I just got a shoe box freedom 8 4500psi I'm curious on how long it will take to top off a 66 cubic foot tank 6.8 liters from 3000psi to 4500psi I'm using a 4 scfm shop compressor on it at 90psi
I have a 60 gallon 12 scfm @90psi gonna see if my dad will let me use it... Or I might buy a cheap 5scfm air compressor from harbor freight or Lowe's Ill be filling a small guppy tank and a 45 min SCBA tank
