PolarStar F2 HPA Conversion Kit
F2 is essentially a Mini Fusion Engine. It offers the same adjustability and performance as the Fusion Engine in a cylinder-sized package.
Patented Dual Solenoid Design
The dual solenoid design of the F2 provides the same functionality as the legendary Fusion Engine„¢ but in a more compact, efficient, and flexible design. Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for unparalleled control over both the loading time and air volume used. Additionally, this makes it possible to change the firing sequence giving it the ability to operate in both true closed bolt as well as "AEG" mode.
The F2 incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine poppet. This valve is able to operate at lower pressures and uses less air volume to function which optimizes air efficiency.
The standard F2 poppet is equivalent to the Red Low-Flow poppet of the Fusion Engine.
Spring Loaded Nozzle
The F2 nozzle is spring-biased forward which provides a consistent loading force regardless of operating pressure. It shares the same spring as the Fusion Engine with both light and heavy spring options available to adjust the loading force.
The robust design of the F2 allows for an operating pressure range of 45psi to 145 psi which enables it to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.
- Velocity Range: 250fps - 500fps
