank temperature dropped to room temperature but did not record.
