Project Description

Fixed Speed Oil-Less Scroll Air Compressor

EnviroAire S Series 2.2-7.5kW (3-10HP) 

The EnviroAire S products are fixed speed, single stage, 100% oil less compressors from 3 – 10 HP (per pump). Scroll packages have been designed specifically for industrial, laboratory, and medical applications in a variety of configurations. The EnviroAire S Medical scroll systems meet current CSA standards, are NFPA 99 code compliant, and are offered in several designated flow designs.

Oil-free rotary scroll technology (4 to 15kW)

Why oil-free? Don’t compromise on quality

The EnviroAire S Series from Gardner Denver sets the standards for air purity. These oil-free scroll compressors are ISO 8573-1 CLASS O compliant. Offering not only 100% oil-free air but also improved energy efficiency, these compressors are made to meet the precise needs of a diverse range of industries.

EnviroAire S: Superior Compressor Package

Gardner Denver designed the EnviroAire scroll compressor package to meet the strict requirements for contaminant free, oil-free, clean air applications. The scroll compressor range starts with Simplex units at 4, 6 and 8 kW and the Duplex units with 7, 11 and 15 kW. The compressor design features a very clean, simple and serviceable layout.

Scroll Compressor Features & Benefits

  • Low Vibration
  • Compact Footprint
  • Less Moving Parts
  • High Efficiency

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 centre, compressing the air into progressively smaller areas
  • The compressed air is directed to the centre discharge port of the compressor
  • Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge
