I am wondering how bag filters work with a cyclone. My filters are plugged up at this point,after about 4 years of use. I am using this dust collector in a small (2 man)cabinet shop. I work about half the year in my shop but am gradually working more and more in the shop heading towards full time. My collector runs about half a day on average when I am in the shop. Machines hooked up : Sliding t.s.,cabinet saw, 20 planer,16 jointer,two shapers,edge sander,edge bander,2 bandsaws etc. Usually two machines running at the same time at most. I have a drum sander that gets used sparingly. I am looking at getting bags made by American Filter Fabric or a similar source. I would like anyone with experience to let me know how good these work. I have a 16' high ceiling so am looking to get tall bags made. I am thinking of cutting down a couple of barrels to catch dust and having the bags cinch over these drums. Would it be a good idea to have the discharge of the cyclone into a plywood box to help protect the bags ? More of a baghouse set up. Also is it possible to clean the spun polyester filters that are on my Grizzly now? I am talking about taking it apart and washing etc.trying to restore it. Or is that just a waste of time ? Lately the collector has way higher back pressure,I have noticed that more fines are ending up in my bags under the filters. Also the plastic bags themselves are very taut when the collector is running. Air movement out of the filters is reduced significantly from what I remember when this was first put in use.Could there be another issue here as well that causes some of these problems?
