No. They are the same compressors as Emglo was always selling. I have a bulletin from a few years back describing to Emglo dealers about how their compressors would now be sold under the DeWalt name and how they would not be affected and were still considered warranty depots for the new DeWalt line of machines. The parts are the same, the compressor units are the same. And yes, it has a regular cast-iron cylinder that mounts with a flange and bolts, a real piston with real rings and, gasp, even a wristpin! What will they think of next? As far as the oilless goes, the cylinder is like a tin can with a flange on one end. It has a slippery coating on the inside and the "piston" has a bronzed wear ring. Expect both to wear out at least once a year if used regularly or in dusty environments. It doesn't matter if you keep the air filter changed regularly on an oilless, since the bottom of the cylinder is exposed to atmosphere, any contaminants that can adhere to the bottom of the cylinder walls will be dragged up and down 1700 to 3600 times a minute. Ideally, the falling piston would act as a wiper seal to clean the cylinder wall, but at these speeds, we all know that's not going to happen. Low maintenance? We just fixed an oilless this week to the tune of $140 for a cylinder, cooling fan and valve plate. Now he is back again because the crankshaft counterweight has vibrated loose from it's press fit on the end of the motor shaft. We always joke that these machines are a piece of crap, but that there's excellent money in fixing them. We have stacks of cylinder/pison kits on the shelves and believe me, they don't gather dust. They are crap. Every brand.
Crap! Don't buy an oilless.
