X Plenum .22 | 40mm | For Hatsan models | Huma-Air

X Plenum .22 40mm – component for your PCP air rifle setup

This plenum from Huma-Air is a specific upgrade component for Hatsan PCP air rifles produced after 2018. With the 40mm of additional air capacity between the regulator and the valve, this accessory ensures a more consistent air supply with every shot. The result: improved shot power and more consistent velocities over multiple shots.

Technology and application

A plenum functions as an air buffer in your PCP system. This component is mounted between the regulator and the valve block of your Hatsan air rifle. The .22 caliber designation indicates that this plenum is optimised for .22 (5.5mm) configurations. Thanks to the extra air volume, the regulator has more time to recover between shots, which delivers noticeably better performance, especially during rapid-fire sequences.

Ease of use and integration

This plenum fits Hatsan models such as the Flash, AT44, Bullboss, Trophy Flashpup, BT65, Galatian and Gladius – provided they were produced after 2018. Installation requires disassembly of your air rifle up to the valve block. Huma-Air is known for the precision fit of their components, ensuring this accessory integrates seamlessly with the original Hatsan parts.

Who is this component intended for?

PCP shooters looking to optimise their Hatsan air rifle for competition, benchrest shooting or Field Target will find this plenum a valuable upgrade. Hunters who require consistent performance for follow-up shots also benefit from the more stable air supply. Technically skilled users who enjoy customising their setup will appreciate the noticeable performance improvement.
