PolarStar F1 - V3 AK
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 unique flow control system uses an integral check valve to regulate the forward speed of the nozzle while maintaining the fastest retract speed possible. This system is also what makes the F1's "2-stage" firing possible. When the nozzle is traveling in the forward direction the check valve is sealed, limiting the speed of the nozzle for greater consistency. When the nozzle reaches the forward position the check valve opens to allow the maximum flow into the barrel. The additional flow is maintained throughout the rearward travel of the nozzle, allowing it to retract without limiting the speed.
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.
The F1 is compatible with virtually every AEG gearbox, including those with offset nozzles by using either a centerline or offset front cylinder. The front cylinders are interchangable and a centerline F1 may be converted to an offset F1 by simply swapping the front cylinder and nozzle.
PolarStar single-solenoid systems (JACK and F1) use the same electronics, making the F1 compatible with any kit already available for JACK. Some of the switchboards that are already available or coming soon include:
Elite Force HK417
Elite Force Tavor (S&T)
Plugboards for machine guns or custom installs
