Classic Collection Efficiency Curve with Filter Collection Mechanisms

Summary[edit]

Description
English: For mechanical filtration using a filter the filter's efficiency is dominated largely by the forces of diffusion, interception, and impaction. The lowest point on the curve represents the particle diameter for which the filter is least efficient.
Русский: Зависимость степени улавливания от размера пылинок механическим фильтром. Эффективность фильтра определяется силами диффузии, прилипания и столкновения. Самая низкая точка кривой представляет отвечает размеру пылинок при котором фильтр наименее эффективен.
