1. The fish tank air pump has a semi-transparent ABS case and pure copper motor with a novel design. It has an 8W input voltage of AC110-120V/60Hz, 10L/min(150GPH) air flow, and 0.03Mpa air pressure, suitable for fish tanks up to 160 gallons.
2. The air pump's air output can be adjusted by rotating the top button to turn it on and off, with unlimited adjustment of air volume for easy use with one hand.
3. An ultra-silent air pump, driven by a suspended double duplex air chamber for strong airflow and reduced friction, reducing noise to less than 35 dB when in use. Rubber feet and an all-in-one space-capsule pump body also contribute to effective noise insulation.
4. Precautions for use include installing the Y Shunt Tube if there is only one air outlet, adding a check valve if the pump is below the water level, and noting the direction of installation when using the check valve with the bubble stone.
5. The packaging includes 1 air pump, 2 bubble stones, 2 check valves, 1 air hose (9.8ft), and 1 Y Shunt Tube, suitable for use in freshwater or saltwater aquariums.
