Oil-Free Compressor CONTRIBUTING TO THE WORLD AND LOOKING INTO THE FUTURE WITH THE LATEST TECHNOLOGY Medium and High Pressure Oil-Free Compressor Many High References • Developed by our long years of experiences in compressor manufacturing, backed up by modern technologies and our recent integrated research works. • Fabricated by the governmentally certified workshop of our company, officially entitled to test and fabricate high-pressure gas handling installations for advanced and diversified technological needs. Our company has facilities to take up complete works, including design,...

FEATURES High reliability: Fabricated by using only high quality materials after repeated tests against corrosion and abrasion. Our excellent manufacturing facilities, supported by modern technologies and first class quality controls system, guarantee highly stabilized performance for long-term compressor operation. Economical overall operation guaranteed by simplified operation and maintenance systems: For that purpose, not only our patented Dual Control System but also our Multiple operation control system and integrated control system enable simplified selection of optimum operational...

Oil-Free Compressor •Cylinder head Independent sealings are provided for both gas and cooling water sides. There is no leakage of gas and cooling water under such system. •Suction and discharge valves Both are guideless type and are perfectly treated against both corrosion and abrasion. •Rod packing Packing elements made of special carbon or TFE (tetrafluoroethylene), composite are located one above the other in a gland holder. The gland holder is so designed that cylinder pressure can be used as a pilot pressure to press the packing. Elements from the backside against the piston rod....

•Rider ring Rider ring made of special carbon or TFE composite is used. Both have long life, and in particular, endless type is for longer time of service, since this type is not affected by backpressure. •Piston ring Piston ring made of special carbon or TFE composite is used. Both have excellent property against leakage and abrasion, and have twice as much of life of our previous type.

Oil-Free Compressor ROD PACKING KEEPS STABILIZED PERFORMANCE FOR LONG-TERM OPERATION ROD PACKING ASSEMBLY • acking holder is so made that it takes cylinder pressure P to the backside of rod packing, to utilize cylinder pressure s pilot pressure for rod packing. Thanks to the excellent self-sealing effect of this patented system, there is almost no possibility of gas leakage.

4 TYPES OF ROD PACKING ARRANGEMENT Type 1 APPLICATION Instrument air Inert gas Rod packing Oil wiper ring Oil seal Type 2 Process gas buffer pressure APPLICATION High purity gas (Suitable for Instrumentation Air and Inert Gas) Gas Seal: Sealing is made by using Rod Packing so that gas from Cylinder will not leak at Rod part. Oil Seal: Scraping of oil attached to Piston Rod entering from Crank case is made at Oil Seal. In addition, further prevention from oil transfer is made at Oil proof plate. (Suitable for High-Purity Gas which is severely undesired for composition change of compressed...

Oil-Free Compressor PISTON RING, RIDER RING Piston nut Piston washer Rider ring Tension ring Piston Piston washer Piston ring • umber of rings and materials are carefully selected N through our long experience in the past, considering gas analysis as well as suction and discharge pressures and temperatures. • ual type TFE composite piston ring is used for better D sealing effect and longer operation life. Such piston ring consists of two individual single piece type rings placed one above the other, but with each open joint shifted each other. (Double type) Piston Piston ring (Double type)...

SUCTION VALVE, DISCHARGE VALVE Valve washer Valve washer Spring seat Valve seat Parallel pin Lift washer Plate spring Valve plate Damper plate Lift washer Plate spring Valve plate Valve seat Spring seat Valve bolt Valve bolt Suction valve Discharge valve • xcellent anti-corrosion and anti-erosion features, as well as reliability for long-term E continuous operation are absolute requisite for suction and discharge valves. Larger sized valves are of guideless type, because of better hydrodynamical performance. Maintenance is made by spare parts that are common to both suction and discharge...
