GWSPC Oil free Scroll Vacuum Compressor

GWSPC series oil free scroll vacuum compressor is perfectly used in electric power industry as SF 6 recirculation gas vacuum compressor in high voltage switch testing, with the advantages of compact structure, small size, light weight and low vibration, low noise, low energy consumption, suitable both in vacuum and pressure situation.

GWSPC oil free scroll vacuum compressor is constructed with machine head assembly, crank pin assembly, bracket assembly, air flush assembly, and exhaust valve assembly. Two spiral cylinders, one offset and orbiting against the other fixed with an offset of 180° to form several crescent-shaped pockets of differing sizes. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gas from outside towards the inside thereby pumping the gas from vacuum chamber and compressing.
