What’s A Plenum?

The plenum in an airgun is the chamber of compressed air located between the regulator and the valve.

The regulated air it contains is released when the trigger is pulled. The air then rushes through the valve opening and propels the pellet or slug down the barrel.

The combination of pressure and volume of air released is a the key factor in achieving power in a PCP air rifle. Generally-speaking, the larger the plenum, the more power can be generated by the airgun. Hence the larger FX Power Plenum.

FX Airguns has spent the last two years designing and experimenting with different solutions to add this needed volume allowing the Impact to shoot different and heavier projectiles. This has been achieved while also successfully maintaining the Impacts ability to shoot pellets at lower velocities.

Other Modifications:

In addition to adding a larger plenum, a significant amount of parts inside the Impact were also changed. This was to ensure that the internal working mechanisms could not only handle the demands shooters would place on it, but to make sure the Impact would still shoot standard weight pellets.

In addition, the fine tuning options the FX Impact has always offered have been kept in place. This was also done making sure these many changes and parts could be applied to existing Impacts that are owned by customers already.

FX Impact MKII with Power Plenum Benefits:

1. Higher velocities can be obtained. For instance, the standard .22 caliber FX Impact previously achieved 32 Ft/Lbss. of muzzle energy with standard pellets. With the FX Power Plenum added to the .22 caliber Impact, though tuned from the factory to still shoot at 32 Ft/Lbs, you can now adjust the gun and shoot heavier slugs and obtain as high as 60 Ft/Lbs of Muzzle Energy.

2. Lower velocities still available. While the higher powers are now achievable, often shooters want lower power to for different shooting situations (or to simply extend shot count). Thanks to the internal part changes to the Impact, the lower velocities can still be achieved.

3. Increased shot count per fill. With the FX Power Plenum, the 75 shots per fill that the standard tuned .25 caliber Impact previously achieved, is now increased to 110 shots per fill. That’s just one example.

4. Lower regulator pressure required. You get the same velocity result with lower regulator pressure due to the FX Power Plenum. Lower pressure will also result in less wear and tear maintenance to your rifle, says FX Airguns.

The FX Impact MKII with Power Plenum is currently shipping to FX dealers around the world. The company says that US-based FX Dealers should have their first shipment of Impacts with the Power Plenum by the second week of January.

.35 Caliber FX Impact Update:

For those anxiously awaiting the .35 caliber FX Impact will be pleased to know that with the addition of the FX Power Plenum, the Impact is now fully ready for this exciting hunting caliber.

The .35 caliber Impact is in its final stages of testing and will soon go into production. Full details to follow, but the .35 caliber Impact will be a 150+Ft/Lbs hunting rifle!
