Circular Letter M45/01 Post Primary Building Unit, Tullamore, Co. Offaly. Wood Dust Extraction Systems in Second Level Schools TO: MANAGEMENT AUTHORITIES OF SECOND LEVEL SCHOOLS 1. Background The Department of Education and Science has investigated ways of controlling air borne dust in specialist rooms in second level schools. Wood Dust Particle Sizes The picture below shows the sizes involved. As a point of reference I will use a human hair which is typically 70 microns ( mm) in diameter. Wood dust covers the range from millimetres down to less than microns. The labels PM in the diagram refer to Particulate Matter, so Wood Dust Extraction Systems 64 PM 10 means particles smaller than 10 File Size: KB. Wood dust becomes a potential health problem when wood particles from processes such as sanding and cutting become airborne. Breathing these particles Wood Dust Extraction Systems 01 may cause allergic respiratory symptoms, mucosal and non-allergic respiratory symptoms, and cancer. The extent of Woodwork Dust Extraction Java these hazards and the associated wood types have not been clearly established.

Because the bulk of debris never reaches the collector’s small collection/filter bag, an affordable 4" portable collector, such as the 1-hp unit shown in the opening photo, operates more efficiently than it would without the www.- r, adding a separator can reduce a collector or vacuum’s overall airflow, so keep flex hose lengths as short as possible to minimize this. Dust Extractors, SCHEPPACH, Woodworking; HD12 Dust Extraction Systems For Woodwork 30 Dust Exctractor £ Inc VAT; Anyone working wood machinery without a dust extractor is not only creating a great deal of mess but is also damaging his health. The scheppach hd12 is the solution to both these problems providing sufficient air flow to deal with all dust problems.
