Huma-Air external Air Arms S200 tuning regulator for the Air Arms S200 airrifle.

The Huma-Air regulator will regulate the air pressure in your S200 airgun. It reduces the primary high fill pressure in the cylinder into a  lower pre-set working pressure. This will give you a constant pelletspeed and a higher accuracy; no more compensation on the (H)FT lane!
The installation of the S200 regulator is very simple. Unscrew your air cylinder, screw the regulator between firing valve body and pressure tube and you are ready*
It is vented to the atmosphere, so no creeping up in power during time,  without the need of a breath hole in the cylinder.
A simple modification to your air rifle what will result in excellent shooting behavior and very consistent pelletspeed.

* To fill your rifle after a regulator has been fitted, the pressure tube needs to be filled from the front of the tube. If your rifle does not have a front fill connection,
we have 2 optional front quickfill units available, a quickfill unit with front pressure gauge and fillprobe or a basic quickfill unit with a foster male fill connection.


The benefits of this Huma-Air, Air Arms S200 tuning regulator are:

  • The regulator housing is made of extremely tough 42Cr steel
  • Tested for a working pressure of at least 3x the working pressure of the rifle, for everyone’s safety
  • A constant pellet speed over the full working pressure range
  • Because the regbody comes between tube and valve you will get 45 mm. extra airvolume
  • The regulator body and the housing are one piece, so no chance of the regulator moving inside the cylinder
  • The one piece body and regulator housing also reduces the possibility of leaks
  • DIY fitting is a real option for the most people
  • High quality bluing in the same matte color as the original pressure tube
  • Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
  • 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.

Due to his length this reg has a restricted airvolume, so this makes it specialy suitable for the 12 ft/lbs – 16 Joule versions. The maximum power of the reg is about 20 ft/lbs – 30 Joule.
The regulator adds about 46.5 mm of lenght to the cylinder. Because there are many different lengths of cylinders and barrels, it is advisable to check whether this does not disturb the placement of a silencer.

Recommend absolutely

I haven't received my reg and the tracking doesn't work. I have contacted huma and they can't track it either.I hope someone can help as I can't use my rifle. As you can imagine I'm not very happy with the situation.

Jeremy - 26-08-2021 23:34

Installation very straight forward, hardest bit being the dismantling of the end fittings in the S200. Cleanliness is vital but if you follow that rule it works very well and no leaks.

Simon - 13-01-2021 10:30

An excellent upgrade for me S200. Installation is simple and straightforward, and together with the Huma quick fill and gauge it is great.

Ian Blakeley - 31-10-2020 09:20

Excellent regulator, fitting very straightforward once I had overcome the difficulty of removing brass end from air cylinder. Would be much harder still without special tool, still had to heat up with hot air stripper. Delighted with the result, much improved shot count.

Pete in Reno, Nevada - 01-06-2020 03:00

Very pleased with the Huma external regulator for the Air Arms S200. The installation was easy - although unscrewing the valve from the air reservoir would have been impossible without the special tool. Excellent velocity regulation with improved accuracy and higher shot counts. The Huma unit seems very well made and it functions flawlessly.

Great product very happy

Ian Causton - 01-01-2020 11:37

Superb unit, high quality, easy to fit, totally consistent shot count now.

Ian Pryke - 07-12-2019 18:47

Very easy to fit and had transformed my gun. Thanks

Nick Mawson - 21-06-2019 00:36

The most difficult part of fitting the regulator was removing the valve from the cylinder - once done the regulator is a simple job.
setting up using the instructions seems to have worked very well.

David Baker - 10-04-2019 19:07

The regulator I received from you was excellent in both quality and Performance. I would have liked more information about setup.e.g. air Arms s200 firing pin settings. I could only find the settings for sub 12-ft lb

Mike Gleeson - 13-02-2019 16:51

Bought this to even out and extend the number of shots in my S200 Mk 3. Once installed the Huma seems to work fine, although I've only put about 100 pellets through it since installation and I'm told it need a couple of hundred to settle down.

Actually fitting the regulator was simple. Getting the air cylinder apart to fit it was another matter entirely. My cylinder seems to have been tightened way too much in the factory, as it took a set of mole grips on the cylinder to crack the seal, marking the tube quite badly in the process. So be warned. If you want to keep it perfect, maybe let a gun tech split the air cylinder for you.

Easy to fit spot on

John Francis - 23-11-2018 08:36

Regulator arrived promptly, in perfect condition as you would expect. fitting was very simple with no special tools required. I am now a very happy customer with a shot count of around 90 at a constant 11.7 ft/lbs, I thoroughly recommend fitting one of these regulators.

Andy Morgan - 13-07-2018 17:19

These regulators are a top notch product, easy to fit and improve the shot string no end highly recommended

C.J. - 23-03-2018 08:50

Bon service, livraison rapide et très facile à installer.
Les premiers essais sont prometteurs sur la AA S200.
Il ne reste plus qu'à faire les réglages définitifs.

John Collins - 21-11-2017 17:08

Good service, prompt delivery, can't complain. Can't use the product just yet as it is a Christmas present.

d.j. - 26-09-2017 12:19

Shots within acceptable parameters. Will probably settle down a bit more with continued use. Although I use heavy pellets notice at least 15 extra shots per fill.
Satisfied with product.

Smithy - 21-09-2017 16:26

Like it very much .

HParodi - 20-02-2017 14:11

I installed the HUMA external regulator to my CZ200 and it fit perfect. This weekend I participated in the West Puerto Rico Field Target Grand Prix in Puerto Rico and I can tell that there is a big different in shooting with and without the regulator. I got more shoots and wasted less time refilling in the competition. I recomment to anyone to install one of these regulator to its air rifle.

Biagio - 19-06-2016 09:16

I bought the external regulator for my AA S200

Hi, I have to say that this regulator have flipped my airgun world up-side down. It has given me at least 25 extra shots that makes me shoot way more. Consistent shot to shot string. I can actually shoot my rifle in for Field Target, yard for yard. I have to say, I don't like the Huma Regulator, I love it very very much
