Superflow MV-1050 Compressor

[GWcruiser]

Thought I'd mention Pepboy's has the Superflow MV-1050 on sale, $50. Seems identical to the popular MV-50, just $15 to $30 less money.

First test was to dump air in a 265/70R17 tire to 24 psi, and reinflate to 32 psi (~31.6" tire diameter). Pressures and times verified with a 3-digit pressure gauge accurate to +/-1% and a digital timer.

Based on other reports I expected at least 2 minutes, as long as 4.

After 01:16 (minute-sixteen), checked progress and found the tire had gone from 24.3 to 36.7 psi.

For $50 plus tax, a win.

Cons are wires are undersized, gauge is useless, and if other reports are true of this model, I expect cheapness in the relay.

I bypassed the relay and switch on one of mine years ago will no ill effects. Just say'n

I have a few feet of 10/2 marine dedicated to a future project. But with a minute run time - who cares

my experience is that you get pretty close to reality (of my handheld gauge) if you add 5 to the psi reading on the MV-50 gauge - (between 25 and 40)

The on-board gauge is like 6% and has painted text on the clear plastic that obscures the actual scale to the point it isn't readable... and the fact it isn't fluid filled and vibrating +/-5 psi ... pretty useless. Might be an area they skimped on when making this version.

On the other hand -- if I didn't have other gauges, yeah, I could guess where the pressure is and that'd be better than nothing.

The gauge is pretty accurate with the compressor off but not when it's running. The wiring is a bit light, the fuse holders tend to melt down but usually last a few years. All in all, they are worth every penny. Good to see that they're still available locally.

At 45#'s guage pressure it's almost right on 33#'s real pressure on mine. One other thing you need to watch is that the piston chamber and quick disconnect to the hose get hot as a motha when you air up multiple tires. Careful where you put it away and I don't recommend putting it back into the carry bag until it cools off.

I lost the filter on mine a couple years ago and have been running it without it. No issues so far. I even have a brand new back up I've been carrying around for 2+ years thinking the original would eventually die.
'Still going . . . . . boom, boom, boom, boom . . . ."

Truth be told, I kind of like that it doesn't air up right away because it lets me do other things while it's running at the air up site - clean out trash, bs, grab a dust cutter, bs, restow my gear, bs . . . . .

After one real use, the minute per tire is right there. 26 gauge to 35 gauge after a minute, four tires.

Oddly, seems 90% of the gain is in the first 15 seconds if you believe the on board scale - pressure jumps 25 to 30 when the pump starts (expected) rises to 37 in a few seconds, then creeps to 40 the next 45 seconds. Almost like the reed valves are bleeding over about 30psi.
