Air Pumps

The alternatives

Other contenders

• EHEIM air400

  Choose the EHEIM air400 when you want a higher nominal output for two direct air lines. It is rated at 400 l/h with two outlets, compared with the air200 at 200 l/h.¹³

Buying advice

• Match the pump to the depth and airflow requirements of your diffuser or air driven filter. A nominal output and a maximum lift are separate ratings, not a promise of that output at every depth.¹

For nano tanks and small aquariums

Consider the air100 when you need one direct air line and its nominal 100 l/h output suits the connected device. A small tank does not by itself establish the airflow needed.²

• EHEIM air100

For deep tanks

The air200 lists a 2 m maximum lift. Check the pump and diffuser instructions against the depth where you will place the air device before choosing it.¹

For running several devices from one pump

Choose the air200 when you want two separate air lines connected directly to one pump. Its two outlets avoid needing to split a single outlet for those two lines.¹

For large tanks and fish rooms

Consider the air400 for its higher nominal output of 400 l/h and two direct air outlets. Choose by the connected devices and their depth rather than tank size alone.³
