What brand compressor(s) do you like and recommend?
(Serious question, I don't mean to be sarcastic at all)
I don't like any of them LOL

its just my day job I do it the best of my ability.
As a long term ex commercial North Sea diver I don't recommend any brand or sell you anything.
I just do my job get very well paid and live a life by the grace of God I never expected or deserved.
I prefer to inform than recommend and with that if it educates someone into making an informed choice then great I have served a useful purpose.
As long as you realise your being lied to by the recreational scuba industry in general and by scuba compressor manufacturers in particular then that at least is a start in the right direction.
Want proof? Then ask yourself why you never see a compressor manufacturer, clients rep, salesman or even a scuba shop retailer on these boards defending their compressor product or position.
As long as what we say is true and equally important that we can defend our position and that the moderators don't get too much flack or the adverting revenue stream isn't affected then for the time being we can enjoy our free speech and platform. For now I guess but no likes or recommendations.
The purpose of my response to the new 3 stage Coltri MCH-6 Vapourware model was simply to outline a consideration that not all engineering metal process are good for the divers human health.
While Ni–SiC coatings offer superior mechanical properties, their enhanced Ni ion release in various media, particularly in biological environments, poses significant and very well known environmental and health risks that have been ignored and kept from informing fellow divers
Also Mixing synthetic chemical digesters (oils) polyolefin and triesters with elevated oxygen nitrox concentrations in an oil lubricated air compressor is also another long term detrimental health issue for divers but what you don't test for you may never know. You do now.
