Paintball Compressed Air Tanks by Size | HPA Tanks

Paintball compressed air tanks, also known as HPA or high pressure air, is the most widely used propellant in paintball today. It delivers consistent pressure, works with all modern paintball markers, and is supported at nearly every paintball field. For most players, compressed air is the safest and most reliable option.

If your paintball marker uses a standard ASA, meaning the tank screws directly into the marker, it is designed to run compressed air. Unlike CO2, compressed air is not affected by temperature or rapid firing, making it ideal for mechanical, electronic, and tournament level markers.

Compressed air tanks are available in a wide range of sizes and materials. Choosing the right tank depends on comfort, weight, and how much air you need during play.

13ci to 48ci Aluminum Compressed Air Tanks

Small aluminum compressed air tanks ranging from 13ci to 48ci are commonly used for entry level setups, paintball pistols, mag fed markers, and younger players. These tanks are affordable, durable, and easy to handle.

Because aluminum tanks operate at lower pressures than carbon fiber tanks, they typically offer fewer shots per fill. However, they are a practical option for casual play, backyard use, and situations where simplicity and cost matter most.

13ci tanks are often used for pistols and compact markers, while 48ci aluminum tanks provide a lightweight option for smaller players or minimal setups.

45ci Compressed Air Tanks

45ci tanks are commonly used for compact and lightweight setups. They are popular with pump players, mechanical markers, and anyone who prefers a minimal and agile feel while still having enough air for multiple games.

This size is also a good option for younger players who want more capacity than a small aluminum tank without jumping to a full size setup.

48ci and 50ci Compressed Air Tanks

48ci and 50ci tanks are often referred to as peanut tanks due to their short and compact shape. These tanks are lightweight and easy to handle, making them a common choice for kids and smaller framed players.

Some players enjoy the tight profile these tanks create, while others find the shorter length less ergonomic. Comfort can vary depending on marker setup and personal preference.

68ci Compressed Air Tanks

68ci paintball tanks are the most commonly used size in paintball. They offer an excellent balance of size, weight, and air capacity, making them suitable for recreational play, tournament use, and everything in between.

Modern 68ci tanks are slightly shorter and wider than older versions, so returning players may notice a difference compared to tanks from previous years.

77ci Compressed Air Tanks

77ci compressed air tanks are a popular choice for players who want more air capacity than a standard 68ci tank without moving into oversized setups. These tanks are similar in length to older style 68ci tanks but offer increased total air volume.

77ci tanks are commonly used by experienced players and back players who want additional shots per fill while maintaining a balanced and comfortable setup.

80ci and Larger Compressed Air Tanks

80ci compressed air tanks and larger sizes are designed for players who prioritize maximum air capacity. These tanks are often chosen by tournament back players, high volume shooters, and players participating in big games or long scenario events.

In addition to 80ci options, larger tanks such as 88ci, 90ci, and 100ci plus sizes are available for specialized setups where minimizing refills is a priority. Because of their size and weight, these tanks are best suited for specific play styles rather than everyday recreational use.

Choosing the Right HPA Tank Size

Tank size choice depends on comfort, marker efficiency, playing style, and personal preference. While air capacity is important, balance and ergonomics often matter just as much during a full day of play.

If you are unsure which size is right for you, 68ci compressed air tanks remain the most versatile and widely recommended option.

Compressed Air Tank Size Frequently Asked Questions

Can all paintball markers use compressed air?

Yes. Nearly all modern paintball markers are designed to run compressed air. If your marker has a standard ASA where the tank screws in, it is compatible with compressed air.

What is the difference between aluminum and carbon fiber air tanks?

Aluminum tanks are more affordable and durable but hold less air and operate at lower pressures. Carbon fiber tanks are lighter, hold more air at higher pressures, and are preferred by most regular and competitive players.

What size compressed air tank is best for beginners?

For most beginners, a 68ci tank is the easiest and most versatile option. Younger players or smaller setups may prefer 48ci or aluminum tanks for reduced weight.

Are smaller tanks like 13ci and 48ci enough for a full day of play?

Smaller tanks can work for casual play, pistols, or mechanical markers, but they will require more frequent refills. Larger tanks provide more flexibility for longer sessions.

Why do some players choose 77ci or 80ci tanks?

These sizes offer increased air capacity, with 77ci focusing on balance and comfort and 80ci and larger prioritizing maximum air for high volume play.

Does tank size affect how many shots I get?

Yes, but shot count also depends on marker efficiency, weather, paint quality, and regulator performance. Tank size alone does not guarantee a specific number of shots.
