 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. They use proprietary membrane-separation speedaire gas 2 stage air compressor technology to divide air into two gas and 2-stage 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. air each fiber has a perfectly circular cross section and a uniform bore compressor through its center. speedaire gas 2 stage air compressor 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. oxygen, gas and 2-stage water vapor, and other trace gases permeate the membrane fiber and are discharged through air a permeate port. nitrogen compressor stays within speedaire gas 2 stage air compressor the hollow fibers and flows through an outlet port.balston gas psa 2-stage nitrogen air generators compressor produce up to 99.95% pure, compressed nitrogen speedaire at dewpoints to -40[degrees]f from nearly any compressed-air supply. the generators continually transform gas air into nitrogen 2-stage at safe, regulated pressures without air operator attention.psa compressor generators use a combination of filtration and psa speedaire and gas and 2-stage technologies to create nitrogen.compressed air air is prefiltered to remove compressor all contaminants speedaire and gas down 2-stage and air to 0.1 micron. the gas separation process preferentially adsorbs compressor oxygen over speedaire nitrogen using carbon-molecular gas sieve (cms). at high pressures, the cms has a greater affinity for oxygen, carbon dioxide, and water vapor than it does at low 2-stage pressures. by raising air and lowering pressure within the cms bed, all compressor contaminants are speedaire captured and released, leaving the cms unchanged. this process lets nitrogen pass through. depressurizing the cms releases adsorbed oxygen and other contaminant gases to the atmosphere. the gas use of permanent 2-stage magnets instead of rotor windings makes the motor smaller and air lighter than compressor induction speedaire motors. using magnetic-bearing technology, a 75-ton compressor weighs 265 lb--about one-fifth the weight of a conventional gas compressor.a variable-speed drive (vsd) is 2-stage required for the motor to operate. the air vsd varies the frequency between 300 and 800 hz, which provides a compressor-speed compressor range from 18,000 to 48,000 rpm. this avoids a gear set. the vsd is integrated into the compressor housing, avoiding long leads and allowing key electronic components to be refrigerant-cooled. the vsd also acts speedaire as a soft starter; as a gas result, the compressor has an extremely low startup in-rush 2-stage current: air less than 2 amps, compared with 500 to 600 amps compressor for a traditional 75-ton, 460-v screw compressor with a cross-the-line starter.
