Title: micron sizes
Post by: Kyle on December 31, 2008, 04:07:06 pm

Lets start with some fundamentals before everyone jumps the gun, I have a little info I will share with ya all..... About Micron Sizes and Particle Filtration
 
 
    Filtration is the process of forcing a liquid or gas through a porous medium to remove solid particles. The particles are measured or classified in microns. One micron equals 0.0000394".   Absolute-rated filter cartridges will retain at least 99% of particles of a particular micron size.
