 J-Series Piston Compressor

SEAH INDUSRTRY



   

 

 

   


               SEAH INDUSTRY has been producing and providing J-series compressor for last 40 years.

 

               Being well recognized worldwide for its durability and reliability, J-series reciprocating compressor is

               specially designed to endure a heavy duty under the 24 hour continuous operation.

 

               They are 100% oil free and their performance and quality are guaranteed until the end of their service life

               In addition, they are two-stage model and water cooling type.

 

                

     

 

 

              

                  1.  Aerodynamic appearance 
                  2. Special designed water jacket with the

                      maximized cooling capacity             

                  3. Conical piston with the equal distribution of the

                       pressure he maximized effiency

                  4. Divided packing ring with a self-care function 
                  5. Concentric shaped valve with the mximization

                       of the delively surface               
                  6. Separate cross head guide easily inter

                      changeable at field

                  7. Divided piston ring with 12 times longer life and 

                      high efficency maintaining 
                  8. Minimization of repair/maintenance cost in case of 

                      possessing more than two types of SeAH made 

                      compressors with the standardization and the

                      interchangeability of all parts of the compressor

                      which ensure 100% oil free for their whole life

                  9. All kinds of our spare parts produced by JOY-design 

                      can be utilized everywhere in the world.


                     Only SEAH INDUSTRY can guarantee the quality of the compressors produced under the 140years JOY design

                   despite lots of imitation of domestic and overseas companies.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  

 

     


Piston rod


     Oil fee piston rod is made of chrome coated alloy steel strong enough 

     to be used for aircarft and piston is designed as conical type to be 

     fitted for the shape of its cylinder head.

Gapless ring   

         

     Self-centering gapless compression ring of JOY designed for keeping

     the nominal size constant irrespective of abrasion operates under the

     perfectly closed position by removing any gap between cylinder liner

     and ring which is pointed out as a demerit of traditional fing.
     For this reason, maximization of compression efficiency and 

     12 times longer life than other products shall be guaranteed.

 

 Cylinder Liner 

 

     Cylinder and cylinder head made by specialcasting and cylinder 

     liner special centrifugal casting are easy to disassemble, repair 

     and replace. Water jacket inside of cylinder is designed for the

     maximum cooling efficiency. And as oil free liner is coated with

     chrome to avoid any corrosion and extend its life, no corrosion in

     downtime is allowed.
