Like the Fusion Engine™ and JACK™, the patent pending F1™ is a high performance HPA (High Pressure Air) system which replaces the traditional piston and gears of an AEG with a programmable pneumatic system.
The F1™ uses a custom solenoid designed by PolarStar and manufactured by MAC Valves. The design allows the solenoid to become an integral part of the system and not simply a a switch to control gas flow. This not only makes the F1™ more compact but also minimizes the dead volume inside of the system, increasing efficiency and decreasing response time.
