HHOG 2 EPD v2 Explosive Pressure Dissipator Safety HHO

http://www.hhoglabs.com READ FURTHER!
We have renamed this device to better reflect it's purpose. EPD stand for "Explosive Pressure Dissipator".
We are excited to show you guys our newest safety mechanism. It is actually a metamorphasis of our early "Pop-off" style EPD. NOW, after our research into the AutoBubbler, we have managed to tuck a neat little auto resetting head into the EPD. You no longer have to chase down a blow-off cap! The unit will blow open in the event of a flashback and dispell the blast. It will automatically reseal itself, so your HHO generator can continue pumping HHO!
We will also post a Tutorial video on this little gem as soon as we can. So STAY TUNED!

i love the dramatic music as if presenting some cutting edge technology hahahaha.

HAHA. I know. We had to spiff it up, somehow!!! :-)

I would like to see this working on a typical blow molded bubbler about half full of HHO. My tests have blown the lid off, using a smaller pressure valve. One time it blew out the bottom barbed fitting out of the bubbler. Another time it split the bubbler.  One time it BLEW the valve out of the bubbler itself.

Im not sure these can be used on blow molded bubblers, I would like to see how your's performs on a typical bubbler. The one I have used works great on PVC bubblers.

Apparently my first post didn't get to you.

We have never tested this with a blow molded bubbler. Only PVC. If you were to attempt a pressure relief valve similar to this, it would have to open at a VERY low pressure. I don't recommend it. This would be a problem on systems that generate more than 2Lpm, though. Could have leaks. We have a new EPD-Enhanced bubbler on hhoglabs . com (remove spaces) website. You are welcome to look, and see if it gives you any ideas for your own purposes. Steve

@InstallGuys Hi Steve, I want your advice, Dry Cell or Wet Cell? Thank you for share your knowledge.

[InstallGuys]

@arthus1971 Deffinitely Dry Cells...all the way.

what is this epic music in the background! awesomeness :|

good work guys....................keep it up

Bravoooo!

Yes you are right PVC, ABS. thicker types is about the only bubblers I think this will work on, not blow molded type, just not enough strength in the caps/bubbler housing.

Also, to be clear, I never tried your exact design, I made myself a small 1/2" one with a weak spring, based on a similar in design to yours but not exactly. And the other type was one from Grainger, which blew the lids off.

I was hoping your design might work better than the ones I tried, ie release at lower PSI etc

Another thought.

DISCLAIMER: We do not recommend using check valves as flashback arrestors!

HOWEVER...we have had pretty good success with stopping flashbacks with check valves. It works about 80-90% of the time. Also, the orientation of "floating diaphragm" check valves matter. Point it UP! So, I recommend putting a check valve on top of your bubbler for the gas output, not simply a barb. This may greatly reduce the chance of a flashback getting to the bubbler. They make threaded versions.
