Keurig K140 K Cup Coffee Brewer

Still for sale on the Keurig website as a commercial model, the Keurig K140/K145 is advertised as a heavy duty home or office coffee maker.

It also features the ability to drain the heater tank.

For the most part, it operates much like many of the other Keurig models with 3 cup sizes. And it also has a smaller 48 oz water reservoir, unlike some of the much larger reservoirs on newer units.
