The Nomad 2 MAY last longer if used on tube guns filling to 3000 psi (207 bar). They WILL eat their lunch filling to 4350 psi (300 bar) in short order. They develop a “death knock” and will not build pressure. The current draw meter IMO is useless, not a true indicator of an issue as when these fail the meter reads a low amp draw. Using silicone fluid for lubrication is not a good idea ether. The blue LED lighting is cheesy too. I had one that failed within 2 months, returned for warranty repair and then returned again for a refund after a second failure. It didn’t last an hour after the warrant repair. The ONLY single cylinder Chinese compressor that can reliably fill to 300 bar Is a Yong Heng due to better lubrication and water cooling. At high pressures and temperatures no compressor is truly trouble free. Just the nature of the beast. I would NOT push a Spark or clone over 207 bar (3000 psi) ether as I have tried and had failures The manufacturers claim 4500 psi capacity but for how many fills before failure? Air cooled, not many. Just my personal experience with these two different 12 volt air cooled compressors. Using a Yong Heng now with no problems YET, knock on wood.
