Operating temperature: 

  • 35 – 113°F (max. 149°F)1    
  • (1.5 - 45°C (max 65°C))

Operating media: 

  • Condensate (air, water, oil)
  • Non-aggressive
  • Not suitable for emulsion

(1) Max. operating temperature is 65°C, but when temperature is over 45°C, performance may decrease.

 

 

MAINTENANCE

It is recommended, that you do a test once per week to evaluate water quality (residual oil content). Instructions are attached in test set. Replace filter elements when oil content in water becomes too high or at least every twelve months. Before installing new filter elements, interior of the device must be clean.

SERVICE INTERVAL

  • When the first of the following parameters appears:
  • 4000 operating hours of compressor*
  • 12 months, regardless of compressor operating hours
  • Oil concentration in the outlet reaches a concentration determined by local directives and laws.

*Max. operating temperature is 65°C, but when temperature is over 45°C, performance may decrease.
