Laboratory air is an air compressor that needs to deliver very clean, very dry air for a laboratory, pharmaceutical or biomedical application. These systems are not regulated by NFPA 99 therefore, both compressors can run simultaneously. Sizing in the chart below is for both compressors running. Laboratory air can deliver pressure higher than a medical air compressor still using the same Scroll technology. As in Medical Air, Scroll Technology is incredibly quiet and requires very little maintenance.
