This FX Crown regulator by Huma-Air is specially designed as a "one on one" replacement regulator.


Unfortunately the fixed limited space in the FX Crown action was not sufficient for our standard Huma-Air Regulator design, so we had to comply our design to the ratio's used by FX.
Never the less we have accomplished to make a great replacement regulator what will solve the know issues of the factory regulator.

Currently we have 2 models available, a version what can be identified by a 15 mm long piston what is compatible with factory models with 14 mm and 16 mm long pistons and 8 mm bellevilles disk springs. And a  version what can be identified by a 16 mm long piston what is specially designed as replacement for the models with a 16 mm factory piston and 8 mm Belleville disk springs, this model is not backwards compatible.

So what can you expect of the Huma-Air FX Crown Regulator:

The output performance of the Huma-Air Crown regulator won't be very different compared to a good functioning FX factory regulator, but we have some other benefits available
The recovery time in between shots is much faster compared to the factory regulator.
This Huma-Air FX Crown regulator can be adjusted higher in pressure from the outside while the rifle is under pressure.
Equal as the factory reg, if you want to lower the pressure, the rifle needs to be de-pressurized first otherwise the valve get damaged.
By using another type of material for the valve and piston, there is no way you can damage the piston because of faulty pressure adjustments.
We also supply some extra valves, so in case you adjust the pressure to the wrong side, and you damage the valve, it can be replaced without any extra costs.

Model selection:

FX Airguns uses several models of regulators in the FX Crown. We have replacement regulators for 4 of the 5 models.
In the orderfield you can select two models:
  • An Huma-Air regulator as replacement for a factory regulator with a 14 mm black plastic piston.
  • An Huma-Air regulator as replacement for a factory regulator with a 16 mm long plastic piston AND 8 mm diameter belleville spring disks. 
  • A factory regulator with a 16 mm long plastic piston AND 10 mm diameter belleville spring disks is currently not compatible with our regulator models.
    This model is produced after 3-2018 and probably has a serial number above 183534


Pressure settings

The design of the regulator makes it posible for setting it exactly to your wishes while placed in you FX Crown by watching the output pressure gauge on you rifle.

We have three pressure ranges for the FX Crown regulator available:
The High Pressure range, 80-150 Bar, what will suit all calibers within the normal FAC range.
The Extra High Pressure range, 145-190 Bar, when you want to have extreme settings. Please note: raising the pressure above the factory set pressure is on your own risk!
The Low Pressure range, 50-90 Bar, specially for sub 12 ft/lbs models.

Please note: you need to do the stacking of the belleville springs on the piston yourself according to the manual, because we do not want to risk them to fall off the piston during shipping.

When you order your FX Crown regulator you will receive:

  • Your regulator with the belleville springs, matching the pressure range you choose.
  • A set of spare valve disks
  • We will also include a “Huma-Air regulated” breech sticker
  • Fitting instruction as pdf download
