The double screw oil free blower uses a pair of meshing screw rotors to suck in air from the intake end, compressand discharge it to the discharge end during rotation. There is no lubricating oil in the compression chamber, the female and male rotors are driven by synchronous gears to run synchronously. The air delivery is from 3~200m3/min.
Compared with the roots blower, the air delivery fluctuation is smaller. Due to the volumetric compression, the efficiency of screw blower is much higher than that of the roots blower, and the noise of screw blower is much lower.
