Eheim Adjustable Air Pump 200

There are three models available with air output rates of 100 l/h, 200 l/h (2 × 100), and 400 l/h (2 × 200). The smallest unit includes one air outlet, while the two larger models feature two independently adjustable outlets. Each pump is supplied with one or two EHEIM diffusors, depending on the model.

You can precisely control the airflow at each outlet on the pump, as well as directly on each diffusor—allowing you to create a customized bubble pattern that suits your setup.

Bonus feature: Vibration-dampening rubber feet help ensure quiet, stable operation—keeping the pump in place without sliding or “walking” across surfaces. Alternatively, you can mount it vertically on the aquarium glass using the built-in hanging hook designed specifically for this purpose.
