Air capacity refers to dust removal equipment to purify gas volume per unit of time. Unit of cubic meters per hour (m/h) or cubic meters per hour (Nm/h). In bag design is one of the most important factors.
Designed according to the wind or when choosing a bag, generally cannot run filter in the set volume, otherwise, prone to clogging of the filter bag, reduced life expectancy, increased pressure loss, the dust removal efficiency to reduce but also air volume selected cannot be too big, the increased investment in equipment and covers an area of, and a waste of resources, saving energy. Choice of reasonable handling of air flow is often the technology and experience to decide.
