The invention provides a double-side double-groove parallel type oil-free vortex air compressor. The double-side double-groove parallel type oil-free vortex air compressor mainly comprises two vortexfixed discs, and one double-side vortex tooth movable disc, vortex teeth are arranged on the end face of one side of each vortex fixed disc, vortex teeth are arranged on the two side end faces of thedouble-side vortex tooth movable disc, and two air compressing channels located on the two sides are jointly defined by the two vortex fixed discs and the double-side vortex tooth movable disc, the vortex teeth on the same end face are arranged to be of a double-groove parallel structure, the air compressing channel on the same side are further separated into two, and the exhaust amount of the vortex air compressor can be improved. Gas is led in from gas inlets in the periphery of the vortex fixed discs, is compressed through multiple compression channels and is discharged out of the center ofthe vortex air compressor. Compared with the prior art, the compressor has the advantages of being large in exhaust amount and more stable in work.
