12 Volt Air Pumps, 25 Watts

The AES DC8 is a 12 VDC diaphragm air pump designed for freshwater aquaculture applications where battery power or vehicle power is used instead of AC electricity. It is the smaller companion to the DC15 and is well suited for bait tanks, livewells, fish transport tanks, and small hatchery systems.

Typical Applications:

Live bait tanks
Fish hauling tanks
Small hatchery tanks
Emergency battery-powered aeration
Remote aquaculture systems
Livewells on boats

Voltage: 12 VDC
Power: 25 W
Current draw: ≈2.1 A

For reliable operation, a 12 V battery or power supply capable of at least 3 amps continuous output is recommended.

DC8 vs. DC15

Feature	DC8	DC15
Power	25 W	80 W
Current Draw	~2.1 A	~6.7 A
Airflow	Up to ~1 CFM	Up to ~2 CFM
Best For	Small tanks and livewells	Larger hauling tanks and hatchery systems

The DC8 is an excellent choice for smaller transport or holding tanks, while the DC15 is better suited where higher airflow or multiple diffusers are required.
