Transcription of Breathing and Medical Air Purification Packages
1 Breathing and Medical Air | Features and BenefitsBreathing and Medical Air Purification PackagesThe need for clean, pure, compressed Breathing airThe ambient air that enters the compressor in a compressed air system can be loaded with impurities such as particles, liquids (oil and water) and harmful gases such as carbon monoxide. During the compression process, this level of contamination may be further increased in the air stream and therefore without suitable treatment can pose severe health risks if it is used for Breathing air in Medical and industrial safeguard the health of users of Breathing and Medical air, regulatory standards have been adopted worldwide to define the quality of Breathing air that is required.
2 The SolutionTo ensure that Breathing air is consistently delivered to a high level of purity from a compressed air system, Walker Filtration has designed a range of Breathing air Packages which comply with international Breathing and Medical air standards. A major feature of the package is the capability to control carbon monoxide, which is one of the most common life threatening Features / BenefitsDesigned to comply with international Breathing and Medical air standardsThis range of Breathing and Medical air Purification Packages conform to international Breathing air standards and the European Pharmacopoeia Medical air solutionA standard range of Breathing air Packages from 42 Nm3/hr (25 SCFM) 297 Nm3/hr (175 SCFM).
3 Larger flow capacities and duplex systems are available upon to installCompact integrated design enables the Breathing air Packages to be installed in confined performanceThe desiccant based purifier utilised within the package is electronically controlled and equipped with a remote alarm monitoring function. In addition, the service status can be monitored using the built-in LED and efficient servicingPureflow desiccant and catalyst purifiers are both cartridge based which enables simple, time efficient replacement when compared to traditional loose filled vessels.
