Extreme Performance 12 Expansion Chamber For CO2 Atomizer And HPA Volumizer

Extreme Performance 12-Chamber Expansion Chamber / HPA Volumizer features a modular two-piece design consisting of a 12-chamber expansion ring and an adapter main body. Small and compact, it adds less than 1.5 in / 36 mm to the overall length. Precision-machined from 6061 aircraft-grade aluminum, it weighs only 2 oz, delivering maximum performance.

CO₂ Configuration:
When used with CO₂, the expansion ring is installed. CO₂ is stored as a liquid under pressure, and when the valve opens, liquid CO₂ can rush directly toward the launcher’s valve. The 12 internal chambers provide additional space and dwell time for the CO₂ to expand from liquid into gas before reaching the valve. This stabilizes pressure, reduces cold shock, and minimizes velocity drop, valve freeze, and O-ring damage, helping maximize usable CO₂ pressure for consistent, peak performance.
Features:
- Uses the 12-chamber expansion ring
- Allows liquid CO₂ to expand into gas before reaching the valve
- Stabilizes pressure and reduces cold shock
- Minimizes velocity drop, valve freeze, and O-ring damage
- Maximizes usable CO₂ pressure for peak launcher performance

HPA Configuration:
When used with HPA, the expansion ring is removed and the unit functions as an HPA volumizer. The adapter main body provides additional air volume, allowing compressed air to be temporarily stored during each firing cycle. This prevents pressure depletion between shots, maintains consistent air delivery, and ensures maximum power and reliable performance from the launcher.
Features:
- Expansion ring removed to function as an HPA volumizer
- Stores additional air volume during each firing cycle
- Prevents pressure depletion between shots
- Maintains consistent output and peak power performance

Compatible with a wide range of platforms, including paintball markers, airsoft guns, BB guns, pellet guns, and defense launchers.
