would it work to attach the outlet of a 100psi compressor to the second stage inlet instead of having a first stage?
also i dont understand floating orings so if some one could help me with that it would be great!
Floating o-rings are simple. On the downstroke they are forced against the piston, sealing the chamber and compressing the air. On the upstroke the o ring has a small amount of movement and travels down, allowing air from around the piston into the cylinder through a gap.
By doing that you run slight risk of pneumatic ramming but it would be workable.
