the side of negative (-) wire connected and Oxygen will occur from the side where the Positive (+) wire is connected.
The positive and negative can be connected either way round.
Use as HHO generator if your car don't have computer ECU, or use as H2 - O2 separator if have ECU
You get one HHO generator-separator Asteros A2S and Asteros PWM for controlling the cell.
This cell is using 316L stainless steel tubes thick ~ 18 AWG / 1 mm with size of each tube 1'', and total area 202"
used for HHO production, and because of the no current leakage using 13 amp this cell will produce near
0.9 liters HHO per minute.
The cell will need PWM to be run properly and only distilled water with KOH added. A due ultra slim design
of just 1.9" will fit tiny space in any car. The cell size with barbs and powering bolts 4.2" wide by 5" height.
