Rotary Scroll Compressors

Northwest Equipment Ltd. is proud to introduce our newest line of innovative Rotary Scroll Compressors by Gardner Denver.

Oil-less compressors have become a standard in industries such as medical, lab/research, biotechnology, pharmaceutical, food
and beverage, and semi-conductor. Oil contamination is extremely detrimental to these processes. Pure air quality demands are rapidly growing with new regulations and laws regarding oil contamination throughout multiple industries and applications. Gardner Denver has designed the EnviroAire scroll compressor specifically for these applications that require 100% OIL-FREE AIR, including NFPA & CSA code compliant multiplex systems

Industrial & Laboratory Applications

Gardner Denver designed the EnviroAire Scroll compressor system to meet industrial and laboratory requirements for contaminant free, oil-free, clean air applications. Compressors range from
3–10 HP in simplex through quadraplex designs with optional remote receiver, or available as tank mounted with optional integrated dryer. The EnviroAire modular system creates a clean, simple and serviceable layout, maximizing our ability to meet specific application requirements.

Scroll Compression Explained

  • An orbiting (rotating) scroll and fixed scroll housing are mated to create the compression chambers
  • The continual movement of the orbiting scroll moves atmospheric
    air from the intake toward the center, compressing the air into progressively smaller areas
  • The compressed air is directed to the center discharge port of the compressor
  • Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge
