The ELGi AB series oil-free compressors offer a highly efficient alternative to conventional oil-free, dry screw two-stage compressors, delivering top-notch 'Class 0' oil-free compressed air. These compressors adopt a unique approach by introducing water into the compression chamber to dissipate the heat generated during compression instead of relying on oil for cooling, as seen in oil-injected screw compressors. As a result, the AB series compressors discharge air free from any microbiological contamination, adhering to the ISO 8573-7 standards. The FDA has approved the ELGi AB series compressors as contaminant-free equipment. Today, these oil-free compressors from the AB series provide essential support to critical and sensitive applications that demand exceptionally high air quality standards and ensure the absence of any mineral oil residue.
