A small point for those reading through this post at a later date? Keep in mind that the post referenced above is from 2015 and that it is about a set which was just being developed and with the changes which come along with a new product. That means that we are now about five years later and we should assume that there have been a number of changes in that five years. Having watched how the market works, I keep in mind that things are constantly changed and part of those changes are not to make the product better but to further cut the cost of production. I do not know which way this product may have gone, so just be aware that the review Old Punk gave it in 2015 may or may not be on the same thing we get today.
Well... FAIR points.. and I suppose one could assume I was being a bit err harsh but the reality is it is very difficult to make a precision machined unit (inc. needle valve and solenoids) at a retail price of what $135....and assuming the retailer uses normal markups $70 to the wholesaler...
Now it IS possible from my own research to get decent 2 stage regs China direct for about $50 each (only reg) so there is that.
And using robots one can now manuf precision at a low labor cost.
Call it more as a historical reference and the main function was to get the images of how some of these are built (partially I guess).
I'd have a hard time choosing between one of the above or a beer 1 stage w/ a DIYCO2 post body kit for about $150.
There are still reports of intermittent failures posted here or there of the cheaper 2 stage ones..
They sell "better ones" (always have).......
consider this more of a rambling from a semi-CO2 snob..
OH to add to the design and why it looks "funny" compare to other 2 stage regs.. See here:
Again oldish, Oct-Nov 2016..
(If you own it, feel free to dismantle it. All sealings are done with specially designed o-rings which can be easily assembled back together; to allow easy maintenance of our regulators - this is why we are able to offer 10 years warranty!)
As you can see above, our regulator reduces pressure in two different stages (1st, with one large spring, pressure is reduced to +-10bar/145psi) then gas is redirected to middle chamber, where we have two small springs allowing you to adjust pressure between 0 and 6bar / 90psi.
This diagram is said to be here ..somewhere..
Not my choice of size..
Think I'm harsh.. read that thread..
Best I could do..
Looks to be re-designed.. again..
Completely redesigned with new pressure stabilisation construction. Much larger internal springs are giving safety and precision at the highest level.
Sooooooooooo my biggest beef was with the blue knobbed 2 stage ones..
WHICH are no longer there.. KUDOS!!
