An oil-free scroll air compressor, includes two fixed scrolls and a movable scroll with scroll wraps on both sides. The fixed scrolls each are provided on an end surface thereof with scroll wraps. The movable scroll with scroll wraps on both sides is provided on both end surfaces thereof with scroll wraps. The two fixed scrolls and the movable scroll with scroll wraps on both sides together form two gas compression channels located on two sides. The scroll warps on a same end surface are configured as a double-parallel-groove structure, which further divides the gas compression channel on the same side into two gas compression channels, thereby increasing displacement of the scroll air compressor. After a gas is introduced through a gas inlet on a circumferential surface of the fixed scroll, the gas is compressed in multiple compression channels and then discharged from a center of the scroll air compressor.
