The utility model relates to the field of air compressors, in particular to a double-screw air compressor which comprises an air compressor shell, an air suction mechanism is connected to the top of the air compressor shell in a welded mode, and an oil gas compressing and discharging mechanism is connected to the bottom of the air compressor shell in a welded mode. A secondary filtering oil circulating pipe is welded to the outer wall of the air compressor shell, a main shaft cover plate is welded to one side of the oil gas compressing and discharging mechanism, an oil pipe groove is formed in the other side of the main shaft cover plate, an oil spraying pipe is connected to the inner wall of the oil pipe groove in a clamped mode, and an oil storage compartment is formed in one end of the oil spraying pipe. By arranging the secondary filtering oil circulating pipe, lubricating oil is recycled, loss is reduced, air entering is accelerated by arranging the air suction mechanism, air is preliminarily filtered, a
