M Class Dust Extractor Hire Essential for Healthy Air on Site M class dust extraction units are key pieces of equipment when working on site and in workshops, for safely vacuuming the dust produced by power tools such as saws, drills, sanders, wall chasers and more. Inhaling the dust produced when cutting into brickwork, wood and other materials can cause real harm to your health; but with their strong suction rate, power take off capacity and heavy duty filter, these wet/dry dust extraction units make the work area safe from this harmful dust. These lightweight dust extractors feature M-class fine filters for wood, MDF and metal materials and M-class H&S requirements for wood applications. They are capable of extracting 99.9% of dust with limit value for occupational exposure 0.1 mg/m³. They also have an automatic filter cleaning system and a blockage warning, which alerts you if the airflow drops below the minimum required level for effective dust extraction. These dust extraction units have an auto-start feature which works in conjunction with the power tools. This means that when a power tool is plugged into the wet/dry dust extractor, the extractor will turn on when the power tool is operated and turn off slightly after the power tool has finished being operated, to allow for any excess dust to be removed from the hose. M Class dust extractors are the minimum legal requirement set by HSE for use on site. For more information on dust safety, take a look at HSE Guidance on Construction Dust and HSE publication CIS69 on controlling construction dust with on-tool extraction.
