3. Eheim Air pump set 3704
The vibration-dampened Air Pump 400 from EHEIM has a pumping capacity of 400 (2 x 200) l/h and features two separately adjustable air outlets. Therefore, two diffusers are included in the delivery. The air volume can be directly and manually adjusted on the device for each air outlet. Additionally, adjustments can also be made at each diffuser. This allows for the bubbling effect to be varied according to taste and need. The pump's quiet operation is further enhanced by vibration-dampening rubber edges. This ensures that the air pump remains stable and does not move around unintentionally. The characteristic hum of a classic air pump is minimized. A tab is also provided for wall mounting. It is ideal for operating air-driven sponge filters or a bottom filter for shrimp aquariums.
