    1.2 About Compressor 1.2.1 General W31 Series compressors are three stage, reciprocating type, air cooled and splash lubricated compressors. Working pressure of these compressors, depending on valves and heads, can be between 10 bar (1500 psi) and 350 bar (5000 psi).
  • Page 15 (Please see Maintenance Table.) W31 Series compressors are equipped with stainless valves at each stage that are designed to maintain the airflow without any loss of pressure. They are easy to maintain and replace. The maintenance of valves are especially important as they are the main parts in proper and problem-free working of compressors.

Water Separators: They remove the water condensate from the compressed air occurred in stages under pressure. There are two water separators on W31 Series; 2 and 3 Stgs. Purifier: This is the filtration system that purifies the compressed air to produce breathing air comply with breathing air quality standards.

    It does not let the air go unless the inlet pressure of the purifier reaches a certain value (150 Bar). At this pressure the filtration is much more efficient than any pressure. CONSULT THE NEAREST ALKIN DEALER OR ALKIN FOR REPLACEMENT OR MAINTENANCE. Check Valve: It does not let the compressed air inside the purifier goes back to the stages and protects the compressor to run under back pressure.
