      SanFam products regularly undergo stringent quality control and only  very seldom the malfunctioning 
      of  the compressor has to be ascribed to the  filter itself.  
      Here below are listed some of the most common causes which may lead to an improper functioning of
      the machine.

   Ⅰ . Precautions for installation 

     1 . Place the gaskets properly, antistatic measurements should be fitted and the oil-proof gaskets
          need to work normally at the high temperature of 120℃.
   
     2 . Separator installed erectly with compressed air flows from outside to  inside, the scavenge tube 
          should be long enough to be straight laid inside the  separator and reach to the concavity of the
          bottoms.
    	  
     3 . Use high quality lubricant. Don’t mix any impurities into the lubricant  system and the lubricant
          should be replaced completely at a regular period.
    	
     4 . Spin on air/oil separator installed erectly, the scavenge tube  should  be laid down to the bottom
          of the separator.     

  Ⅱ . Pressure drop rises too fast


          The pressure drop is mainly  caused by the solid particles in compressed air,  which intercepted by
          the  media of separator and detained on the media.
  
     1 . The air filter and oil filter used in compressors have lifespan and need  to be replaced  regularly.
          Don’t use the air filter and oil filter with low  quality.
 
     2 . Higher compressor working temperature or low quality lubricant relates  to age and oxidate  the oil
          and forms oil particles, which block and pollute   the separator, and the pressure drop rises.
         
     3 . Regularly drain the tank, or the separator may be rusted.     

   Ⅲ. Excessive use of oil
    	 
     1 . Blocked or malfunctioning of scavenge tube causes oil accumulated in the  separator and the oil is
          taken out by compressed air with considerable amount.

     2 . Incorrect oil level in tank. Oil over filling alters the pre-separation  process and  increases the
          amount of oil in the air/oil mist thereby the  separation efficiency is reduced.
    
     3 . Unreasonable design of oil tank. Short diameter of oil tank or  inefficient mechanical separation
          structure.
    	   
     4 . The separator is not suitable for the machine, which results an  inefficient separation.
    	  
     5 . Gaskets are out of place or use of unsuitable or used gaskets, which can  cause the oil leak. 
      
     6 . Compressor working at lower pressure increases the flow rate and reduces  the separation 
          efficiency.

     7 . Compressor working at higher temperature speeds up the evaporation of  oil and increases the 
          thickness of air/oil mist in separator.

     8 . The separator has reached the end of its lifespan or has worked in  arduous conditions and is 
          not replaced.
