Powerful motor pumps drive precision Needle Wheel Rotors to introduce large amounts of air and water into the skimmer body. This is done without compromising continuous delivery and velocity due to the turbulence reducing bubble plate chamber. The result is a consistent foam head and nutrient extraction. Vertex™ IN-Series Skimmers represent the Ultimate solution to noise reduction. Rotors engineered with the incredible strength of Rare Earth Phosphor Magnets and the frictionless ride of ceramic shafts, polished to an exceptionally high gloss, ensure that the entire impeller assembly spins with amazingly nominal resistance and vibration.
