When applied at rated capacity and specified operating conditions as shown in Table III and properly maintained, 8DM Series purifiers supply air that meets OSHA, Canadian Standards Association (CSA) and Compressed Gas Association (CGA) standards for compressed breathing air quality, as well as National Fire Protection Association (NFPA) standards for medical air quality. Refer to Table 1 for the maximum allowable carbon monoxide concentration levels at the purifier inlet. Air entering the purifier must not be oxygen deficient. 8DM Series purifiers will not increase the oxygen content of purifier inlet air. WARNING To ensure continuing good...
