4 FD151 Gas Compressor
Corken industrial gas compressors are unique
among compressors their size. Unlike ordinary
lubricated gas compressors, Corken compressors
completely isolate the pressurized gas in the
compression chamber from the crankcase. While
piston rings seal the piston tightly enough for it to do
compression work, they do not provide enough
sealing to isolate the compression chamber from the
crankcase. To further seal the compression chamber,
a crosshead/piston rod design with seals around the
piston rod is required (see Figure 1.1A).
By utilizing specialized piston-rod sealing systems,
Corken compressors can compress pressurized,
flammable and toxic gases. It is also used to
compress harmless gases where oil-free
compression or elevated suction pressures are
required. With a numerous selection of design
options available, Corken offers the most versatile
line of small gas compressors in the world.
