After reading the issue of Wood magazine regarding dust collectors I decided I needed to do something to make my environment healthier. The Crafstman dust collector I had purchased came with 30 micron filter bags. I ordered replacement bags from American Fabric Filter. The new upper bag is 72 inches tall and will filter down to 1 micron. I ordered 4 heavy plastic lower bags, 5 or 6 mil thick, can’t remember.
I first ran the machine after replacing just the upper bag. It filters so good that dust started coming out of the lower bag like mad. I immediately shut down the machine and replaced the lower bag with one of the plastic bags.
I am completely amazed at the difference in my dust collector after the upgrade, it’s like a whole new machine. I have no way to scientifically prove this but I can a vast improvement in the cubic feet per minute of air being sucked through the hose.
I’ve never liked the based of the machine. The sheet metal is far too thin. I’m also not happy about my improvised upper bag hanger. This weekend I hope to make a better base out of MDF, find some way to raise the section where the bags attach and create a better upper bag holder.
