With how I have my compressor and the booster set up in just under 2 hrs it put in 700 psi. I have a husky Oiless compressor that’s about 10 yrs old. 20 gallon tank 1.9hp motor 4.3 gallon per min at 90 psi and I have it set regulated at 90psi. Could go higher but no need to for my use. You need to play with the input pressure screw to get the right amount of air in there so that my drive compressor runs for about 5 min and shuts off for 2 or so. The thing is really quiet i wish my compressor wasn’t so dang loud you would barely be able to hear it in another room if the drive compressor is off. Close the lid then it’s very very quiet. It’s so simple yet well built I’m very satisfied with it so far. Only been running it for 2-3 hrs at a time but not cause the Altaros but so my compressor don’t die on me. Should get it all the way filled by tomorrow.

Yeah it is they say you want to try to get it to a 60/40 run time/off time. Keep in mind though it's not very efficient I probably need to upgrade to a new one
BTB, he is only running the primary compressor at 90PSI, so I would expect it to cycle on and off a lot more frequently. You say that 700 PSI in 2 hrs sounds about right for the Shoebox F10, I'm assuming that is from 0 fill, and a similar size compressor, cycling at 90PSI. One thing to remember the higher the feed supply pressure and volume the quicker the fill times. thanks,Ken

I would think that if he were to increase his output (both pressure and volume) then his compressor would stay on even longer, no?
I was talking generalities not just DB's small compressor. Yes, if he increased the output pressure it would have to run longer, but would hopefully in turn cycle on and off less frequently. I don't quite understand why Altoros is suggesting having the compressor run at a 60/40 cycle? Unless it has something to do with maybe heating of the air in the compressor before it goes to the booster? Maybe condensation?
...The real advantage is the Altros is a true booster pump in the way it is operated, as it requires NO power source from an electric drive or gas drive motor. The same input compressor both supplies firstage air, and drives the pump....
