With this air pump we have managed to create a very quiet working pump.
There are 3 models with pump outputs of 100, 200 (2 x 100) and 400 (2 x 200) l / h,
The smallest model (3701) has one and the two larger models (3702-3704) each have two separately adjustable air outlets.
Correspondingly, one or two outlets by EHEIM are included in the delivery. The air volume can be adjusted per air outlet directly at the device, additionally at each vent.
So you can adjust the bubbly to taste and demand. Incidentally, vibration-inhibiting rubber anions also contribute to the rest. The air pump is quiet and does not "wander". Or you hang them on the wall. A flap is provided for this purpose.
