Dual Air Outlet The aquarium air pump features a dual air outlet design, allowing it to supply oxygen to two or more aquariums simultaneously. It also supports positioning two air diffusers at different locations for more uniform oxygen distribution. This enhances the efficiency of oxygen transfer into the water and promotes the health of fish and aquatic plants. Powerful and Adjustable This 8W aquarium air pump delivers strong air pressure with a maximum flow rate of 2 x 3 L/min. It includes a control knob to adjust power and airflow according to tank size. Airflow can be reduced at night to minimize noise. Suitable for aquariums ranging from 5 to 300 liters. Quiet and Shockproof Designed with a noise reduction system, the pump includes a durable housing, an oil-free piezoelectric ceramic plate, and four vibration-absorbing rubber feet. Using two air hoses connected to separate outlets may help reduce noise levels. Note: Higher airflow settings may increase sound output.
