Water aeration for hydroponics

thingiverse

This device is an innovative solution that replaces a bulky air compressor with a compact water pump, which pushes nutrient-rich solution through a central channel and then flows down a spiral that provides a large surface area for contact with the air. To build one you'll need: - 1x 3D printed column - 1x piece of 40mm drainage pipe (note: not sure if it fits any US standard) - 2x pieces of hose with an internal diameter of 8mm - one to connect pump to column and one to connect pump input to a remote part of the bucket - 1x 12V water submersible water pump with an 8mm hose connector (available on Ebay or Chinese shops for just a couple of euros) - 1x 12V power source - (Optionally) a dc-dc converter - found that pump is too productive and still too loud, so it's better to reduce voltage to 6-7 volts. No estimates have been made yet on how much air this device will actually be able to add, but at least it makes a nice calm sound of running water and plants are still alive (may update this description in the future). The model was created in Fusion360 and is attached to this thing, or available on the link (https://a360.co/2KBvEl7). ### 20.05.2020 Updated A new STL file with a bigger step of spiral has been added.
