I’m looking for advice regarding which kind of dust collector I should buy.
I have a basement shop that I’m just setting up. I have ample floor space, but limited headroom. (83” from the floor to the joists, and another 5” between the joists that I could spill into if necessary). The only major dust/chip producers I have now are a Ridgid R4511 TS and a router table, but I anticipate adding a 6” jointer and a planer eventually. I will never need to run more than one tool at a time and I can configure my shop so that the major tools are no more than 10 feet from the dust collector. I have an available 220v outlet, but I could do 110 as well. My main concern with a dust collector is filtering out as much harmful dust as possible, preferably down to 0.5 micron. Given the way the house is constructed, any dust in the basement will find its way up into the rest of the home. While I can wear a respirator while I’m down the in basement, I don’t think my wife would be too happy wearing one in the living room. She also has some mild asthma issues that I assume the dust will aggravate.
Considering that this is a health issue, I’m somewhat flexible on cost. I think I could stomach upwards of $1000 for the dust collector, filters, and all ducts. Given my desire to filter down to .5, I feel like I either need (1) a big single stage collector (2hp or better) with an added baffle, and an aftermarket filter to replace the top bag, or (2) a 2hp or better two stage cyclone.
My concern with a single stage is that it may not move enough air to capture all the fine dust while the machine is running and that an added baffle may decrease efficiency and not filter out enough dust to prevent filter clogging.
My concern with a cyclone is cost and height. Ideally I’d find a less tall, used cyclone that would suit my purposes, but given the rarity of short cyclones and their general newness I wonder if that’s a possibility. A lot of the low end cyclones seem to only move 800 CFM max. I wonder if that’s enough to keep the really harmful dust from escaping the negative pressure created around the tool while running. I realize that this may sound like overkill to a lot of people here, but I’m of a mind to set things up right from the beginning and to not skimp on health and safety issues.
As to any suggestions that I build my own whatever, I’d be comfortable making a baffle or a Thein separator, but not comfortable doing the metalwork necessary to make my own cyclone.
I’d greatly appreciate any comments about my thoughts as well as specific make/model suggestions.
