PolarStar Airsoft HPA Engine - Jack.
PolarStar Airsoft Jack HPA Electo Pneumatic System
The JACK™ was designed to answer the demand for an affordable, high performance HPA (High Pressure Air) conversion for AEG's. The system is a drop-in cylinder replacement that is universally compatible with a wide range of gearbox versions that have center-line nozzles.
Similar to its sister products, the JACK™ replaces the original gearbox components with a programmable pneumatic system allowing for higher performance and greater reliability over a gear driven system. Although economically priced, the JACK™ still retains the same performance and quality you have come to expect from PolarStar products.
The JACK™ has only one moving part, the nozzle, which acts as its own poppet valve. Similar to the Fusion Engine™ and F2™ poppet, the nozzle is only piloted by the solenoid to open air flow through the poppet with none of the firing air coming from the solenoid itself. This design lets the JACK™ send a higher flow of air down the barrel than systems that only use a solenoid as the firing valve.
Velocity: 500fps w/ .20g @ 130psi
The JACK™ allows for easy velocity adjustment 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 500fps 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 JACK™ 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
Although not a critical requirement during development, JACK™ does boast some highly respectable figures in this category. This is made possible by its intelligently laid out design which minimizes dead volume resulting in better air flow, faster response and less air used per shot.
PolarStar Jack Features:
- Assembled from CNC machined aluminum components with high performance delrin nozzle. Designed, manufactured and built in the U.S.A.
- Universal cylinder design is compatible with numerous gearbox versions
- Optimized flow profile, firing point and flow path promotes superior shot consistency and accuracy
- Capable of functioning in damp and sub-freezing climates without affecting performance or reliability
- User selectable Semi/Full Auto, Semi Auto Only and Variable Burst modes
- Independently adjustable velocity and cyclic rate. Instantaneous trigger response. Faster than an AEG with a Li-po
- Auto Switch mode allows for proper selector configuration for specific models
- Easy to use Fire Control Unit (FCU) with LCD display and five position joystick
**All kits come with an FCU, Switchboard, Wire Harness and any additional components needed to convert the specific airsoft rifle model for which the kit is configured. The HPA Tank, Air Rig (regulator/line/QD fitting) and Battery needed to operate the system are purchased separately.
