カタログの1ページ目を開くNotes on Using this Pamphlet: This pamphlet is presented to assist an engineer or medical facility contemplating the installation of an Instrument Air system as countenanced under the NFPA 99 Healthcare Facilities standard, 2005 version. Users are cautioned that this pamphlet is intended to be used in conjuction with the standard, which should be obtained from: National Fire Protection Association Users are cautioned to read the pamphlet and the standard carefully, and are encouraged to use the information herein as suited to the conditions of their project, where such modification does not...
カタログの3ページ目を開くThe purpose and the history of Medical Support gases. Why consider instrument air in lieu of Nitrogen? How to estimate the economics of an instrument air What is an instrument air system and what are the requirements as found in the standard. Design issues with instrument air pipelines. Converting nitrogen pipelines to run instrument air. The paper reviews the background of the most recent addition to NFPA's piped gas systems and discusses when the use of Instrument Air might be appropriate. Also reviewed are the rules for the application. Design guidance is provided to allow a system to be...

In most of the world, compressed air never lefttheO.R. In the United Kingdom for instance, it is common to install a "7 bar" or "13 bar" surgical air system specifically for driving tools alongside the "4 bar" medical air for treating There is a vestigial holdover from the use of compressed air for surgical tools in use in North America even today. Surgical tool hoses are still often fitted with a quick connect fitting on the end...
カタログの5ページ目を開くcleaning and sterilization. Medical Air cannot be used for this purpose, so the only acceptable alternative has been to install nitrogen. Aside from the cost of nitrogen, this use implies releasing quantities of Nitrogen into the room. Although Nitrogen is itself non-toxic, the release of too much nitrogen will dilute or displace the oxygen in the air and can cause asphyxiation. Nitrogen is therefore not ideal for use in workspace applications such as this, whereas Instrument Air is very suitable. Applications for Instrument Air are discussed in NFPA 99 5.1.3.8.2.1: "Instrument Air shall be...
カタログの6ページ目を開くPrimary Supply Secondary Supply Quality Control Charcoal Odor/Taste Removal Detail 5 : Instrument Air Source System configurations (Per NFPA 99 Pressure High The particular aspects unique to Instrument Air can be 1. Compressor Type: A compressor used for Instrument Air may be of any type which can produce a pressure greater than 200 psig. Instrument Air compressors do not have to be oilless or oilfree (unlike compressors for Medical Air) but may include lubricated types. This is because the high pressure required makes lubrication inescapable, and since Instrument Air is not breathed by the...

カタログの8ページ目を開くexpensive option for installing smaller systems, and yet does not greatly reduce the operational safety of the system overall if properly alarmed. Where this cylinder secondary is applied, there is a special allowance in the standard for placing the cylinder header with the Instrument Air compressor itself. This is an exception to the general rule that cylinders are not permitted to be in the same room with compressors or pumps. It applies only to the active header used to back upan Instrument Air compressor. There is no exception for loose cylinders, even if those are intended for the...
カタログの9ページ目を開く7. Instrument Air has it's own color coding and labelling (see Detail 7.1 ). The color for Instrument Air is a red ground with white lettering, and the abbreviation is "Instrument Air". Standard pressure is 160-185 psig through the pipeline, and the nonstandard pressure rules will apply for Instrument Air systems operated at different pressures (see 8. Alarm requirements for Instrument Air are similar in most respects to those for any medical gas system (local, master and area alarms are all required). However, the unique configurations permitted for the source do imply some specific alarm...
