The F1 is a high performance, universal HPA (High Pressure Air) drop-in cylinder designed to fit virtually any AEG gearbox. It is available as both a Centerline version, which will work with most common gearbox types, but it is also available in an Offset version to work with those unique gearboxes such the V6 and V7. It replaces the original gearbox components with a programmable pneumatic system allowing for higher performance, greater reliability and complete adjustability. This allows the F1 to fill any role ranging from CQB to sniper with no additional components needed.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.Despite its sophisticated design, the F1 only has 5 parts which translates into extreme reliability and makes maintaining the F1 very easy. To further simplify maintenance, the F1 requires no tools for disassembly
JACK/F1 Standalone Mini FCU
New voltage regulators allow for extremely low power consumption in sleep mode. Drawing under 28uA while idle, the Mini FCU is over 300 times more efficient than the original Standard FCU and can operate in sleep mode for close to one year on a small 250mAh pack.
Elimination of the solenoid MOSFET, joystick and LCD, along with careful selection of the remaining components allowed the size of the Mini FCU to be reduced significantly compared to other FCUs. It's small size allows the Mini FCU to fit inside the gearbox shell keeping the control unit and wire harness protected from damage.
Despite it's size, the Mini FCU actually expands on the functionality of the Standard FCU by adding an integral Motor Control Unit and support for 4-position selectors. In order to make setup as easy as possible the MCU output port can be used with either a box mag or optional speaker to provide feedback during programming.
