1.Air Venturi Wingman PCP Refill Tanks

 

 

 

The Air Venturi Wingman PCP Refill Tanks are premium, high-pressure carbon fiber cylinders designed specifically to keep your pre-charged pneumatic (PCP) airguns topped off and ready for action. Whether you’re pest hunting, plinking at the range, or competing in precision shooting, these tanks deliver unmatched portability, power, and practicality.

Constructed with carbon fiber filament wound over an aluminum bladder, the Wingman tanks offer a lightweight yet rugged solution for mobile or home airgun charging. Unlike bulky steel scuba tanks, the Wingman series weighs considerably less while offering a maximum pressure of 4,500 psi (310 bar) — more than enough to handle most modern PCP rifles and pistols.

Available in 74 cu. ft. (Wingman 74) and 98 cu. ft. (Wingman 98) sizes, each tank supports dozens of refills before needing a recharge, making them ideal for field days or competition use. For instance, the Wingman 74 can offer 30+ partial fills or over 15 full fills on a 3,000 psi gun with a 215cc reservoir.

Each Air Venturi Wingman tank comes fully equipped and ready for airgun use. The included charging station features:

Factors to Consider when Choosing Best Carbon Fiber Cylinder Tanks for Air Rifles

1. Tank Capacity (Volume)

The capacity of a carbon fiber air tank, typically measured in liters (L) or cubic inches (ci), determines how many refills you can get for your PCP air rifle before needing to recharge the tank. For field use or occasional shooting, a smaller tank like 4.5L may suffice, offering lightweight convenience. However, for extended range sessions or multiple rifles, a larger tank such as 6.8L or 9L will provide significantly more fills, reducing the need for frequent refills and offering better long-term convenience.

2. Working Pressure Rating

The working pressure, commonly 300 BAR (4500 PSI), is crucial because it defines how much air the tank can safely store. Higher pressure ratings allow for more air storage in the same volume, giving more refills per fill cycle. Always ensure your air rifle and filling equipment are compatible with the tank’s pressure. A high working pressure tank also means a longer usage period between refills, which is especially useful for competitive shooters or hunters who spend long hours in the field.

3. Material and Build Quality

Carbon fiber tanks use a composite construction that typically includes an aluminum liner wrapped in carbon fiber and often glass fiber for added durability. The quality of these materials significantly affects the tank’s safety, longevity, and weight. Tanks made with high-grade carbon fiber and AL6061 aluminum alloy liners, like those from Acecare or Tuxing, offer superior impact resistance, corrosion protection, and reliable pressure retention. A well-constructed tank ensures both performance and safety during high-pressure use.

4. Weight and Portability

Weight is a key consideration, especially for field use. One of the biggest advantages of carbon fiber over traditional steel tanks is weight reduction—carbon fiber tanks can be up to 70% lighter. A tank weighing under 5 kg (11 lbs) is ideal for mobile use, fitting easily in a backpack or range bag. Lightweight tanks are essential for hunters or shooters who frequently move between locations and need gear that won’t slow them down.

5. Certification and Safety Standards

Always check whether the tank is CE, EN12245, or DOT certified. These certifications ensure the tank has passed rigorous safety and performance tests. European CE-certified tanks are suitable for most users globally, while DOT certification is essential if you plan to transport your tank across state lines or in vehicles in the United States. Choosing a certified tank means you’re investing in a product that meets international safety standards, reducing risk during use and filling.

6. Valve and Thread Compatibility

The thread size and valve type (typically M18x1.5) should be compatible with your fill system and air rifle. Some tanks include a built-in valve, bleed valve, and gauge, while others require separate purchases. Compatibility with DIN or SCBA valve fittings is also important depending on your fill source (compressor or scuba tank). Make sure the tank setup matches your existing gear to avoid needing additional adapters or risking an improper fit that could lead to leaks or unsafe fills.

7. Retest Interval and Service Life

Most high-quality carbon fiber tanks have a design service life of 15 years, with a retest interval of 3 to 5 years depending on the certification and local regulations. This means the tank must be pressure-tested periodically to ensure continued safety. A longer retest interval saves maintenance time and cost, while a long service life ensures a good return on investment. Always check these timelines before purchasing to avoid unexpected compliance issues later.

8. Intended Use and Versatility

While your primary use may be for PCP air rifles, many tanks are designed for multiple applications like paintball, scuba diving, emergency breathing systems (SCBA/EEBD), or industrial use. Choosing a versatile tank expands its value, especially if you participate in other air-driven hobbies. Versatile tanks are also more likely to have widespread compatibility with different hoses, valves, and regulators, giving you more flexibility across different gear and environments

Frequent Asked Question Best Carbon Fiber Cylinder Tanks for Air Rifles

1. What size carbon fiber tank should I get for my PCP air rifle?

The ideal size of your carbon fiber tank depends on how often you shoot and whether you’re using it in the field or at a fixed location like a range. Smaller tanks (like 4.5L or 90ci) are lightweight and more portable—perfect for carrying in a backpack during a day of hunting. Larger tanks (6.8L or 9L) offer more air capacity, allowing you to refill your PCP rifle multiple times without needing to recharge the tank itself, which is ideal for benchrest shooting or extended range sessions. If you’re unsure, a 6.8L tank offers a great balance between capacity and portability for most airgunners.

2. Are carbon fiber tanks safe to use at 4500 PSI?

Yes, carbon fiber tanks that are properly manufactured and certified (e.g., CE, EN12245, DOT) are specifically designed to handle high pressures—typically up to 4500 PSI (300 BAR). They are constructed with a high-strength aluminum liner wrapped in carbon fiber and glass fiber for maximum durability and burst resistance. These tanks undergo rigorous testing, including hydrostatic pressure tests of up to 7500 PSI or more. As long as the tank is used within its specified pressure limits, periodically retested, and maintained properly, it is very safe to use at 4500 PSI.

3. Can I use the same carbon fiber tank for other applications like paintball or scuba?

Yes, many high-quality carbon fiber tanks are versatile and can be used for multiple applications, such as paintball,SCUBA diving, emergency breathing systems (SCBA/EEBD), and industrial air tools—as long as the valve fittings and certifications meet the requirements for those uses. For instance, a CE-certified tank with an M18x1.5 thread and high-pressure rating can work across several air-based systems. However, it’s essential to verify the certification requirements in your country and the compatibility with the specific regulators or fill systems used in other activities. Some applications, like scuba, may require DOT certification in the U.S. or different valve types.

Conclusion

In conclusion, selecting the best carbon fiber cylinder tank for air rifles involves balancing performance, safety, and portability to match your specific shooting needs. High-quality tanks offer lightweight construction, high-pressure capacity, and long service life—making them ideal for both field use and extended range sessions. By considering key factors such as capacity, working pressure, material quality, certifications, and intended applications, you can invest in a tank that delivers reliable air supply, enhances your overall shooting efficiency, and ensures safe, long-term use. A well-chosen carbon fiber tank is not just a convenience—it’s a critical component in maximizing the performance of your PCP air rifle setup
