Steady Output: Max Air Flow Rate: 64 GPH; Pressure: 0.016 MPa; Power: 4 W. Perfect for aeration in 10 – 100 gallon fresh water and marine aquariums.(The data is measured with experimental equipment and may deviate slightly from the actual data. The air volume may be insufficient due to the blocked air intake cotton. Please replace the cotton yourself if the air volume is insufficient.)
Adjustable Air Flow: Feature a rotary knob to control the amount of air for dual outputs, allowing for your desired air flow to fully oxygenate your fish tank.
Quiet Operation: The pump emits 25 dB sound under the “Low” mode and maximum 45 dB noise like the hum of a refrigerator under the highest air flow.
