PolarStar Airsoft F1 HPA Electro-Pneumatic System with Full Size FCU (Model: VFC HK417)

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 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.

Unlike similar systems, the F1 incorporates a dual purpose flow control system which allows for nozzle speed regulation and two stage firing through an integral check valve. The check valve system regulates nozzle speed based on the direction of movement while also controlling flow to the secondary firing point. This unique design promotes both increased cyclic rate and smoother chambering.
