While I will agree in part His plumbing Could have had restrictions reducing flow, removing those restrictions will increase flow but not beyond what the Pump can put out.

Just like using Hi flow quick disconnects increase air flow to guns, Bigger hole more flow.


Just out of curiosity I went on You tube to look for these cfm calculator deals for the heck of it, I found this video EVERY ONE SHOULD SEE THIS! Catastrophic Tank failure!

WOW! Cant say more about using auto drains! Tanks should be drained daily.
Even that little Tire filler can be dangerous never seen one do this before.

Yep, first thing I installed on our new compressor was an auto drain with timer. We've always isolated compressors from our work areas as well. I was surprised that someone didn't get seriously injured in that video.....

Wow. It is amazing that he didn't get seriously hurt.

Wonder what brand of compressor that was? Tank walls did seem pretty thin.

It was a Husky he made a few videos of it, Analyzing stuff.
Emergency blow off valve was working after he pulled it off and looked at it, although at the time it exploded it could have been plugged and the explosion could have cleared it.
I don't know.

I don't know but it all seams a little fishy to me? That took a lot of force to do that.
Almost like an internal explosion, if the Tank was rusted out it would just start leaking air.
This is a Total catastrophic tank failure.

I was at an equipment demo for sanding put on by National Detroit many years ago. The rep. was emphasizing how important CFM, correct pressure, high flow fittings, and all that stuff was. He was also pushing that you needed a pro quality compressor set up to achieve the best results with their equipment. He had some bits and pieces with him of just how inadequate almost any portable compressor from the big box hardware stores really was..... he had a few cross sections of tanks, seeing how thin they were was enough for me. From that day on I never took a portable compressor on to a job site, opting to use our turbine systems instead.....

Did we loose the OP back at the CFM calculations?

I know it probably wasn't what he was hoping to hear, but we told him the truth.

Nah, last visit 21/12 at 9:23. So it was PD, with his Tekna recommendation, that scared him off. :knockout:

I'm hearing everyone say that the cfm wouldn't be changed by the increased diameter of my plumbing, but why would the increased size of the regulator decrease the orange peel/spattering effects i was yielding. Oh, and I'm not arguing with any of you, just trying to understand. Thanks a lot for all of the input.

CFM output is controlled directly by the compressor's pump. If the pump is only putting out 12 CFM, is not going to make more because the pipe diameter is bigger.

Increasing the pipe, fittings and regulator diameter will allow more CFM to flow through them, but it will not increase the amount of CFM available.

Think of it this way. Say you have a water pump that put out 15 gallons a minute and it was going through a 1/2" diameter hose. The amount of water going through that hose would be limited and under increased pressure. So you put a 1" diameter hose on and the pressure decreases and more water flows through it, however the "amount" of water is still limited to 15 gallons a minute because that is all the pump puts out.
