Shots Based on CO2 Cylinder Specifications
| Cylinder Size | Shots Per Fill | CO₂ Consumption per Shot (grams) | Typical Shot Range |
| 9 oz | 350–500 shots | 1.5–2 grams | 350–500 shots |
| 12 oz | 500–800 shots | 1.5–2 grams | 500–800 shots |
| 16 oz | 700–1,000 shots | 1.5–2 grams | 700–1,000 shots |
| 20 oz | 900–1,400 shots | 1.5–2 grams | 900–1,400 shots |
| 24 oz | 1,100–1,500 shots | 1.5–2 grams | 1,100–1,500 shots |
- CO₂ Consumption per Shot: Typically between 1.5 to 2 grams of CO₂ per shot, though this can vary.
- The actual shot count may fluctuate based on marker efficiency (gas usage), temperature, and shooting style.
- The table assumes normal shooting conditions (e.g., typical paintball game, moderate temperature).
Impact of Temperature on CO2 Paintball Tank Shot Count
| Temperature Range | CO₂ State | Impact | Expected Shot Count |
| 0°C (32°F) and below | CO₂ becomes more liquid, pressure drops | Lower internal pressure, fewer shots, potential inconsistency in shooting | Decreased by 10%-20% (e.g., 500 shots may drop to 400-640) |
| 10-21°C (50-70°F) | CO₂ is in a liquid/gas mix, stable pressure | Ideal temperature range for stable pressure and performance | Normal shot count (e.g., 500-800 shots) |
| 21-32°C (70-90°F) | CO₂ expands into gas, pressure slightly increases | Slight increase in shot count, but excessive heat may cause wear | Increased by 5%-10% (e.g., 500 shots may increase to 550-880) |
| 32°C (90°F) and above | CO₂ gas expands, pressure increases | Overheating can cause high pressure, risking safety and equipment damage | Risk of excessive pressure (more shots, but higher wear and safety risks) |
- Cold Temperatures (0°C and below): CO₂ tends to liquefy more, reducing tank pressure, leading to fewer shots and potential instability in shooting performance.
- Ideal Temperature Range (10-21°C): CO₂ is in a stable liquid/gas phase, providing optimal performance and normal shot count.
- Warmer Temperatures (21-32°C): CO₂ expands into gas, raising the internal pressure slightly. This may increase shot count, but be cautious about increased wear on the equipment.
- Hot Temperatures (32°C and above): Excessive heat causes CO₂ to expand too much, leading to high pressure and more shots. However, this can damage the gun and pose safety risks.
Pin Valve vs. On/Off Valve – Which Is Better?
Pin Valve or On/off Valve
A CO2 paintball pin valve is a simple valve that only allows gas to flow when pushed in, while an on/off valve provides a more controlled release of gas by allowing you to actively turn the flow on or off with a knob or lever, essentially acting as a “shutoff” mechanism for the CO2 supply.
Key points about the difference:
Function:
A pin valve only releases gas when pressed down, whereas an on/off valve can be fully open, fully closed, or somewhere in between depending on the knob position.
Control:
A pin valve offers minimal control over the gas flow, while an on/off valve gives the user precise control to adjust the gas output as needed.
Application:
A pin valve is typically used in situations where a quick burst of gas is needed, while an on/off valve is preferred when you need to precisely manage the gas flow over time.
| Working Pressure | 0-2200psi |

| Material | Brass |
Notes of Paintball CO2 Cylinders
Are the cylinders leak-tested and certified?
- 100% leakage detection is a must to ensure reliability during use.
What certifications do the cylinders meet?
- Cylinders should meet DOT, CE, or TPED standards to comply with global regulations.
What is the expected lifespan and re-certification schedule for the cylinders?
- Standard CO₂ tanks need re-certification every 5 years per DOT requirements.
How are the cylinders refilled, and what infrastructure is required?
- Many distributors consider the availability of refilling equipment such as dual-valve fill stations
Can the tanks be used interchangeably across various markers?
- Compatibility with standard fittings (CGA 320 threads) is critical.
- OEM Options:
Offer custom branding, colors, or logos for distributors targeting niche or premium markets.
- Packaging Solutions:
Ensure that packaging protects cylinders during shipping and storage, adding value for bulk orders.
- Certified Filling Stations:
Only refill at certified stations to ensure the cylinder is filled with the correct amount and type of CO₂.
- Avoid Overfilling:
Overfilling can cause excessive pressure, leading to potential safety hazards.
- Transport with Care:
Use protective caps on the valve during transport to prevent accidental opening or damage.
- Avoid Dropping:
Dropping the cylinder can weaken its structure and cause internal damage.
- Temperature Control:
Store cylinders in a cool, dry place. Avoid exposing them to direct sunlight or high temperatures, as CO₂ pressure increases with heat.
- Secure Upright Position:
Keep cylinders upright during storage to protect the valve and prevent potential leaks.
- User Training:
Ensure all users are trained on proper handling and maintenance procedures.
- Keep Records:
Maintain documentation of testing dates, certifications, and maintenance activities for compliance and traceability.
