""" So are you saying in a situation where I was running a Hiblow at say 3psi the true impact on the hiblow would really be more like 5psi if using a Vertex diffuser with it?"""
Cody Note - Well it depends. I do not know the exact PSI back pressure that is needed to operate the Vertex diffusers. That discussion is somewhere in the old posts. The final pressure of a Hiblow at 3 psi with Vertex diffuser could be any where from 1 to 3 additional PSI, It would be best to check with a Vertex retailer or find the old PBoss post that discussed this topic. As I recall the discussion was around 3-4 years ago. I doubt I saved this thread. 'esshup' I think was a part of this thread, he should know and was going to take apart a Vertex diffuser to see how it was made. Maybe some member can help with this?.
I had a diffuser stick closed this Fall. At a customers, and I didn't have an extra diffuser with me. I will be going there in a few weeks to swap it out and will be taking the bad one apart. To fix it I just took the diffuser off of the base, stuck a screwdriver in the diffuser and whacked it with the crescent wrench I had in the boat. I only got to hit it once, the dang screwdriver jumped out of the diffuser and made a direct hit in the pond, never to be seen again. Air was flowing, so I didn't care at that point as the compressor wasn't going to be turned off for the winter. I will be dissecting it soon, and might do the same to a good one to see the difference if I can't determine what went wrong.
