Fair enough! Congratulations Scott. :D

I'm glad they can compete, this will bring prices into a reasonable level.
Both can continue doing business and try and build the best systems at the best prices.

I'm pretty sure none of them are making the big bucks with a 3rd house , jet boat and aircraft. They are working hard to make a living.
Id hope they both can keep the doors open and live decently though.

This compressor seems cool but it’s all really expensive. Too bad they had a court battle because people are sew crazy.
I’m personally happy with my Beth bravo running straight on oxygen generators.

This is such a hard topic because both of them are as nice to their customers as each other. Especially calx ann, she has nothing to do with any of this and is a very nice person, nicer then myself possibly. So i dont see what the point of blowing up her social life along with someone who has done nothing but helped you and asked for nothing in return. In reality wal-mart destroyed every business in america with forign slave labor and where do we all go get our grocerys. You see what im saying here? As for product h.v.o wins and ive owned both. Just keepn it 100.

Misfitman- Well since you asked... The oxy frog i had never even worked. He uses hose clamps for his high pressure lines inside the machine, pressures rated too high for hose clamps as indicated by the manufacuter of the hose clamps. Frog asked me to go to auto zone and get fancy hose clamps, those blew too as they are not rated high enouf either. Every time you want to service the inside of the unit there is a mess of wires and connections everywhere that makes you likely to do more harm then good trying to fix anything. Not to mention getting in there to begin with is a nearly impossible game of "shimmy shimmy", sorry best way i could describe it lol. I never got to even use it. When i talked to the guy who sells his refub concentrators he said "wow, hes still having that problem? I thought he fixed that". Frog acted like this was the first time this happend.......

As for hvo i never had 1 damn problem the whole time. And if i did it would be easy to just pop the top open and take a look. I came back from a surgery this summer and my hvo was acting funny and turning off when it shouldnt, not turning on concentrators, ect. I was pissed because all they could tell me was its not the machine and theyd chip in for me to get an electritian because they thought i had it wirerd wrong to the breaker. After telling them i have everything plugged in and wired right for the 100th time i preaty much screamed at them and sent it back. They were nice the whole time and even replaced something inside for me but said again....nothing is wrong and its my electric. I do my own electric so i knew it was fine and replaced the outlets...still broke..Then, i changed the breaker and BOOM everythings fine. Do i wish they told me to change the breaker from the jump? Yeh sure. But in reality they did everything they could do and more to get me melting again. No hiccups since.

As for lowtide's situation threw this whole ordeal hes the one i feel the most sorry for, all he was trying to do was help the community and he almost ended up in high tide, no pun intended and i think he deserves an apology from you know who.

my home built unit is still pumping strong to the people i sold it to, been almost 4 years.

sparko your comment is the reason i've tried to tell everyone to build their own system.

You need to be familiar with it when it needs maintenance.

Just like a car you need to change the oil and fluids, put gas in ect...

If you can't do those things, imo you shouldn't be driving.

Cons to pressure relief valve set to 2 psi .... to compressor. To holding tank to regulator its really that easy people make it more complicated than it needs to be imo with all the control boxes ..

Mute

11-23-2018, 08:36 AM

^i did the same, except each con had a relief valve and the compressor had one on the inlet also.

only did that because with one it was still kicking off the weakest link.

after adding the extras, no issues.

not sure what the rating on the plastic oneway valves i used, but it was very low. Ones i used were from inside old/broken concentrators.

I dont think it will be long untill everyone is just making there own systems. Someone will post an in depth video or thread sooner or later, its only a matter of time im sure. Mtn glass and abr will probably even sell the parts in kits, kinda like how they do with enails on some websites. Just a prediction.

People were making their own and teaching each other how long before these businesses got started. That's the entire point of the court ruling we're talking about here (see original post).

Have been running oxyfrog since March 2016 and aside from some startup issues with the control box, this thing has not had a hiccup in all that time. The issues had to do with undersized wiring for the size of the system (5 concentrators, plus the compressor). I kept burning out the thermal resets over and over. Replaced the connecting wires with a new wiring harness and have not had any issues in 2 years. So I am pretty happy with the system. I also looked hard and long at HVO during the process and the decision was not an easy one.

In the conversation of HVO vs. Oxyfrog....I've recently seen Scott from OxyFrog talking about his Active Compression Control (ACC). It seems like a really cool thing that would be a pain in the ass to program. I'm thinking HVO doesn't have anything like that in their system....wouldn't this give an OxygenFrog a clear advantage over HVO?

no. it was discussed here a while back.

personally i came to the conclusion that it is just an adjustable check-valve.

the digital pressure control unit used doesn't support that type of programming.

if hvo setup there system right i think the brain in that setup would actually support actual programming.

not really saying one would work better or not.

just kinda like analog vs digital imo

more than one way to skin a cat and i'm sure both have there pro's and cons.

i'm more of an analog type

I disagree, I've been pretty sure for a while the active compression control is just a small 1/2 hp or 1hp Variable frequency drive like the ones Wolf Automation sells. Scott always cleverly dodges my comments when I mention VFD's. All that would have to be done is adjust the VFD based on pressure/vacuum in the concentrator line.

HVO seems to think they are not needed, and they certainly get good results without it. I'm with mute, an adjustable check valve does the same thing and analog is always more dependable.

Mute

12-19-2018, 05:23 AM

The "cracking" pressure or the pressure required to open the diaphragm in the check-valve, is actually different on the "adjustable" check-valves.

It is usually given in a range such as 50-100psi.

Opening pressure being 50psi minimum and 100psi maximum.

So even if the holding tank dips below 50psi, the compressor will still pull the same amount of oxygen it would at 50psi, keeping the purity in a tighter range.

I think i'm going to do a small write up on the low-pressure oxygen storage set-ups like these, with a simple drawing. that way it will clear up some confusing terms or configurations.

Oneiros

12-19-2018, 10:45 AM

Has anyone actually used an adjustable check valve with their system? I got a 50-100psi one and used a craftsman shop compressor to measure/set the cracking pressure to 80psi, but when I attempted to use it inline, my Gast really struggled. I ended up pulling it out as I was less concerned about overdrawing the oxycons than beating up the compressor. Not sure what the issue was or if I made some stupid mistake, but I figured I'd play around with it again if/when I need to rebuild the compressor or change up the system down the line.

Mute

12-19-2018, 11:01 AM

i actually left mine out of the system due to the pressures staying above 50.

If i were to use it, i'd set it to the lowest setting and adjust the resistance if needed.

Sparko

12-23-2018, 10:55 AM

I think alot of the time when people build something their looking for that one key factor that sets your product apart from the rest. The oxygen frogs thing that keeps un pure oxygen out while the concentrators are getting warmed up sounds cool but from my testing the HVO doesnt produce any different results. Im not a fumer but my colors that need extra oxy stay true and i never had a problem getting an oxy flame under any circumstance. I think theres so much oxy compressed in the tank at full purity that the 2 minutes befor its pure really doesnt matter. I think its probably more important to have a purity sensor on your concentrator then your compressor system.

If i were to use it, i'd set it to the lowest setting and adjust the resistance if needed.

That would seem to defeat the point of putting it inline, no?

My system is set up to draw off of 4 10lpm oxycons and is pretty much at optimum efficiency right at 80psi. For over 80psi, I have a a blowoff valve plumbed in before the compressor, to vent the excess o2.

But if I wanted to put the check valve in-line, the whole point of it would be to keep the compressor working as though there was 80psi in the tank, even if I brought the tank pressure below that point. Setting the check valve to 50psi would mean that it would effectively be doing nothing unless I majorly overdrew the tank, right? It wouldn't matter unless things got down to 50psi, as I understand it. Essentially, most of the time I overdraw the tank, I wind up maybe at 70psi, rarely below that, so an adjustable check valve set at 50psi wouldn't do anything for me.

Has anyone actually used an adjustable check valve in their setup? I've seen some chatter, but never any actual real world experience. Based on my own experience, it was easier to skip the valve, but if I'm missing something, I'd like to wrap my head around it.

yeah, i agree with that.

Same reason i didn't put it in.

there is no reason it wouldn't work.

the only benefit i could see if you never went below 50 psi with an adjustable check-valve, would be the initial fill. It would be more pure, initially.

Seriously? Your not pulling my chain Mute? My cousin builds his own cnc machines and agrees with all of you all in that building these things is a breeze. He builds custom parts for drones on his cnc machines and is always looking for a way to improve various gadgets. Im really looking forward to seeing what he comes up with for the HVO machine. Right now hes drawing up some stuff in cad for me. Think reamers with heat fins, and reamers made of titanium (for fun experiment) lol. I plan on coming here to sell them first.

Reason i ask is my Mighty Max drone runs super hot compared to the Mighty Mite. I noticed they reversed the computer fan on the green box. It was pushing in air instead of pulling it threw the unit like on my original main head unit. I can only guess they changed this because of the MAX over heating. The room has to be considerably cooler for the MAX compared to the Mite or it will trip the motor and turn off. I wish I just got the mighty mite drone and not the max.

Sounds like well all be tinkering on these things for years to come.

In the last couple years Iv built a wood lathe, belt sander, glass grinder, a cnc engraver, cnc laser engraver , a 3d printer and a small race motor.
The 3D printer has 2 computers, 2 heaters, 4 stepper motors. These thing are getting bad ass now days.

Building an oxygen system here in 2019 is child play. It wont be long till we get cryocoolers to make liquid nitrogen for a liquid oxygen distillery and trapping our own liquid oxygen.

Its not magic, oxygen is everywhere,21% go on and get you some.
