300 Bar | PowAir ULTIMATE SERIES 1.3L / 77ci Ultralite HP System with MAXREG Regulator

Maximum Capacity and Ultralight Design for Long Operations

The PowAir ULTIMATE SERIES 1.3L Ultralite is designed for players who require a maximum air supply without compromising on weight. This system, with a working pressure of 300 Bar (4500 PSI), utilizes state-of-the-art composite materials, resulting in a tank weight of only 780 g. The larger 77ci (1.3L) volume provides a significantly longer runtime per fill, which is crucial during long game scenarios where frequent air refills for your gun are not possible.

Included in the set is the precise PowAir MAXREG regulator with full European PI certification. This regulator is highly flexible, allowing the user to adjust the output pressure from the standard 850 PSI to a low-pressure mode of 450 PSI. As a result, this HP system is fully compatible with all modern guns on the market, ensuring a stable and consistent air supply for accurate shooting.

Safety is the top priority for the ULTIMATE SERIES, as confirmed by ISO and PI-TÜV certifications. The composite construction is extremely resistant to impacts and mechanical damage that can occur during intense movement with a gun in the field. The system has a specified lifespan of 15 years with mandatory inspections every 5 years, making it a reliable long-term investment for your gear.

Frequently Asked Questions (FAQ):

What is the difference in shot count between the 1.1L and 1.3L tanks?
The 1.3L version offers approximately 15–20% more air, allowing you to stay in action longer without having to head to the fill station with your gun.

Is this system suitable for Air-Stock stocks?
Due to the 11 cm diameter, this tank is intended more for carrying in a pouch on your back (via a remote line) or for guns with large stock space.

How do I change the output pressure on the regulator?
The pressure change is performed using the internal shim system in the regulator. We recommend doing this only when the tank is completely empty and disconnected from the gun.
