This first stage tuning regulator for your FX Impact M3 build by Huma-Air is specially designed to replace the factory FX first stage regulator.
As a part of the Dual Stage regulator system of the FX Impact M3 the first regulator pre-reduces the pressure in preparation for the second regulator. This provides less stress on the second regulator and achieves a more constant output pressure with less standard deviations. Advised is to use about 30-40 BAR difference between the 1st & 2nd regulator.

Although many after market producers make an adaptor to by-pass the original FX first stage regulator, we certainly support FX their philosophy to us a the first stage reg to relieve the second stage reg of the FX Impact.
A good functioning first stage regulator will absolutely improve the consistency of the second regulator and eliminates the small power curve what often can been seen with just a single regulator.


This regulator is a one-one one swap with the factory regulator and also allows you to unscrew or swap the pressure bottle of the rifles without de-pressurizing the rifle.

Pressure can be set by turning the set-screw of the regulator what can be found inside the regulator. Half a turn counter clockwise equals to about 25-30 bar pressure increase. The set pressure can be read on the rifle's pressure gauge.
The Huma-Air tuning regulator will ad 23 mm in length compared to the factory regulator.

Your FX Impact M3 first stage regulator comes preset on the pressure we have tesed it and it is marked on the packing. You can set the regulator according to your wishes within the pressure range.
The output pressure will be shown on the factory pressure gauge of your airrifle.
