Safety Precautions

For dry and clean gas applications. Gas temperature must be below 122°F (50°C). Avoid direct intake of liquids, excessive water vapor, particles, dust, and corrosive gases unless the pump is specifically configured for these conditions.

Technical Resources & Support

Access the technical resources you need for your GWSPC oil-free scroll compressor, including operation and installation manuals and 3D CAD models.
Whether you are preparing for system integration, piping installation, or routine maintenance, our support center provides practical documentation and dimensional models to help you keep your compression system operating reliably.

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.
