Frabill's Aqua-Life aerator systems have been specifically designed and tested to keep baitfish healthy and active. This portable aerator converts up to a 100-gallon cooler or livewell into an oxygen-rich aquarium. Operation is whisper quiet – so quiet you'll barely know it's on. The system also uses a specialized micro-bubble oxygen diffuser to produce a tiny cloud of bubbles that won't disrupt or damage delicate baitfish.
