What a great machine!
It is all that they said it would be. And quiet too. A must for all workshops.

Defective out of the box
I was very excited to receive my Emglo M790-HC4V air compressor today. When ordering it, I really liked the size and layout of the controls and gauges. Unfortunatly, it arrived dead on arrival. After I installed the oil in the compresor crankcase and turned it on, the motor hummed loudly as though it had a shorted winding and refused to turn the compressor. I WAS NOT HAPPY. OK, now I have to return this thing... After close examination, I was surprised to see that the compressor / motor unit is mostly a white metal casting that is secured to the chassis with self tapping screws. This low cost "cheap and dirty" method of securing the unit to the frame makes me wonder abut the quality of the internal design....

Thanks Emglo but no thanks.

good, fast compressor
This compressor is great. It rebounds very fast. When i first got mine it made a funny noise, alot like a little gas engine trying to start,and it stillmakes a sorter version the first time i turn it on.It has plenty of power. Be sure the swithch to a lighter oil in winter use, mine has triped a 15 amp circut when starting up on a cold morning.I like having the splitter for youe air hoses right in the middle of the two tanks, it eliminate a splitter which ten to leak after a while.There are nice big rummber feet on the bottom to keep it on the ground nice and sturdy. you can hardly drag it even if you try.

2001 Model
I just purchased a Master Series Model 800 (which is supposed to be the latest version of the 790) it is one sweet compressor. I've been running it indoors, and although it isn't exactly quiet, it makes less noise than I expected. Also, it has yet to trip a 15 amp breaker (something I was concerned about). The controls are really well placed and the dual quick connects are awesome. My finish and brad nailers hardly even make it run.

Mini Sherman Tank
I love this little tank, strong, secure, quiet, well designed, and good workmanship. It runs all day without care. The dual hookups and gauges are a nice feature, the hoses aren't anchored to the tank plumbing like on most portables
