Danner AP-4 Supreme OXY-FLO Dual Outlet Air Pumps are great for providing oxygen to hydroponic systems. In hydroponic applications, the use of an air pump with an air stone will oxygenate the water and increase the uptake of nutrients by the plant. The oxygen also strengthens the plant’s roots and helps prevents root rot. These air pumps super silent and built to be very durable in even the most extreme growing environments.
