Hailea ACO-9820 20W

The Hailea ACO-9820 is a heavy-duty commercial air pump providing 20L/min of high-pressure airflow from a 20W motor, making it one of the most capable units in its size class. It is designed for applications that exceed the capacity of standard hobby pumps — including very large display aquariums, fishroom manifolds serving dozens of tanks, pond aeration, and sump oxygenation. The dual-cylinder design ensures smooth, consistent delivery with minimal pulsation. Built to run 24 hours a day, seven days a week, with a reinforced housing and high-quality internal components. Easy membrane access facilitates routine maintenance.
