Description
Schego Optimal WS2 aerator pump – high-pressure precision pump for aquariums
The Schego Optimal WS2 aerator pump is a high-performance diaphragm pump with increased pressure output – ideal for aquariums, technical areas and demanding applications. It delivers approx. 250 l/h air flow and handles delivery heights of up to 2 m water column. With only 5 W power consumption, it works extremely quietly (< 38 dB) and efficiently. Equipped with infinitely variable air volume control and integrated on/off switch, it combines maximum flexibility with durable German technology.
Advantages at a glance
- High flow rate of approx. 250 l/h with up to 2 m water column
- Power saving: only 5 W power consumption at 220–240 V / 50 Hz
- Quiet operation with less than 38 dB – low vibration and suitable for living spaces
- Built-in air regulator and on/off switch for easy control
- Robust membrane technology and durable quality “Made in Germany”
Application and Combination
The Schego Optimal WS2 is ideal for aquariums from about 150 l as well as technical applications with high air requirements. It works reliably with a 4/6 mm air hose and should be operated with a check valve. It is particularly effective for air lifters, sponge filters, air vents or protein skimmers. The infinitely variable air regulation allows for sensitive adaptation to the respective application. The pump can be conveniently deactivated via the side switch if necessary.
