Aeration » Air Pumps »
We recommend this air pump for emergency backup air in aquariums, small tanks and even for transporting fish, as it has its own battery. The pump is designed to run continuously on 115V power. When the power shuts off, the pump automatically switches over to its battery backup and continues to run for 28 hours or until power is restored. It features two modes of backup operation: hi – runs 14 hours continuously on full battery mode; low – runs 28 hours on intermittent mode, where the pump automatically is on for 50 seconds, then off for 50 seconds. Utilizes a 6V rechargeable battery (included and replaceable) that is easily accessible. Two 3/16″ outlets provide .07 cfm each of air at 30″ of water depth! One-year warranty. Measures 9 1/4″ x 6 1/4″x 31/4″, weighs 5 lbs.
