Aquarium Air Pump, 3.5W Adjustable Oxygen Quiet 2 Holes with Air Stones and Check Valves for Aquarium Fish Tank

The aquarium air pump is powered by piezoelectric ceramic plate, oil free. The aquarium air pump works very quietly, without electromagnetic interference, and the air stones provide enough oxygen to fish and invertebrates and ensure a more even distribution of oxygen. This aquarium oxygen pump is the size of the palm of your hand, but extremely powerful. The aquarium air pump has two outlets and can pump air into the aquarium with maximum power. Aquarium oxygen pump is a good choice for oxygenation of aquariums with a capacity of less than 450 liters. To minimize the noise generated by the aquarium air pump during operation, we used a dual noise reduction design. First, the aquarium oxygen pump was designed with a thick rectangular shell that prevents side air leakage. Secondly, the aquarium oxygen pump uses elastic rubber feet to absorb vibration and effectively reduce noise. This aquarium air pump also has an electronic adjustment knob to regulate the airflow. The airflow can be precisely adjusted in the range of 2-4L/min to meet the needs of aquariums of different sizes. Box contents: silent oxygen pump, 2 m air hose, 2 air stones, 2 check valves and user manual. The aquarium air pump only needs to be connected to the air stone, and then connected to the aquarium to be used. The aquarium oxygen pump is suitable for freshwater and saltwater aquariums such as fish tanks, aquariums and aquaculture ponds. The size of the aquarium air pump is only 13 x 13 x 10 cm. This powerful, quiet and durable adjustable silent oxygen pump ensures that fish, invertebrates and other inhabitants receive enough oxygen.
