Oil-Free Scroll Air Compressors 5.5kW

Yes, rotary scroll compressors like the Gardner Denver EnviroAire Series are inherently oil-free by design. The scroll compression mechanism does not require lubrication oil within the compression chamber, making them ideal for applications demanding ISO 8573-1 CLASS 0 air quality. This eliminates the risk of oil contamination in sensitive environments such as medical facilities, laboratories, and food production.

Oil-less scroll compressors are engineered for long service life when properly maintained. Gardner Denver's EnviroAire Series is built with a compact design featuring fewer moving parts, reducing wear and extending operational life. Tip seals are the primary wear component and are replaceable at scheduled intervals. With routine maintenance and genuine OEM parts, these units deliver reliable continuous operation across demanding duty cycles.

The Gardner Denver EnviroAire S & ES Series is rated for 100% continuous duty cycle operation. This means the compressor can run without interruption, making it ideal for medical, laboratory, and industrial environments where a consistent, uninterrupted supply of clean compressed air is critical to operations and safety.

The EnviroAire S & ES Series delivers a flow range of 8–126 CFM at 116 PSI, with pressure capabilities between 116–140 PSIG. The power range spans 3–10 HP, making these compressors suitable for a variety of small to medium-scale medical, laboratory, and industrial applications requiring pure, oil-free compressed air.

Yes. The Gardner Denver EnviroAire S & ES Series is fully compliant with NFPA 99 for medical air applications and meets CSA code requirements. It also carries ISO 8573-1 CLASS 0 certification, the highest standard for oil-free air quality. These certifications make it a trusted choice for hospitals, dental facilities, sterilizers, and other critical healthcare environments.

Oil-free scroll compressors are ideal for industries where air purity is non-negotiable. Key sectors include medical and dental facilities, pharmaceutical and biotechnology, food and beverage production, semiconductor manufacturing, laboratory and quality control, and general industrial applications such as paint booths and HVAC climate control — any environment where oil contamination would compromise product quality or safety.
