Polarstar Airsoft F2 HPA Engine with FCU (V2 / M4)
The Polarstar F2™ offers the same adjustments and performance as the Fusion Engine™ in a more compact cylinder version. Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for maximum control over loading time and air volume used. This also gives the user the ability to change the firing sequence giving which allows the engine to operate in both true closed bolt as well as "AEG" mode.
The F2™ has a spring loaded nozzle is spring biased forward which provides a consistent loading force and consistency regardless of operating pressure. Like the Fusion Engine™, both light and heavy spring options are available to adjust the loading force.
The included lightweight poppet valve in all F2™ Engines make the system even more air efficient. The design still operates on the same principle as the Fusion Engine™ poppet, but valve is able to operate at lower pressures while using less air volume to optimize efficiency.
The robust design of the F2™ allows for an operating pressure range of 45psi to 145psi which enables it to achieve both CQB and DMR velocities while employing only one nozzle for the entire velocity adjustment range, allowing the user to fit every role with one system.
