The compressor assembly is designedto maximize part-load system air systems are dynamic in nature. TheV Series is intended to supplement your base-loadcompressor or Compressors to satisfy varying com-pressed air demands in the most efficient way.

2 OurV Series combines Quincy Northwest reliable full-load performance with efficient part-load variablespeed controlling compressor output to match systemdemand, substantial energy savings can beachieved. Compressed air energy savings flowdirectly to your bottom addition, the adjustable Speed drive limits in-rushcurrent at start up, reducing your peak demand,providing more energy cost chart below illustrates the energy savings of ourvariable Speed QNW V Series Assembly Offers: State of the art energyefficient controls. compressor outputmatches system demand. Constant pressureeliminates large pressure differentials.

3 Adjustable Speed drivelimits starting current in-rush. Direct Drive, non-gearedair end. High efficiency rotordesign results in maximumair flow using minimalhorsepower. compressor controls that offer the flexibility to efficiently tailor com-pressor operation to specific site conditions and requirements. Full factory-monitoredmaintenance program. Triplex bearings aredesigned to ensure long superior three bearingarrangement consistentlyprovides longer life thancompetitive machines. The V Series shaft seal isa triple-lip type design. Thisdesign is more reliable thana mechanical seal. Rogers CLS46 syntheticcompressor lubricant pro-vides extended lubricantlife.
