3.1. 

 
 

The intermediate separator (Fig. 9) is mounted after the two first stages of the 2-stage oil-less compressor.  The 

 

separator is designed to remove excess water which results from the cooling down after the compressing process 

 

and thus to provide the next stage with a cleaned medium.  Separation is achieved by means of a baffle (4).  A 

 

sintered metal filter (2) is provided additionally to remove dirt contamination. 

 
3.1.1. CONDENSATE 

DRAIN 

 
 

The condensate has to be drained manually as soon as "max." mark is reached, or after each operation.  

 

Therefore open knurled nut mounted on the lower part of separator housing.  After draining the condensate, 

 

firmly tighten knurled nut. 

 
 

Compressors which are equipped with a condensate drain valve are drained automatically.  Ensure that the 

 

separators are drained every 15 minutes.  At increased humidity, intervals for draining may be shorter. 

 
3.1.2.  INTERMEDIATE SEPARATOR MAINTENANCE 
 
 

Proper operation of individual stages will rely on the intermediate filter being properly serviced. 

 
 

The sintered filter element of the intermediate 

 

separator is to be cleaned approx. every 4,000 

 operating 

hours. 

 
 

-   Remove condensate drain piping from filter. 

 

    Unscrew union nut and remove filter cartridge. 

 
 

-   Remove center screw (1), and separate 

 

    sintered filter element (2). 

 
 

-   To clean filter element, the best method is to 

 

     use hot soapy water and to blow dry with 

 

     compressed air. 

 
 

-   On reinstallation of filter elements take care to 

 

     observe correct order.
