The U.S. Environmental Protection Agency (EPA) in their Epa PM2.5 NAAQS Implementation says fine dust particles sized 2.5-microns and smaller pose significant long term risks 5/15/2011 Bob Molby 25 The Health Hazard • The accumulation of fine wood dust in our airways and lungs creates long term problems similar to asbestos and fiberglass inhalation • The medical research is clear there is no safe level of wood dust exposure because every fine wood dust exposure creates some measurable damage and some of this damage becomes permanent. The amount of damage depends upon our general health, how much we take in and for how long. • From ClearVue Website 5/15/2011 Bob Molby 26 How • • • • Broom and shovel Shop Vac Bag system I chose a Cyclone Collector 5/15/2011 Bob Molby 27 My Cyclone Collector First: Shop Layout 5/15/2011 Bob Molby 28 Shop Layout STORE STORE RS LATHE BS GR PL DP TS J 5/15/2011 Bob Molby 29 My Cyclone Collector First: Shop Layout Second: Dust collector design 5/15/2011 Bob Molby 30 Dust Collector Design • Requirements – Collect the “dust” 5/15/2011 Bob Molby 31 Dust Collector Design • Requirements – Collect the “dust” – Central system 5/15/2011 Bob Molby 32 Dust Collector Design • Requirements – Collect the “dust” – Central system – DIY compatible 5/15/2011 Bob Molby 33 Dust Collector Design • Requirements – Collect the “dust” – Central system – DIY compatible 5/15/2011 Bob Molby 34 Dust Collector Design • Requirements • Cyclone- Which one? – Onieda, Grizzly, Penn State or ClearVue 5/15/2011 Bob Molby 35 Dust Collector Design • Requirements • Cyclone- Which one?

This is an article by Dr Rod Cole that discusses the myths surrounding static electricity and PVC pipe. • From my research: – Dust transport in PVC does generate static electricity and can cause an irritating shock 5/15/2011 Bob Molby 51 Static electricity • First, if you like to read, go here: http://mywebpages.comcast.net/rodec/wood working/articles/DC_myths.html. This is an article by Dr Rod Cole that discusses the myths surrounding static electricity and PVC pipe. • From my research: – Dust transport in PVC does generate static electricity and can cause an irritating shock – There is not enough energy to ignite the dust 5/15/2011 Bob Molby 52 Static electricity • First, if you like to read, go here: http://mywebpages.comcast.net/rodec/woodwo rking/articles/DC_myths.html. This is an article by Dr Rod Cole that discusses the myths surrounding static electricity and PVC pipe. • From my research: – Dust transport in PVC does generate static electricity and can cause an irritating shock – There is not enough energy to ignite the dust – The NFPA code requirement is for air flow of 1500 CFM 5/15/2011 Bob Molby 53 My Dust Collector! • 6” jointer, with 4” flex tubing to 6” main line. • Should enlarge cavity where tubing is connected. 5/15/2011 Bob Molby 54 My Dust Collector!
