Find a productProduct description
This dual-outlet air pump is intended for aquarium keepers who need continuous aeration for a single tank or for two separate setups. Its 3 W power draw and compact 11 x 6 x 5 cm body make it a low-consumption option that can be placed out of sight behind or beside the aquarium.
Why it matters
- Two independent outlets: each outlet delivers 3.4 l/min and can feed a separate air stone, or two aquariums.
- Stepless flow control: the output can be adjusted smoothly to match the aeration needs of a given tank.
- Quiet membrane motor: combined with soft rubber feet, the pump is designed to run with minimal noise.
- Continuous operation and splash resistance: the unit is rated for 24/7 operation and is IPX4 splash resistant, so accidental water contact during water changes is tolerated.
