Maddog Aluminum HPA Paintball Tank – 13ci / 26ci / 48ci 3000 PSI Compressed Air System

Maddog Refillable Compressed Air HPA Paintball Tanks – 13ci / 26ci / 48ci 3000 PSI Compressed Air System

Reliable compressed air performance built for real paintball gameplay. The Maddog Aluminum HPA Paintball Tank is a refillable 3000 PSI compressed air system available in 13ci, 26ci, and 48ci size options to match everything from compact magfed builds to full recreational paintball setups.

Designed for dependable performance, consistent pressure, and all-weather reliability, Maddog HPA tanks are an excellent upgrade over traditional CO2 systems. Whether you call it an HPA tank, compressed air system, or 48/3000 tank, the result is the same: smoother gameplay, more consistent velocity, and improved marker performance. 

Consistent Air Output • Durable Aluminum Construction • Built for Paintball

Built for ALL Your HPA Toys!

Every Maddog HPA tank is built for reliable field performance with player-focused designs emphasizing consistency, safety, and durability. Maddog aluminum compressed air systems are designed to provide reliable HPA performance at an affordable price point. Each tank includes a durable aluminum bottle, integrated regulator, fill gauge, and standard output pressure compatible with most paintball markers. 

Choose Your Tank Size

• 13ci / 3000 PSI – Ultra-compact setup for magfed markers, pistols, pump markers, and lightweight tactical builds
• 26ci / 3000 PSI – Compact middle-ground option for magfed and scenario players wanting more air without moving to a full-size tank
• 48ci / 3000 PSI – Best all-around choice for beginner, recreational, and standard paintball marker setups

Quick Recommendation: If this is your first HPA tank, start with the 48ci / 3000 PSI. Choose the 13ci or 26ci if you specifically want a smaller, lighter, or more compact setup.

Tank sizing and weight comparison based on manufacturer reference guides and product specifications. 

Key Features

• Durable Aluminum Bottle – Built for rugged field use and long-term reliability
• 3000 PSI Fill Rating – Standard aluminum compressed air pressure rating
• Approx. 800–850 PSI Output – Compatible with most paintball markers using HPA
• Integrated Fill Level Gauge – Monitor remaining air pressure during gameplay
• Preset Regulator System – Stable and reliable air output
• DOT / TC Certified – Built to meet industry safety standards
• Flat Bottom Design – Stores upright in staging areas and gear setups
• 5-Year Hydro Cycle – Fresh hydro dates for safe field use

Estimated Shots Per Fill

Actual shot count depends on your marker efficiency, firing mode, temperature, regulator settings, and fill quality, but here are general estimates for most paintball setups:

• 13ci / 3000 PSI – Approx. 180–300 shots
  Compact capacity ideal for pistols, pump markers, magfed, and lightweight tactical builds
• 26ci / 3000 PSI – Approx. 350–550 shots
  Balanced compact setup with more usable air capacity for scenario and magfed play
• 48ci / 3000 PSI – Approx. 600–900 shots
  The most practical all-around option for recreational and beginner paintball setups

Pro Tip: If this is your first HPA tank and you are not specifically building a compact magfed or pistol setup, the 48ci / 3000 PSI is usually the best starting point.

Shot count estimates will vary depending on marker type, weather conditions, firing mode, regulator tuning, and air fill quality.

Why Upgrade from CO2 to HPA?

Compressed air systems (HPA) provide more consistent performance than CO2 because they maintain stable pressure across varying temperatures and firing speeds. 

• More consistent velocity
• Improved accuracy and shot consistency
• Better cold-weather performance
• Reduced pressure spikes during rapid fire
• Recommended or required for many electronic paintball markers

Important Tank Shipping Notice

ALL paintball tanks ship EMPTY to comply with Department of Transportation safety regulations and must be filled prior to use.

Paintball HPA tanks require high-pressure compressed air fill equipment rated for 3000 PSI systems. Standard home or shop air compressors cannot properly fill paintball HPA tanks.

How to Read Your Tank Hydro Date

Every paintball HPA tank includes a stamped manufacture or hydrostatic test date on the tank bottle. This date is commonly called the “hydro date.”

• Example: 03 ◇ 25 = Manufactured or tested in March 2025
• Aluminum HPA tanks typically require hydro testing every 5 years
• The stamped date is NOT the expiration date

Tanks that are out of hydro may not be filled by paintball fields or fill stations until they are re-tested.

Fresh hydro dates are guaranteed on all new Maddog HPA tanks. Expect tank dates within up to 1 year of their manufactured date.

Need to Carry Your Tank on Your Back?

Pair your HPA tank with a remote coil line and tank-carry harness to improve balance and reduce front-heavy marker feel during longer games.

• Moves tank weight off your marker
• Improves comfort during scenario and woodsball play
• Works great with 4+1 and 6+1 harness systems

Frequently Asked Questions

Do Maddog HPA tanks ship filled?

No. All compressed air paintball tanks ship empty and must be filled before use. 

Which tank size should I choose?

Choose 48ci for most beginner and recreational setups. Choose 26ci for compact tactical setups. Choose 13ci for ultra-light magfed, pump, or pistol builds.

Can I fill this with a regular air compressor?

No. Paintball HPA tanks require specialized high-pressure compressed air fill equipment. Standard home compressors cannot safely fill a 3000 PSI paintball tank. 

What does the hydro date mean?

The hydro date is the manufacture or hydrostatic testing date stamped on the tank. Aluminum tanks typically require re-testing every 5 years.

Will this work with my paintball gun?

These tanks use standard paintball ASA threading and are compatible with most paintball markers designed for compressed air systems.
