The characteristics of any industrial dust influence the design of the capture and filtration system. Woodworking dusts vary with the process concerned i.e. product being made, tool/operation, and type of wood. For example dust generated in sanding operations is comprised of particles generally below 10 microns in size whilst at the other end of the spectrum planning can create “curls” up to several inches long.Tool sharpness affects shredding and tearing of the material often producing particles of larger size. Typically working with softwoods produces larger particle sizes than hardwoods.The dominant characteristics of wood dust are the variation in size and the bulk volume of dust that is created. Woodworking dust control requires effective capture at source and efficient filtration. A typical dust control system is composed of four components: a hood/hoods to confine dust at its source, duct work to convey the captured material, a fan to maintain suction in the hoods and ducts, and a filter unit to separate the dust from the exhaust air and deposit it in a storage container. The design and maintenance of the system must take into account the significant risk of fire and dust explosion present in this application.
