    SECTION 2 SYSTEM DYNAMICS SYSTEM DYNAMICS SYSTEM DYNAMICS Description & Applica- tion The Quincy Compressor QR-25 Series consists of heavy duty industrial, belt driven, single or two stage compressors. Single stage compressors are capable of delivering up to 100 PSIG con- tinuously.

  • Page 9: Principles Of Lubrication Systems

    Fan blades of the compressor sheave force ambient air across fins of the cylinder head(s), and intercooler fins of two stage compressors, to cool the compressor. QR-25 series compressors are normally set up at the factory with a sheave that turns in a counterclockwise rotation. For special applications, clockwise rotation compressor sheaves are available as optional equipment on some models.
