Some observations today when testing my 2 tanks...
There is a difference between high flow and high recharge. Some companies like to use this interchangably. Although they are related they are diffrent.
The test...
AA Raptor Rex 4500
vs.
Centerflag 200 (Same internals as ALL Centerflag Adjustables.)
The dyno:
Automag RTP, LX, Input 1000 psi from both tanks. Chronoed at 250fps. Hooked to a gauge 0-1200 range. ROF ~23 bps give or take.
The centerflag reg I have concluded is a high FLOW reg. It however has a slower RECHARGE than the AA.
Under Rapidfire conditions the automag RT produced a drop of 200 psi from 1000 psi as indicated by the gauge. When the gun got going the pressure dropped and STAYED at 800 psi. Until I stopped shooting then the gauge went back to 1000 psi. At no time did the pressure drop below 800 psi from my observations.
The AA reg is a high RECHARGE reg. It however has a lesser immediate FLOW than the Centerflag reg.
Under rapidfire at 1000 psi. The gauge jumped between 600 and 1000 psi with every shot. It was bouncing around like a tennis ball. The reg never STAYED at lower than output setting. The reg ALWAYS fully recovered from each shot to 1000 psi BEFORE the next shot was fired.
Conclusions.
The RECAHRGE rate of the AA was much faster than the centerflag reg because it was able to recover FULLY after each shot. However the reg had less immediate FLOW... the floor of the pressure reading was 600 PSI vs. The 800 PSI floor of the centerflag. However its speed of recovery made it possible for the reg to output 1000 psi the split moment before each shot.
The FLOW of the centerflag reg was greater because the IMMEDIATE pressure drop was lower showing a floor of 800 psi vs 600 psi with the Raptor. However the recharge rate was much SLOWER as it failed to recover fully to 1000 psi like the Raptor had. The centerflag reg hovered around 800 psi under rapid fire relying on its flow to keep up the gas demand under rapid fire it never recovered to its set output at 1000 psi.
