The Details:

  • Designed from the ground up as a high-performance mechanical HPA system, not a modification of a solenoid operated design.
  • The patent-pending valve mechanism provides excellent efficiency and consistent velocity combined with a realistic trigger pull and reset.
  • Completes a full shot cycle on the trigger pull alone which translates into consistent nozzle movement and rapid follow-up shots.
  • Adjustable trigger. Adjustments include Weight, length of pull, and over travel.
  • Adjustable nozzle dwell/return speed.
  • Wide operating pressure range of 60 to 180psi.

 

The Kythera has been the most eagerly anticipated product from PolarStar in the past decade. This HPA system is a radical departure from all previous systems that PolarStar has produced since the Kythera does not use a battery, an FCU, or any type of electronics. The Kythera is completely mechanical. This means you never have to worry about charging batteries or work with delicate electronics. It also means that the system is completely waterproof.


The name "Kythera" (ky-the-ra) was derived from the Antikythera Mechanism which is a mysterious device that was discovered by sponge divers off the coast of the Greek island Antikythera. The mechanism was so advanced in design that scientists have been studying it for decades to discover its purpose. The machine dates from around the end of the 2nd century B.C. and is the most sophisticated mechanism known from the ancient world. Nothing as complex is known for the next thousand years. The Antikythera Mechanism is now understood to be dedicated to astronomical phenomena and operates as a complex mechanical "computer" that tracks the cycles of the Solar System.

For this reason, we used the name Kythera for the valve mechanism at the core of a new line of PolarStar mechanical HPA systems. Although it contains very few parts and is easy to install and maintain, the system incorporates a very intelligent design and is unlike anything else on the market. The system was designed as a mechanical system from the ground up and uses a realistic trigger mechanism that can be applied to single-shot, semi-automatic, and fully automatic systems.


The first of these systems is Kythera SA (Semi-Automatic), the semi-auto-only variant for use in AEG gearboxes.
