Description
S-1800 aquarium air pump with built-in DC power backup.
The pump can run under two operations, either by plugging the unit into the mains or running using the internal battery.
Ideally, the system is used plugged into the mains and with the internal battery as a backup due to power cuts, etc.
During normal AC operation, the power to the system is constant.
When using with the internal battery you have three modes:
Low power
Standard power
Discontinuous power (gives small bursts every few seconds to conserve power)
This air pump is ideally suited to supplying air pressure to under gravel and box filters, air stones, and protein skimmers that use ceramic air stones. It is easily adjustable, with control to alter the magnetic circuit on top of the pump. Both are long-lasting and efficient.
