The Air Venturi Nova Side Fit Power Plenum V2 does more than just increase your air rifles power and performance! With the standard plenum and block, this 15cc additional power plenum will total the plenum size at 28cc. But you get more than just larger plenum capacity.

This new V2 design is by far the easiest power plenum to install. Unlike other versions, you don’t install this part below the rifle stock, or in line with your air reservoir. You fit it on the side, in place of your regulator gauge, and then place your regulator gauge on the plenum itself. So, apart from gaining power and performance, your regulator gauge is now set at an angle. Therefore, you can see the regulator pressure at a glance, in stead of having to turn your rifle or head.

With a plenum installed, your air rifle can operate at lower regulator pressure and be more efficient, without sacrificing power. A plenum is the chamber of compressed air located between the rifle’s regulator and the valve. When you pull the trigger, the regulated air it contains is released.  This air then rushes through the valve opening and propels the projectile (pellet or slug) down the barrel.

Designed and manufactured right here in South Africa, and precision CNC machined from high grade aluminium, ensuring durability, as well as minimum added weight.

Made in South Africa for Air Venturi and Nova PCP airguns.



Surprisingly, not everyone knows that Nova Vista produces the Avenger and Avenge-X models for Air Venturi. You get slight changes (apart from branding) on some of the models, like carbon bottles in stead of aluminium bottles. However, they are essentially the same air rifles. You can, therefore, install this part in both the Air Venturi and Nova Vista air rifles.


We installed and tested this power plenum on the following regulated air rifle models:

Air Venturi Avenger Synthetic
Nova Vista Leviathan PS-R2 Synthetic / Camo
Air Venturi Avenge-X Tactical Tube / Bottle


Because Nova Vista / Air Venturi gave these rifles the same bases, you could, in theory, install this power plenum on any model. However, we have not tested installation on every model yet. So there may be a chance that the rifle stock simply would not allow flush fitment. In this case, you will have to modify the rifle stock.

Also, make sure you refer to your specific rifle’s owner manual before attempting installation. Your regulator gauge may be located either on the left or right hand side, depending on your air rifle’s model.

We can’t guarantee that the plenum will be the exact same colour as the rifle’s tube and barrel. Because there are variations in colour from batch to batch in these airguns, the colour may be slightly different.



Please Note:

Any unauthorised alterations or modifications may affect any warranty or guarantee held by either the manufacturer, importer or reseller, where applicable. We highly recommend these be done by an authorised and / or accredited air rifle service centre or air smith.

Installation of these products are done at own risk.
