For paintball players seeking a refillable compressed-air tank, the HK Army 48ci/3000psi models and Maddog 48ci/3000psi tank are practical full-size HPA options; the HK Army 13ci model suits compact setups. The Tippmann CO2 tank is an alternative for markers designed for CO2, but it is not a compressed-air tank. Compare capacity, regulator output, and air-source compatibility before choosing.
| Product | Best For | Key Detail |
|---|---|---|
| HK Army 48ci/3000psi, 850psi | Standard HPA use | Pressure gauge and two burst discs |
| Maddog 48ci/3000psi | Multiple compatible air systems | Preset 800psi output |
| HK Army 13ci/3000psi | Compact, lightweight setups | 800psi output |
| HK Army 48ci/3000psi, 850psi | Players comparing a second listing | Refillable HPA tank |
| Tippmann CO2 tank | CO2-powered markers | CO2, not HPA |
HK Army 48ci HPA Tank
This refillable aluminum tank holds 48 cubic inches of air at a 3,000psi fill pressure. Its regulator provides an 850psi output, and a pressure gauge lets users monitor the remaining air. Two safety burst discs and a fill-valve cover are also listed features.
Best for: Paintball players who want a standard-capacity HPA tank for compatible markers, or HPA-equipped airsoft guns. The listing describes it as compatible with standard paintball markers and as a CO2 alternative. It was selected for its useful combination of capacity, gauge, and regulator details.
Limitation: The tank ships empty and must be filled before use. Confirm that your marker accepts the regulator’s 850psi output.
Maddog 48ci HPA Tank
The Maddog is a 48ci aluminum cylinder with a 3,000psi fill pressure and a preset 800psi regulator output. The listing identifies it for paintball markers, airsoft HPA setups, airguns, and PCP rifles. It is also listed as DOT and TC certified.
Best for: Buyers who need a 48ci tank and whose equipment calls for an 800psi output. Its stated use across several types of compatible equipment makes it a flexible choice. Compare its output with your equipment requirements rather than assuming all HPA tanks are interchangeable.
Limitation: It ships empty, so arrange an appropriate air fill before use. The listing specifies a preset output, not an adjustable regulator.
HK Army Compact 13ci HPA Tank
This HK Army tank has a 13ci capacity and a 3,000psi fill pressure, with an 800psi regulator output and a pressure gauge. Its compact size is described as suitable for magfed and pump markers, low-impact .50-caliber paintball, and smaller players. The flat bottom supports upright storage.
Best for: Players who prioritize a compact, lightweight air system over the larger capacity of a 48ci tank. It was selected as the small-format option in this comparison.
Limitation: Its 13ci capacity is substantially smaller than the 48ci options. It also ships empty and must be filled before use.
HK Army 48ci Tank With Gauge
This listing describes a 48ci/3000psi aluminum HPA tank with an 850psi output, a pressure gauge, two safety burst discs, and a rubber cover for the fill valve. It is listed for standard paintball markers and HPA-equipped airsoft guns. These features make it comparable to the other HK Army 48ci tank in this guide.
Best for: Buyers comparing listings for a standard-capacity HK Army HPA tank. Check the listing details and selected option to confirm that the capacity and regulator specifications match your needs.
Limitation: The supplied product details match another 48ci HK Army listing, so they do not establish a meaningful performance difference between the two. It ships empty.
Tippmann Refillable CO2 Tank
This refillable aluminum tank is designed for most CO2-powered paintball markers, according to the product details. It is an alternative air source, not a compressed-air HPA tank. The listing also identifies it as ASTM certified.
Best for: Players whose marker is designed for CO2 and who specifically want a refillable CO2 cylinder. It is included to distinguish CO2 choices from the HPA tanks above.
Limitation: Do not treat it as an HPA tank. Check your marker’s approved air source before buying.
Buying Guide: How To Choose A Paintball Refill Tank
Should you choose HPA or CO2?
First check the marker manufacturer’s requirements. HPA tanks store compressed air and use a regulator to provide a specified output pressure. CO2 tanks hold carbon dioxide and are not interchangeable with HPA systems just because both attach to paintball equipment. Choose the air source your marker supports.
What tank capacity fits your setup?
The listed options include 13ci and 48ci tanks. A 13ci model is the compact choice for setups where smaller size matters. A 48ci tank offers a larger stated capacity. The product information does not establish an exact shot count, so do not assume capacity alone guarantees a specific number of shots.
How should you compare regulator output?
Compare the regulator output with your marker or air system’s requirements. The HK Army 13ci model lists 800psi, the Maddog lists 800psi, and the HK Army 48ci models list 850psi. A tank’s 3,000psi fill rating is not the same as its regulator output.
What does “ships empty” mean?
The HPA tanks in this guide ship without compressed air. You need access to a suitable fill source before use. Check that your local paintball field or other fill provider can service the tank and its specified pressure.
What safety and care details matter?
Use a tank only with compatible equipment and follow the manufacturer’s instructions. Check the gauge where provided, keep dirt away from the fill valve, and do not use a tank that appears damaged. The listed HK Army 48ci models include burst discs; the Maddog listing specifies DOT and TC certification.
Frequently Asked Questions
Can I use an HPA tank with any paintball marker?
No. Confirm that your marker accepts HPA and that the tank’s regulator output matches its requirements.
Do these compressed-air tanks arrive filled?
No. The listed HK Army and Maddog HPA tanks ship empty and need to be filled before use.
Is a 3,000psi tank output 3,000psi to the marker?
No. The 3,000psi figure is the tank’s stated fill pressure. The regulator output is separately listed as 800psi or 850psi on these products.
Is the Tippmann tank a compressed-air tank?
No. It is a refillable CO2 tank for compatible CO2-powered markers.
Is a 13ci tank or a 48ci tank better?
A 13ci tank is better for a compact setup; a 48ci tank provides greater stated capacity. Choose based on your equipment, fit, and air-use needs.
