Retain instructions for future 150 Production Drive Harrison, OH 45030 USAD escriptionThe Powerex scroll medical air packageis designed to provide medicalbreathing air for hospital and medicalinstitutes. This system meets NFPA 99requirements for Level 1 breathing Scroll Air CompressorThe Powerex Oilless Rotary Scroll AirCompressor has advanced scrollcompressor technology through thedevelopment of a completely oillessunit. The Powerex Scroll Compressor offers adynamically balanced air end whichinsures vibration-free operation.

2 Therotary design permits a continuous100% duty cycle. No oil separation, oilfiltration, or inlet valves are requiredon the Powerex Scroll air TANKThe ASME, National Board registeredvertical air receiver is provided in sizesfrom 80 to 200 gallons. Each receiver israted at 200 PSIG working are provided with sight glassand moisture drain (manual or auto-matic).CONTROL PANELThe NEMA 12 control panel is providedin all multiplex configurations andmeets NFPA 99 requirements formedical air. Primary voltage isprotected by fusing or circuit transformer power is 110 voltsand protected by secondary switches/transducer control/sthe compressors on and off cycle andsignal lag Compressor (s) to come on ifair demand increases. A lag / lagpressure switch or transducer signals alight and audible alarm warning of areserve Compressor in use conditionwhich is factory set at 85 PSIG.

3 Anacknowledge button is provided forstart condition and maintenance. Theadjustable timer alternator or the PLCcycles each Compressor so equal runtime is maintained. This alternator isScroll Medical Air Packagefactory set to alternate thecompressors every 10 minutes. Theexterior of the control panel isprovided with a main through doordisconnect, on/off/ auto switches, runlights, power on lights, runhourmeters, reserve-pump-in-use light,high temperature light, overload light,horn with acknowledge button andreset button for high temperaturecondition. This control panel is POINT MONITORThe Powerex Dew Point Monitorprovides indication of dew pointtemperature. It is microprocessorcontrolled with user programmableoutput range. Dew Point Monitor isequipped with adjustable alarmcontacts.

4 NEMA panel mount enclosureis protected by a polymer MONOXIDEMONITOR/ALARMThe carbon monoxide monitorprovides warning to the user byalarming and metering the presence ofcarbon monoxide. The monitor isprovided in a NEMA 12 enclosure. Inaddition to audio/visual alarm, themeter displays the concentration of COin the compressed air. The meteroperates from a 110 VAC supply. Alarmpoints are set at 10 PPM (low) and 20 PPM (high).IN551301AV 10/06 PURE AIR TECHNOLOGYAIR COOLED AFTERCOOLERA ftercoolers are sized to provide anapproach of 20 F. Each are constructedof copper tubing for DRYER DESICCANTP owerex scroll medical air packagesinclude desiccant dryer systems. The Powerex Desiccant Drying Systemprovides air at less than 32 F dew pointat 100 PSIG. Each system is connectedwith bypass capability.

5 This system consists of two completelyseparate desiccant dryers. One is acomplete backup of the other. Each ofthe desiccant dryers is a dual towersystem. While one tower is on lineremoving the moisture from the airstream, the other is depressurized,reactivated using a dry purge air flow,and then repressurized for the nextcycle. The purge saving feature on oursystem will suspend the purge cycleuntil the dew point detected by ourhygrometer reaches -10 FILTER SYSTEMThe medical filter system consists of aduplex series of filters and pressureregulators. Air enters the system and isdirected to either bank of filters/dryercontrolled by a ball valve. The firststage filter remove solids and liquidparticles.

The third and final after filteris carbon activated to removeunpleasant odors. Maximum operatingtemperature is 125 F and maximumpressure is 150 DRAIN VALVEAn automatic electric condensate drainvalve is standard on all medical scrollsystems. This valve removes liquid thatcollects in the tank during normalcompressor operation. The electricdrain valve has two built in timers. Thefirst determines the amount of timethat the valve is closed and the seconddetermines how long the valve staysopen. These timers are field adjustableand should be set to insure water doesnot build up in the tank and tominimize air loss.
