Airlift Pump for Aquarium and Pond Filtration

This airlift pump is designed for aquariums and small ponds to provide efficient water circulation and aeration. 

The construction uses rising air bubbles to move water, which means there are no moving parts, making it quiet, energy-efficient, and low-maintenance.

The model features an integrated chamber with multiple small holes for even air distribution. It is optimized for 3D printing and connects directly to a 16 mm water pipe with a 4.5 mm air inlet.

BETA! I have added a parametric model, so it's possible to customize it for your needs. Please keep in mind that you get the model file but not all the print settings, so you might want to make sure it's aligned in the correct position and adjust other settings accordingly.
