  • Compressor
    Publication number: 20090016904
    Abstract: A first tank, a main body of a compressor, an electric motor, and a second tank are combined to form a single assembly. A booster type air compressor as the single assembly including the first tank may be easily carried. The first tank at an inlet side is integrally combined to prevent a pulsation in the supplied compressed air for eliminating the drain contained in the compressed air. The air compressor, thus, is structured to discharge high compressed air from a high-pressure outlet joint formed on the second tank.
