How big are oxygen particles

WebThe D50 number mean that 50% of the particles that were measures are larger than this number, and 50% were smaller. So, if a particle when measured you may have a D50 of, say, 4 microns. (Usually written as D50= 4 microns.) This means half the particles were over 4 and half were under. Webestablished for specific oxygen systems or what design factors may drive these requirements. Particles are known to have the potential to ignite within oxygen systems and must be limited to prevent fires. Particulate contamination may also pose risks to the performance of oxygen systems that are unrelated to ignition hazards.
