Hello all.
Something does not smell correct. Is the rated air flow for a compressor at the rated output pressure; or is it the flow suctioned at first stage inlet ? Or is it outlet flow not filling anything ? Can anyone clarify ?
My 3.5 CFM Kidde used to take about half an hour to fill a tank. 80/3.5 = 23 minutes; about right.
Now, 3.5 cubic feet is a considerable volume at atmospheric pressure = 100 litres ! That is half a '55gallon drum' of air to be pumped every minute !. And a brutal amount of air mass if at 3000psi.
Light, please !
