Rule Oxygenator Kit, Part No. 252

12V 16.6 GPM Oxygenator Kit by Rule Pumps. High performance live-bait aerators that keep bait and catch alive and healthy in a smaller amount of water. Air is infused with the water at the pump impeller, then millions of micro-fine bubbles are produced and sent gently out of the pump into the livewell. Because the bubbles are so fine, they remain suspended in the water longer; thus more aeration is provided for your delicate bait and catch.
