A common use for flexible ducting of all sizes is the transporting of what are known as “abrasives.” Abrasives are solid materials (as opposed to fumes or liquids), and can theoretically come from any source. Due to the obvious prevalence of abrasives in almost all areas of industry, it should come as no surprise that duct hoses designed to deal with abrasives are among the most common type of flexible ductwork in existence.
Some of the most common types of abrasives that would typically be transported via a duct hose are leaves, wood chips, sawdust, aluminum shavings, and dust. Wood dust is a very fine particulate that can be harmful to human health, especially when inhaled. This is why wood dust collection is a common need for both residential and commercial areas. From professional carpenters to hobbyist woodworkers, wood dust collection is essential in all areas where the sawing, shaping, and detailing of wood are present.
Wood dust becomes a potential health problem when wood particles from processes such as sanding and cutting become airborne. Breathing these particles may cause allergic respiratory symptoms, mucosal and non-allergic respiratory symptoms, and cancer. Wood dust is also flammable which is another reason it is collected when produced. Wood dust is considered to be explosive if ignition of part of a cloud of wood dust results in the propagation of flame. The vigor of flame propagation will vary from dust to dust and not all flammable dusts are equally explosive. The collection of wood dust in industrial settings is of utmost importance!
