PARTICLE SIZE EVALUATION

Small enough to cost you big money if your filter bags aren't containing that size dust particle. ECC Laboratories employ the largest state-of-the-art equipment measuring particles by volume, weight, surface area and actual population counts into 256 different micron sizes down to 0.2 microns. Graphs both accumulative and differentials are computed. Did you know that 1,000,000 particles at 0.5 Micron equals the same weight as just 1 particle at 50 Micron? Fine particles at 0.2 to 1.0 Micron can leak through and cause emission problems, and severe ID and fan damage. Particles not fully penetrating can lead to bag binding and high pressure differentials. Filtration of airbourne particles by a filter fabric employs the science of contact. The particle must make contact with a target. The initial contact positions are the fibers as a particle contacts a fiber and is collected, it now becomes a target. This process continues with increased targets and increased efficiency. Particle size ranges from 0.2 to 1.0 Micron are the least influenced for contact and are the highest degree of difficulty in filter fabric collection.
