The Fundamentals of a Downdraft Table
The air you breathe you is not pure. Millions of microscopic particles mix in with oxygen, and most of these are harmless. If they were pure, they would smell different. When your neighbor is cooking meat on BBQ, for instance, you can tell because you can smell it in the air.
The same goes in the workplace. You can smell wood or metal if you work around them. These are harmless unless you do tasks, like cutting and sanding, that turns them into tiny bits. Inhaling them isn’t going to harm you yet unless you’re exposure to them for too long.
Fortunately, there’s a way to save you and your workers from harm. Dualdraw.com noted that using downdraft tables help reduce the amount of airborne wood or metal dust in the air. Here’s what you need to know about them:
A downdraft table is a filter system that collects dust and other particles in the air, while working with wood or metal. If you have seen someone do welding or sanding, you will see sparks flying and dust clouds forming. These sparks and dust clouds contain tiny bits of wood and metal that is so small you can breathe them in. These can irritate the eyes, skin, throat, and most especially the lungs. Downdraft tables suck and keep particles as small as 0.5 microns before they can do any harm.
Downdraft tables are either wet or dry. A wet downdraft table is suitable for metalworking, and uses water or any other liquid to collect metal dust. It has impellers to draw the dust to the filter. A dry downdraft table, on the other hand, is for woodworking and uses a vacuum to draw dust, fumes, and smoke. It also uses a filter to catch particles and clean the air.
Downdraft tables come in all shapes and sizes, and you can make one or order a customized type for your needs. The size of the unit depends on how much dust it has to collect. If you’re still lost, you can contact a downdraft table manufacturer to help you figure out what size you need.
Downdraft tables are typically for woodworking and metalworking, but it can also be useful for preparing chemicals and explosives. The thing is to remember that it collects dust and harmful particles, so it is appropriate for anything small that can cause harm.
