I am looking to find a blower fan that would work with my newly acquired laser engraver. I need something that is around 300-400cfm. Would consider a old hvac blower fan that had selectable variable speed that I could wire up to a rotary switch and build an enclosure for. I have been looking for a 1hp dust collector blower fan as my primary solution.
The fume extractor I got with the laser engraver needs over $1200 in work currently so it likely won’t be functional for a few months. The filters for it are crazy expensive and not available off the shelf.
I figured someone may have something usable laying around or know of a better idea. Thanks!!
