[FIGURE 1-2 OMITTED]When the magnetic gaspoweredaircompressor bearings are energized, the motor and impellers, which are keyed directly to the magnetic shaft, levitate. Permanent-magnetic bearings do the primary work, while digitally controlled electromagnets provide the fine positioning. Four positioning signals per bearing hold the levitated assembly to a tolerance of 0.00002 in. As the levitated assembly gaspoweredaircompressor moves from the center point, the electromagnets'' intensity is adjusted to correct the position. These adjustments occur 6 million times a minute. The software has been designed to automatically compensate for any out-of-balance condition in the levitated gaspoweredaircompressor assembly.SHUTDOWNS AND POWER FAILURESWhen the compressor is not running, the shaft assembly rests on graphite-lined, radially located touchdown bearings. The magnetic bearings normally position the rotor in the proper location, preventing contact between the rotor gaspoweredaircompressor and other metallic surfaces. If the magnetic bearings fail, the touchdown bearings (also known as backup bearings) are used to prevent a compressor failure.

NITROGEN GENERATORSNitrogen generators use either membrane or pressure-swing-adsorption (PSA) technologies. Membrane generators made by Balston, a division of Parker, produce up to 99.5% pure, commercially sterile nitrogen at dewpoints to -58[degrees]F from compressed air. gaspoweredaircompressor They use proprietary membrane-separation technology to divide air into two streams: one 95 to 99.5% pure nitrogen, the other oxygen-rich with carbon dioxide and other trace gases.Compressed air flows through bundles of individual, hollow fibers made of semipermeable membranes. Each fiber has a perfectly circular cross section and a uniform bore through its center. Because the fibers are so small, a great many can be packed into a limited space, providing enough surface area to produce a relatively high-volume flow of nitrogen.

The use of permanent magnets instead of rotor windings makes the motor smaller and lighter than induction motors. Using magnetic-bearing gaspoweredaircompressor technology, a 75-ton compressor weighs 265 lb--about gaspoweredaircompressor one-fifth the weight of a conventional compressor.A gaspoweredaircompressor variable-speed drive (VSD) is required for the motor to operate. The VSD varies the frequency between 300 and 800 Hz, which provides a compressor-speed range from 18,000 to 48,000 rpm. This avoids a gear set. The VSD is integrated into gaspoweredaircompressor the compressor housing, avoiding long leads and allowing key electronic components to be refrigerant-cooled. The VSD also acts as a soft starter; as a result, the compressor has an extremely low startup in-rush current: less than 2 amps, compared with 500 to 600 amps for a traditional 75-ton, 460-v screw compressor with a cross-the-line starter gaspoweredaircompressor.
