Wood dust collectors and air filtration systems pull wood dust and particles to reduce airborne particles, which keeps workspaces clean and limits particles that can cause a breathing hazard. Wood dust collectors pull saw dust from the point of origin to keep surfaces clean and limit airborne particulates. Filter and collector bags fit dust collectors to hold dust and filter fine particles before returning air to the workspace. Hoses and fittings capture dust at the source and move it to the dust collector. Replacement parts keep systems in good working order. Woodworking air filtration systems remove fine airborne particles to keep air clean and reduce dust from settling on surfaces. Filters for air filtration systems fit air filtration systems to replace dirty or worn components.
