Huma pressure regulator for the Air Arms S400 S410 S500 and S510 airrifle.

For the Air Arms S400/S410/S500/S510 models  we designed a regulator what can be placed inside the pressure tube. There are two o-rings on the regulator body who seals inside the tube wall.

The regulator is vented to the atmosphere for excellent regulating behavior and no creeping up in power on the long term.

The regulator has a seperate volume bus (plenum) matching the caliber and preferred power.
The regbody is only 16 mm long and the regulator neck is round 13 mm with a length of 15 mm. So there is almost no lose of air volume in the pressure tube.
A simple modification to your air rifle what will result in excellent shooting behavior and very consistent pelletspeed.

The benefits:

Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
A constant pellet speed over the full working pressure range.
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 

Pressure settings

The regulator comes 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.

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

 
Quality

The regulator is CNC produced out of high grade aircraft Aluminum and bronze.
To guaranty 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.
