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. Because...

•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.
