For the Marauder Pistol (P-rod)  we have designed a special pressure regulator.

The regulator can be used with the original pressure gauge assembly, keeping the gauge in his place. But it is also possible to remove the pressure gauge and gauge assembly completely and replace it with the regulator body, so you have even more air volume available in the pressure tube.
If you use the pressure gauge, it will display the regulated pressure of your pistol.
 

These regulators are vented to the atmosphere without any modification to your pressure tube needed. So no drilling in the tube and also no creeping up in power.

The benefits:

Higher accuracy of your pistol due to the elimination of the pelletspeed fluctuations
A constant pellet speed over the full working pressure range.
Maxiumum use of the air volume due to our ultra compact build.
It will give you a better shotcount and a full flat shotstring immediately.
Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.
Often the rifle will make less noise due to better balance in air usage 


When you order one of our regulators you will receive:

  • Your regulator preset on to your own wishes;
  • A pressure scale in Bar’s on the regulator, for fine-tuning or re-adjustment;
  • We will include a “Huma regulated” breech sticker;
  • Fitting instructions as pdf download

Pressure settings

The regulators come in the standart middle pressure range (MP: 70-150 bar output) covering sub 12 ft/lbs and FAC models.
They come preset on the most common pressure setting, or we will adjust it according to your personal wishes.
It is also equipped with a clear pressure scale label, so you can very easy re-adjust or fine tune the pressure setting suitable to your wishes.


Quality

The regulator is CNC produced out of high grade aircraft Aluminum and bronze.
To guarantee a perfect product, every regulator is manually assembled, tested and adjusted to the requested pressure. 
We only use belleville springs designed for critical applications to achieve the highest repeat accuracy. This gives our regulators a repeat cycle less than 1% difference.

 

 


Before ordering a regulator:
Please make sure, you have made yourself familiar with the fitting instructions on our website, you are happy to carry out the necessary work and you are able to adjust your power to keep your rifle legal.

P-rod in 22 cal unregulated was giving 32 shots 590 -610 fps (2500-1500psi) 3000-2500 psi was unuseable due to low velocity at 3000, and climbing velocity over a span of 50fps in 1st 8 shots, I. E. First shot at 3000psi would be 585fps. This restricted the gun down to just 32 shots.

Now with Huma regulator (with manometer remaining in gun) 40 shots 600-610 fps (3500-1500 psi) with regulator set to 90 Bar. Big improvement!

Things arrived quickly and securely, setting pressure was easy, install was simple!

My goal was about 50 shots or so at 10 FPE w/ 20FPS extreme spread -
utilizing a stock gun, valve, hammer, etc.

From prior tuning, it was known that 110 bar (~1600 psi) would net me 9.5 fpe peak energy (14.3 gr. pellet)

I figured, with the 15.9 gr. JSBs that were most accurate in my gun, I would be well into 10 FPE territory.

Here are my settings and results:

Gauge Block Removed
Hammer: Stock Weight Valve: Stock Config. Transfer Port: Stock (.080")
Fill Pressure: 3000 PSI (206.8 Bar) Regulator Setpoint: 1600 PSI (110 Bar)
Shot String End Pressure: 1350 PSI (93 Bar) Pellet: CPHP 14.3 grain (from tin)
Hammer Spring Tension (From full CCW): 0 Turns
Hammer Throw Length (From full CCW): 4 Turns


# Shots: 49 Avg. Velocity: 543 FPS Extreme Spread: 20 FPS Avg. FPE: 9.36
Efficiency: 12.4 Bar-cc/FPE

For a 50cc airtube (-10cc for plenum, and -5cc for regulator) and factory valve components, I consider this to be pretty great! Maybe later I'll experiment with higher FPE and modified valving components, but for now, time to shoot/enjoy it!

One more thing: I assume that the extreme spread will tighten up a bit as the reg wears in. This was literally the first string after installation!

Very quick delivery..
I placed the regulator just how i was told to do
At least 24 (3 mags) shots very concistently 210 m/s
-208 m/sWith predators 16 grain.

Works great, but a step by step instructions would have been even better.
But now I know what is involved and what to do.

Regulator was easy to install using option B. Tuned to 150 BAR with .028 port. I am satisfied with my shot count, velocities and power . By the way, that pesky air leak from the gauge stopped!

Kevin Kunkle -

This reg works great in my 1720T. I have turned it down to 90 bar with a .114
tranfer port for shooting 8.4 JSB's at 750FPS.
I now have 5 Huma regs.
