Thank you for presenting your product. I hope our communities feedback can inspire you to develop a model suitable for scuba divers. Your build quality appears good.
Comparing your air gun pump with a Rix breathing air compressor will kill your intended market stone dead.
The Rix SA is a divers compressor and a factor of 10 times larger, fully mil-spec certified, NSN/NATO coded and used by real shooters. With available spares and a known service life, a known repair rebuild life expectancy with a long history of use.
Although you could fly anywhere you want, with your compressor but as its a water cooled, until the water in the thing freezes out and cracks the block at altitude I guess.
But you are beginning to compare your air gun compressor with something 10 times larger, designed specifically for divers breathing air, They are worlds apart IMHO comparing this to a Rix is a mistake. Your call. Iain
The compressor can reach about 8,000 psi, we keep it to 5,000 with a burst disc. I have no intention of comparing this comp to a Rix. I was just saying we are small and portable. I ship these comp all over the world, i just empty them of water and they are good.I think this comp is best suited to small fills and convenience. I have plenty of spare parts, we are the sole distributors of these comp worldwide, it takes about 1hr to rebuild a piston ( just Orings), a rebuild kit is $30, it comes with a spare rebuild kit. On average ,we see about 200-300 hrs before a rebuild.

I would have preferred you not compare this with a Rix,
But no matter, here goes:
NO. On a Rix SA-6. You Remove One (1) bolt only
NO. On both the Rix SA-6 and SA-3 You grease only the external bearings
NO. On a Rix there is NO Contamination of grease into the breathing gas
NO. On the Rix SA You cannot get lubricant grease under high temperature or pressure.
NO. Off gassing of the chemical grease compounds into the breathing gas.
Now by comparison I think this compressor of yours needs to be greased internally and if so then the grease is now in contact with the gas you expect us to breathe.
In effect you have contaminated the breathing gas and expect us to breathe
Now as its water cooled and I dare say this is due to the extremely high pressure you appear to claim it can achieve. If so then depending on the stages of compression (I’m guessing its got 3) then you have exceeded the gas temperature at which most grease lubricants will break down and “off gas”.
Now this may be all fine and dandy for air gunners, paint ballers and the frankly silly folk acting as “camouflaged” Rambo mice killers.
But as divers on this forum most take our health and the gas we breathe very seriously.
Besides you would need 16 of them in a row to match a SA-6
and at your $2400 each thats $38,400
Close. Wow………No where near.

I believe there is a conversation on the air gunners forum about the filters that you are using on your compressor. Have you overcome the weaknesses that were discussed there ... no moisture separator? ... no spring in the filter to keep the desiccant tight? ... desiccant just poured in the Diablo housing in direct contact with the pressure chamber walls? ... no PMV? Have you overcome those problems in your system?
