Built two hay filters for my non wk. ranger gasifier with heated hopper, i ran it with out hay filter, testing the cyclone method, no luck with cyclones too rid the silt. Seems too heat up quik too drive. Though cools down rather fast as there aint any steel in the hearth area with my ceramic blanket burn tube, my wood this year may be dryer than last gasifier test. Heated hopper working good , though i would like too insulate around it too lesson the heat rise efects. Seems too run good so far. Here are my hay filters, about 5 gallon in each canister, I due have a sock type filter behind the back tires allso.
Got it bolted too a plated welded too the frame good and solid and will be adding a couple bolts up top too secure allso.Hopefully it will work for few hundred miles before it needs cleaning.
