Dust Collectors are technologies used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
Dust can be separated into two categories: combustible and non-combustible. Non-combustible dust, as its name implies, will not under predictable conditions ignite, burn, release flammable gases, or support combustion when subjected to fire or heat.
