Ive been running 2 viair 480s for a year or so now and knock on wood no issues. before that i had 2 viar 450s that i ran for 4 years absolutly tortured them sold them to a friend and are still kicking. I had 2 viar 380s and had nothing but problems with them. these are all using filters and a beefy power source. imo the viair qualitly has went downhill over the years.
They had a bit of a name in the past, but they were some of the first to bring these in, and essentially created the market segment in the process. They hit magazines and car shows hard, as well. They were the best because there was shit-all else available, and everyone knew the name.
They sold because the market kicked up when people were hopping about on air springs more often, and nothing said clean like a rack of chrome Viair compressors. Now people know better, and you'll find chromed Oasis units under some of the nicer low-riders, mini-trucks, and tuned imports.
Viair just buys the models set up for their purposes; most of which are designed for tank use. The rest are identical to the cheap ones that have been mentioned.
It's the same shit. ARB buys ones set up their way, and pays extra for all the cosmetic heat sinks. They brag about bearings, but all of them have good bearings. It's like when I advertise a product as "genuine", or "authentic". People all of a sudden think there are fakes out there...
Works every time. I sell faster and get more money.
You can get any of those things straight from China without the stickers if you want, but the MV50 is, as I said, the way to go for a portable compressor. I know I complain about the stuff, but shit just never works out right for me, that's all.
Cheers,
