I posted these questions over on the CKD Forums, but thought I would post here also in case I can get some valuable knowledge from makers who don't visit CKD.
I am setting up my Dust Master 1hp two-stage dust collector (got used, sits on 55gal drum) and I need to purchase a dust bag for it. The dust collector will be housed in a small insulated room attached to the outside of my grinding room and I plan to run metal ducting from it through the outside wall and along my "dirty bench" where my grinders, sanders will be. It came from a fabrication shop that used it on their metal grinders and sanders only for years. I asked the manufacturer about my application and metal grinding and he said the sell them mostly to metalworkers and it would work fine for it. He said they have never heard of any problems. Have you?
I called a distributer of Dust Master parts and they priced the 10 micron cotton sateen bag at $51 and the 5 micron knit polyester bag at $84. The gentleman I spoke with said I could get away with the larger micron bag (and save some $) since the collector would be in a separate room.
A few makers on the CKD forums posted concerns about fire. This has been a concern for me for a while as I have been planning this dust collection system. I am not sure how to handle it. I currently use a small water trap under my grinders and sanders, but don't know how effective it is. One person mentioned I talk to John Mallet at Tru-Grit about firebox designs to cut down on sparks getting to my collector, so I have a letter out to him and will post anything he tells me.
Also what would you recommend for micron size on my bag? Or if you know where I can find lower prices
on comparable bags. I called Delta and they want considerably more ($120!).
Any other suggestions or guidance about building an effective and safe, but not too expensive dust system for knifemaking would be much appreciated. I have searched the archives and have gleaned a number of ideas. It has taken me a few years to come this far on my system, but I still am unsure about the spark/fire issue.
FYI, I plan to hook up a standard single stage dust collector that I will switch over to when I am grinding wood, to keep wood dust out of the metal collector. From what I understand, this will help keep the system safe.
Thank you.

Worked real well till a few weeks ago. The concerns you have are valid and I knew about them going into this. I was profiling A Ti bolstered folder and got lazy and didn't keep my box under the grinder very clean. As a matter of fact I hadn't cleaned out the bag for the vac either for 6 months. Now I am just a hobbist and have only made like 8 knives in that time frame. The Ti caught fire in the grinder box and quickly went into and out of my vac bag. About a dozen or so burn holes right thru! Thank God the metal and stuff in the bottom of the bag didn't catch fire too. I ended up sewing patches for about an hour. Lesson learned....... Keep grinder box clean and empty bag from time to time.
