Central Pneumatic 3-gallon air compressor
1/4 horsepower motor
I could have justified buying a small air compressor years ago, but never did. In addition to all the tires on the vehicles, I have two inflatable tires on my bicycle, two tires on the dolly (the washing machine moving kind), and a basketball. Unless you own an air tank or a compressor, you're looking at fifty cents and a trip to the gas station any time one of those things needs air. Eventually those trips add up and the compressor will pay for itself. Mine has paid for itself and then some. I use it to blow dust off computer hardware, book cases, or any other place that's hard to reach with an ordinary duster. A pressure regulator adjusts the force of the outgoing stream up or down and can be changed by turning a dial. A second regulator and gauge show the pressure in the tank itself. There might be 80 pounds of pressure in the tank but I only use 15 of it to blow out keyboards and dust desk tops. I blow off the backs of my PC's every three or four months. The power supply fan and the grill covering it are notorious dust collectors and compressed air, gentle compressed air, is the perfect ticket for cleaning them. In the garage I use it to blow off my work bench and clean tools after use. Out there where finesse isn't an issue, I dial the pressure up a bit to about 60 psi. It's ideal for cleaning sawdust off the table saw or saw horses after I've been cutting wood.
