Frequently asked questions

  1. How do I set up my rifle? On the regulator pages there is a link to an instruction page on the Huma Air website. Here you will find model specific fitting instructions as well as general information about setting up your rifle properly. Answered by Huma Air
  2. Are there adjustment tips available? There is unfortunately no specific advice to adjusting your rifle properly, but Huma Air has provided some general information to understand the principles of a regulator and the settings. Please note, the information the General Air Rifle Adjustment tips in this sheet is broad and and will vary per model and type of airgun. Answered by Huma Air
  3. Is a depinger useful in addition to a regulator? No depinger is required when a regulator is fitted. The PING created by the valve open / close cycle is a sound wave migrating down length of air tube. A depinger upsets/defuses this sound wave eliminating most the ping … a regulator is a complete wall to the sound wave stopping any ping nearly 100%.  Answered by Motorheads Air Gun Tuning Services
  4. What is the warranty on a Huma Air regulator? Warranty covers material workmanship only. O-rings are excluded due to the fact they will wear or can be damage during fitting. There are no other parts which can really break. Occasionally a regulator can creep a bit in pressure. Flipping over the white valve disk will probably solve the issue. Answered by Huma Air
  5. Are rebuild kits available? Yes, rebuild kits are available. As long as you open up the regulator at the back side with the C clip, the setting stays the same  and you can service, swap o-rings. When you want to unscrew the set screw, alway measure the total length of the regbody + screw so you can screw it back together in the same length. Please follow the regulator revision manual. Answered by Huma Air
  6. What are common factory settings? For the average FAC rifle in .177 it is around 125 bar and for .22 caliber it is around 130-135 bar. Average set pressure for .25 is 140-145 bar. Answered by Huma Air
  7. How do I set or adjust the pressure? A manual is available for download on the website on how to adjust the pressure of the Huma air regulators. In between the slots of the set screw there is a very fine mark (click here for photo) on the side of the set screw indicating the right pressure. Answered by Huma Air
  8.  Are regulators all the same size? The .25 caliber models are about 10 mm longer when compared to the .22 caliber models. .30 calibers will be even longer. Answered by Huma Air
  9. Can you fill “upstream” from the regulator? A regulator can only let air through one way, from high pressure side to low pressure side. So in case of S200 or CZ200 a quickfill on the other end of the tube is necessary. Answered by Huma Air
  10. What to do if my regulator creeps a bit? Flipping over the white valve disk will probably solve the issue. Please follow the regulator revision manual.
  11. Is the CZ200 12 ft lb (Low Pressure) and the FAC (High Pressure) regulator the same, only set differently? No, the low pressure has a different spring packet and is set to 90 Bar with a maximum of 110 Bar setting. The FAC version comes set at 130 BAR. Answered by Huma Air
  12. My BSA isn’t completely sealing, what should I do? BSA air cylinders may have fine lines causing the o-rings on the regulator to not seal. These lines will need to be polished smooth. Answered by Huma Air
  13. Is there a lag time from shot to shot to allow the regulator to repressurize? The regulator is 95% refilled in the “blink of an eye”, the last few bars take a few seconds. Answered by Huma Air
  14. I’ve over or under adjusted my regulator. Now what do I do? They over all length of the regulator should be around 36.4mm Click Here for a picture.
  15. Will the Disco or Maximus regulator fit the Prod? Yes it will fit, but the plenum is bigger so you lose some primary fill pressure. and you can use bit lower regulator pressure setting. Answered by Huma Air.
