Dust extraction systems refer to systems designed to remove dust and other airborne particles from the work environment in industries such as construction, woodworking, and manufacturing. These systems help to ensure that the air workers breathe is clean and safe, reducing the risk of respiratory health problems. They also help protect equipment and reduce the risk of fires and explosions. There are different types of dust extraction systems, including portable units, central systems, and large units designed for industrial applications. The choice of system will depend on the size of the facility and the nature of the work being performed.
