About Dust Extraction

Dust extraction systems provide a pleasanter and cleaner work space and, more importantly, a healthier one. According to the statutory Control of Substances Hazardous to Health or COSHH regulations, employers must protect their workforce from the problems which arise from the presence of airborne particles. Solid particles with a diameter of less than 500 micrometres can be inhaled, leading to health problems, especially for those with respiratory issues. For example, the inhalation of wood dust can lead to bronchitis and emphysema. Additionally, a dusty atmosphere can be a source of ignition and explosion, as outlined in the Dangerous Substances and Explosive Atmospheres regulations. Even those who work alone are well advised to ensure that their environment is dust free. Smaller dust collection systems consist of a single stage vacuum unit which draws the particles out of the atmosphere and deposits the material in a collector before filtering and recirculating the air. Larger systems are generally two stage and separate large and fine particles before passing the air through filtration units. A wide range of items designed to deal with varying degrees of dust extraction are available, from manual sanding blocks with dust extraction facilities to entire dust extraction units, both used and new, and large units suitable for industrial use. There are also combination wet and dry vacuums and dust extractors, space conserving wall mounted extractors and portable units. Also offered are accessories and affiliated equipment such as extractor hoods, flexible ducting hoses and elbows, blast gate dampers for controlling airflow and replacement collection bags and cartridges, including those designed for heavy duty use.
