Polarstar F2 - HPA Conversion Kit
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.
A robust design allows for an operating pressure range of 45psi to 145psi which enables the F2™ to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.
Additionally, its 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 F2™ allows for easy velocity adjustment just by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 480fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum velocity while shorter barrels will decrease it. |
| ROF: 30rps |
| The maximum cyclic rate of the F2™ is affected by several factors such as the operating pressure as well as quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations. |
| Air Efficiency: 1000+ shots from 13/3000 @ 1.5J w/ .28g |
| The standard F2™ poppet valve is equivalent to the Red Low-Flow poppet of the Fusion Engine™. However, this valve responds faster and requires less air volume to operate so the F2™ is able to achieve greater air efficiency than even a finely tuned Fusion Engine™. |
