AQQA Rounded Aquarium Air Pump for Freshwater and Saltwater
Two Stainless Steel Outlets
The air pump comes with 2 superior stainless steel outlets that are perfect for running two accessories such as sponge filters and air stones at the same time. It also helps to oxygenate your aquarium, pond, or hydroponic systems with a large amount of dissolved oxygen.
Adjustable Air Flow Rate
To adjust the amount of air, press the "SET" button on the top of the air pump. Different levels of brightness of the blue light indicate different grades of air flow rate. The brighter the blue light, the more air output. 5 seconds after the setting done, the blue light will disappear. The light is not only beautiful but also brings convenience for operation at night.
Note: If you want to turn off the air pump, you can press the "SET" button for 3 seconds or so.
Two Ways to Install the Air Pump
In order to avoid water backflow, there are 2 different ways to install the air pump.
Way 1: Place the air pump below the level of the water surface in the tank with a check valve.
Way 2: Place the air pump 25 cm (approximately 10 inches) higher than the surface of water.
Ultra Quiet & Energy-saving
The air pump is driven by a bearing-less motor which works through magnets. Less vibration brings lower noise than traditional bearing motor driven air pumps. Extra vibration and noise dampening system on the pump further reduced the noise, thereby making it an ultra-quiet air pump.
