The Siphon Sluice - Nano

The Siphon Sluice Nano is an easy to use, beginner friendly way of recovering gold with confidence.

This version of The Siphon Sluice runs -20 mesh (Kitchen Strainer) material and is specifically designed to be a high flow fine gold recovery solution.

It uses a standard 2 liter bottle cut in half as the hopper and with a self feeding system fundamental in its design, the Nano is able to feed itself at a regulated rate.

This system uses a fluid bed gold trap that is highly efficient for fine gold recovery. Using a siphon tube as a discharge, the Nano is able to process fine mesh material, at a fast rate, while maintaining efficiency.

  • The water pump (Not Included) that was used to develop the Nano is a 5v 180 l/h USB water pump. Which “can” run off of a suitable power bank for field use but further testing/research is needed to be sure which power banks can handle the load.

  • In order to cut costs and promote the reuse/recycle mindset, I designed the hopper port to be used with a standard 2 liter plastic bottle. This design should be able to accommodate every prospector globally.

  • This 3D printed system uses PETG filament but the Nano should be kept out of direct sunlight when not in use. If the base print of the single Nano stand does not contact any water, a full PVC base may be needed for use in direct sunlight. ( Update 2026, I have left some Nano parts in the sun all summer, many days reached 95 - 105 degree heat, without water and does not show any signs of deformation. Being that this material is clear and is printed at 220+ c degrees, I believe that there should not be any concerns about leaving this device out in the heat but more testing will need to be done before I can claim it as a fact.)

  • With the pumping pressure pushing in on one side and the siphon effect on the other, The Siphon Sluice series is able to process high volumes of material at a fast rate. While maintaining efficiency with confidence, especially with the lower mesh sizes that the Nano is designed for.
