Master Flow MF-1050 Air Compressor

Used this a couple times now, so figured I can comment. Mixed reviews out there on this, some saying it gets too hot, some saying not. News flash, ALL of these types of air compressors get hot, as does this, but nothing out of the ordinary, and I believe this one, compared to other ones I have used, does not heat up as much. I'm using it for 37s, airing down to 8 psi, and then back up to 27 psi. Didn't time it, but seemed a decent speed. Gives me enough time to deal with other things like reconnecting sway bars and putting little things away for each tire. Gauge, as with most, isn't accurate, and I use another one for checking the psi. I air up a little more than I have to and drop it back down with my deflator. Bag is a nice touch, zippers could be stronger, but treat it easy, and it will last. Was going to spend big $ for a complete Viair system, but thought - why spend a lot on something that may be on board, may air up slightly faster, and will be another pain to install, when I can just buy a cheaper option like this, and put that money elsewhere. The less crap hooked up to the vehicle the better too, without the LED lighting and other accessories, and I can now take this in my other vehicle in the winter for emergency use as well. EDIT Dec 2019 - I've used this compressor now for 3 years, and I do a lot of rock crawling, and constant back and forth from 25-27 to 7-9 PSI. This compressor has never let me down, dead of summer or -20c in winter. I find with people with expensive on board air I am not far behind being aired up from when they are, and others with even more expensive portable compressors are not as quick as mine. The bag, I recall, had complaints from people, but using mine constantly from May until Nov each year has had no rip or issue with the zipper. The only problem I have is that the fuse and wire out each end is getting hot, so I suspect the fuse holder isn't beef enough for the current, which I'll swap out sometime soon with a cheap upgrade. All in all still a great and tough little tool.

Iba a comprar el 1040 pero me gusta 4x4 y este es extremadamente uso rudo, si quieres salir rápido de apuros y genial, me da miedo usarlo mientras llueve porque va conectado a la pila pero es genial

Previous reviews have faulted this product for the crap hose, the crap screw-on fitting and the weird hose fitting that made it hard to use a regular air hose if you wanted. The hose is still crap. The screw-on valve is still crap, totally unusable. But!!! The unit I received about March 2015 had a standard air hose fitting and I was able to get a standard air hose and hook it right up no problem. I have used this compressor to air the shocks in my camper and add air to a flat quad tire. It works great! It can deliver high pressures (>70 pounds) with no trouble at all. The CMF is over rated but not by much. It will fill your tire quickly. A very nice air compressor. Too bad they still ship it with a crap hose but at least now it's easy to replace that crap hose with something better.

Bueno Este es mi segundo masterfollow el primero que tenía dure muchos años con él mas de 10 años lo use para camiones para carros albercas inflablables etc hasta que alguien lo necesitaba mas que yo y se lo llevo excelente producto

I filled up all 4 tires before buddy had one done. Litty pump indeed
