The R&D team of JNS has more than 10-year-experience in the design and evolution of the performance of protein skimmers. This time, we launch a high-performance buffer chamber: ConeS system
Each buffer cone of the ConeS system is a perfect curve which improves the mixing efficiency of the air and water flow inside the buffer chamber and eliminates the turbulent flow caused by the injection from the motor.
It provides a stable laminar flow inside the protein skimmer and enhances highly the performance of the protein skimmer.

Now ConeS RC series protein skimmer is released with a whole new design ConeS system.

The RC Series features an exclusive design, bubble recirculation that dramatically reduces bubble spillage.
It makes free bubbles recycle and increases the contact time between bubbles and water. This revolutionary design with ConeS boosts the performance. Definitely, it is a perfect technological design.

  RC series has achieved great results in improving the flow of air and water, made free bubble recycle. The flow is evenly and gently discharged through the flow plate at the bottom of the main body.


  The collection cup of the RC series is also well-designed, ergonomic, comfortable, and easy to clean.

Proprietary JNS needle wheel impellers, it will show you a brilliant performance.

 Quick-Precise adjustment valve allows fast precision tuning of the skimmer water level to control wet/dry foam production

The new silencer for the double expansion chamber reduces much the noise of airflow. It gives you a quiet environment.
