Skimz Leopard’s Integrated Inverted Cone (IIC) channel bubbles to the outer side of the chamber to achieve optimal skimming performance. This significantly reduces surface agitation, thus creating superb foaming within the skimmer and results in increased skimming efficiency. Together with the use of the bubble plate design, turbulence within the chamber is significantly reduced, allowing maximum air flow capacity in a compact skimmer. Skimz VSC (variable speed control) DC pumps are completely controllable, the air intake and water throughput can be adjusted via the controller. Protein skimmers can now take full advantage of variable speed pump technology to control the speed (RPM) of the pump.
