gmohr, thank you for your response. At the time when I was researching compressors I decided on the LC-110 made by Coltri because it was less expensive than the HPDAVV compressor which appeared to be very similar in construct. I would like to thank you for your research done and would like to ask, if possible, if you could cite your references to support the assertion made that 'HPDAVV is the one of worlds largest manufacturer of HPA compressors'. Thank you in advance!
I suspect, but cannot assert, that HPDAVV indeed manufacturers compressors both unique and copy-cat such as the HPDAVV Coltri-style compressor. I believe, but cannot assert, that various US importers re-style or re-brand them to carry their brand name. I suspect, but cannot assert, there's a whole lot of re-branding happening with compressors. We know it as fact, or at least observation, with Daystate LC-110 -> Coltri MCH-3 EM LC.
Based on failure rates of the Air Venturi line of compressor offerings it is my personal opinion, not meant to sway anyone for or against it, that they would make exceptional boat anchors.
