Unlike ordinary lubricated gas Corken compressors can compress pressurized, compressors, Corken compressors completely isolate flammable and toxic gases. It is also used to compress the pressurized gas in the compression chamber from harmless gases where oil-free compression or elevated the crankcase. While piston rings seal the piston tightly suction pressures are required. With a large selection of enough for it to do compression work, they do not provide design options available, Corken offers the most versatile enough sealing to isolate the compression chamber from line of small gas compressors in the world. the crankcase. To further seal the compression chamber, a crosshead/piston rod design with seals around the piston rod is required. 4 Chapter 1—Installing Your Corken Compressor 1.1 Location HEX NUT 2” MIN.

This will make it accessible from all sides for Corken Compressors and provide unrestricted air flow for adequate cooling. 1.3 Piping Noise Level: Many factors affect the noise level generated Proper piping design and installation is as important as a by a compressor installation. Several of these, including proper foundation is to a smooth operating compressor. motor noise, piping vibration, foundation/skid design, and Improper piping installation will result in undesirable surrounding structures are outside Corken’s control. The transmission of compressor vibration to the piping. use of sufficient pipe supports, flexible hoses, and proper baseplate/skid support will all reduce noise. Thus, Corken can DO NOT SUPPORT PIPING WITH THE not guarantee a particular noise level from our compressors. COMPRESSOR.
