PVC Fittings Waterlock Syphon air-trap 40mm diameter / 3mm thickness

This is a very compact syphon for 40mm fittings. Inside diameter is 40,5mm.
The bottom part is made square just for printing support.

I created this syphon for a ventilation system where you don't expect high volume of water, just moisture coming form temperature differences. That's why the inside opening under the separation is so small. This can off course be adjusted for higher volumes of water.

Edit: I added one high volume version. SyphonHigh.stl
