Full description and what we offer
Ultraforce, owned by Kalen International Ltd., has been engineering airsoft gas systems and accessories since 1996. What started as a family operation in Hong Kong has grown into a world-leading independent supplier serving the Asia-Pacific Rim, Western Europe, and North America.
Ultraforce manufactures the complete range of airsoft propellant solutions:
GBB Gas Systems - Top Gas, Red Gas, Black Gas, Camo Gas (winter-rated) - Pressure ranges from 8kg to 18kg depending on ambient temperature - Each can delivers approximately 2,500 shots with 0.25mm BBs - Built-in lubricants safe for 32 types of plastic and rubber materials
CO2 Solutions - Cartridges and refillable systems - Certified 99.9% purity at 5.5 MPA - 12g cartridges with fill chargers - CO2-to-HPA adapters for platform flexibility
HPA/PCP Air Systems - Carbon fiber, aluminum, and steel tank options - Sizes from 13ci to 90ci capacity - Pressure ratings from 3000psi to 4500psi - Output: 160 to 1,660 paintballs per fill depending on tank size - Precision regulators, burst disks, fill stations, and gauges - High-output air compressors and scuba-compatible fill equipment
Accessories & Maintenance - Ultraforce Silicone spray lubricant (general-purpose gun parts) - Air regulators, hoses, adapters, and filters - BB speed loaders and tracers - Motors, chargers, batteries, and M4 magazines (250rds) - Tooling, targets, and IDPA/IPSC shooting cardboard - Target stands and metal targets
HPA (High Pressure Air) and PCP systems use compressed nitrogen or clean air instead of CO2. These gases expand faster, remain more consistent in cold weather, and eliminate the inconsistency CO2 brings to winter play. Standard $50 air compressors won't work—HPA tanks operate at 3000-4500psi and require high-output compressors or scuba tanks for refilling.
Built-in regulators feed 0-800psi to airsoft guns, with fixed regulators at 500psi for low-pressure platforms (250-450psi) or variable setups for higher-demand builds.
Ultraforce's pressure cylinders are precision-engineered to the highest specifications. Their HPA carbon fiber tanks combine lightweight construction with maximum pressure capability—ideal for extended field days. All products are Class 2.2 non-flammable certified and tested extensively.
Winter Operation: Switch to Camo Gas in cold weather. Different gas types provide different power levels. Camo Gas delivers 8kg at 20°C, while Black Gas reaches 18kg at the same temperature.
Airsoft gas canisters should never be left in vehicles. Temperature sensitivity is real:
