AirSep Corporation2.0Safety2.1GeneralOxygen, the most abundant of the elements, makes up approximately 50percent of the earth’s crust. In its free state, it forms about one-fifth of ourair by volume. Although oxygen is classified as a non-flammable gas, itsupports combustion. As an active element, it combines directly orindirectly with all elements except the rare gases. It is an invisible gas thatis colorless, odorless, and tasteless.To ensure your safety, thoroughly read and familiarize yourself with thissection of the manual. AirSep Corporation strongly recommends that youreview this section periodically.2.2Potential HazardsBefore you attempt to install, operate or repair the oxygen generator, readand thoroughly understand this manual. Improper operation can result insevere bodily injury, damage to the unit, or poor performance.Oxygen vigorously accelerates the burning ofcombustible materials. In an oxygen-enrichedatmosphere, many materials that do not burn innormal air require only a slight spark or moderate heatto set them aflame.To avoid fire or an explosion, keep gasoline,kerosene, oil, grease, cotton fibers, paint, and anyother combustible material away from any part of theoxygen generator.Do not smoke or use an open flame near the oxygengenerator.Post “NO SMOKING OR OPEN FLAMES” signs in thearea where the oxygen generator is located. AirSepCorporation STRONGLY recommends that onlyindividuals trained and experienced in the safe handlingof oxygen operate this unit.Topaz/Topaz Plus Instruction Manual2-1
AirSep CorporationTake extreme care to keep all oxygen piping andvessels clean. To avoid fire or an explosion, oxygenclean all surfaces that can come in contact withoxygen. Check all oxygen fittings/joints for leaks withan oxygen-compatible leak-detecting solution.Electrical shock hazard. The interior of the oxygengenerator contains electrical parts that can producean electrical hazard if not handled properly.Connect the oxygen generator power cord to aproperly grounded wall outlet on a circuit that cannotbe accidentally turned off. Do not use extensioncords.To prevent fire or electrical shock, locate the oxygengenerator indoors away from rain or any other type ofmoisture.2.3Safety PublicationsThis section is not a complete summary of required safety procedures.Review the following publications for additional information on the safehandling of oxygen:2-2 “Standard for Bulk Oxygen Systems at Consumer Sites;” NFPANo. 50; National Fire Protection Association; 1 BatterymarchPark; P.O.

AirSep Corporation3.0System Description3.1GeneralThe AirSep Corporation PSA Oxygen Generator is a self-contained unitthat uses Pressure Swing Adsorption (PSA) technology to produceoxygen on site. The PSA process extracts oxygen from ambient air todeliver product oxygen continuously to an application that requires feedoxygen.The oxygen generator uses compressed air from its internal aircompressor as a feed gas to produce the product oxygen. Ambient airenters the air intake, passes through a gross particle filter to remove largeairborne particulate matter, then flows into the internal air compressor.The air compressor pressurizes the feed air and delivers the feed air to aheat exchanger for cooling. The cooled, pressurized air then enters oneof the adsorber vessels.The oxygen generator uses in its adsorber vessels an inert ceramicmaterial called molecular sieve to separate compressed air into oxygenand other gases. The unique properties of molecular sieve allow it toattract, or adsorb, nitrogen physically from air under pressure. This allowsoxygen to exit the adsorbers as a product gas and flow into a mixing tank,which maintains stable flow and purity of the product oxygen. The productoxygen flows from the mixing tank through a pressure regulator thatallows the delivery pressure to be set as required for your application.Finally, the product oxygen flows through a flowmeter, which allows you toset the flow rate required for your application.While one adsorber produces oxygen, the other depressurizes to exhaustthe waste gases it adsorbed (collected) during the oxygen productioncycle. The entire oxygen generating process is completely regenerative,which makes it both reliable and virtually maintenance-free. Themolecular sieve does not normally require replacement when maintainedand used according to this instruction manual.Refer to the Appendix A of this instruction manual for a detailed flowdiagram, an electrical schematic, and specifications for the oxygengenerator.Topaz/Topaz Plus Instruction Manual3-1
