These are the Snap-In bags for the Torit RF series dust collector, formerly known as the Carter Day RF. The product you see below is the 10 foot bag, in Singed Polyester. We offer the same bags in Glazed, as well as Nomex, and Tetra-Tex. We also have the 8 foot, as well as the 12 foot versions at similar pricing. If you are looking for improved filtration efficiency, better than a 16 oz. polyester can yield, we can build these in the Dual-Density “micro-denier” felt. In addition to the Snap-Ring type, we also build the Boltsafe type bags for RF, HPH, HPT, and HPW series collectors. Give us a call to discuss.
