Why You’ll Love It
With a powerful piston-driven mechanism that delivers 140-250 GPH airflow, adjustable flow control, and included accessories like air stones, check valves, and tubing, the submarine air pump offers strong aeration and filtration flexibility. Available in two power sizes (5W and 8W), it features a submarine-style look, a waterproof design, and low-hum operation ideal for freshwater or saltwater setups between 20–120 gallons. Its dual outlets can power 2 air accessories and provide oxygen to two fish tanks at the same time.
Key Features
Piston-Driven Dual Outlet Pump
The hygger Submarine Air Pump (HG133) is a silent, durable dual-outlet pump designed for aquariums. More wear-resistant than diaphragm types; powers two outputs simultaneously like air stones or sponge filters, or powers two small tanks from one pump. Built with a piston air mechanism, the pump provides 140–250 GPH and offers stable performance even at deeper depths up to about 4.9 feet. Compatible with all aquarium air-driven equipment, including air stones, sponge filters, ornaments, and under-gravel filters.
Low Hum Sound
Operates quietly thanks to thick ABS housing, motor suspension, sound-dampening feet, and a vibration-reducing build—creates minimal noise even at high flow. Its sound level is 39–48 dB, making it a peaceful aquatic environment for aquatic pets.
Run 2 Air Accessories Together
Its dual outlets can power 2 air accessories and provide oxygen to two fish tanks at the same time. You can use the T or Y connector to combine two ports into one powerful single output.
Adjust Air Flow with Ease
Control the strength of airflow precisely. You can easily adjust airflow via a built-in flow control dial to optimize the performance of air pump drive equipment, appliances, or ornaments, to suit different aquatic pets’ needs. You can have tiny, fast bubbles or medium, less forceful bubbles. The pump is easy to install and use.
Complete Air Pump Kit
Includes a full kit with air tubing, stones, check valves, and suction cups so you can get started right away without buying extras. It includes 1 x air pump, 2 x air tubes, 2 x 4cm air stones, 2 x check valves, and 2 x suction cups. Suitable for air stones, sponge filters, bubble ornaments, under-gravel filters, and other air-driven equipment.
Usage Tips
- Soak air stones for 1–2 hours before use to ensure even bubbling.
- Mount the pump in a stable position; rubber feet reduce vibration and noise.
- Adjust airflow with the dial—use gentle flow for shy fish and stronger flow for filters or heavy aeration.
- Install check valves to prevent backflow when the pump is off.
- Clean air stones and tubing regularly for consistent airflow.
- Choose the 8W model for larger tanks or setups that require higher airflow.
- Not suitable for bedroom use.
- It is recommended for 20–120 gallons.

8W covers two large filters in my 55 gallon tank. Runs very quiet and I have never had any problems with the valves that come with the device.
Good power but mine seems to be getting louder over time. Also like the adjustable flow rate.
This is a great air pump, doesn’t make any noise at all compared to the other brands like xxx and it’s about the same size as the xxx as well, just an inch taller and wider than it (40 gallon size) for comparison. The air flow is great especially with the dial which lets you control how strong you want it to be. And I will be editing this review if the durability does not last, which I doubt of course because all of my other hygger products have lasted me without a problem so far.
I like it pumps air for my deep tank 100 gallon, and the dual outlet for another 80 gallon tanks
