Have a question for the dust collection experts. I'm stuck on a 1-1.5HP DC system, as I have max a 20amp 110v breaker available. My current shop is a 1930 garage, with 2, 20amp lines run into it from the main panel at the house. There is no option to run 220v as the main panel is out of space. We're also going to be at the current location for max 2-3 years, so I do not want to make a large investment into electrical.
I will be using this DC for me DW735 planer (4" port) , an 8" jointer (4" port), 14" bandsaw (1.5" port at blade, 2.5" port under) and a SawStop JSS with a 2.5" port on bottom and a 1.5" port on top. The plan is a 20 foot Rockler flex hose which will be moved tool to tool. Everything is on one side of a 2 car garage, so that setup will work great for me. I use a separate shop vac style dust extractor for my track saw and sanding needs.
After doing some research, I have narrowed it down to these options:
2 stage - Grizzly G0860. It's a "1.5hp" motor with a 12" impeller, so same really as the Harbor Freight motor (but already upgraded), but has a nice cyclone, canister, and pleated filter built in. These are currently on sale for $750 delivered, which seems like a great deal (https://www.grizzly.com/products/gri...ollector/g0860) I priced out and looked at doing a HF DC 2 stage retrofit with a dust deputy, but it will not be as "neat" as this, take up just as much space, and actually even cost more
1 stage - Harbor Freight motor, wall mounted along with a canister filter (https://www.rockler.com/canister-fil...dust-collector). This setup will cost $450
I have read that if you have such a low HP dust extractor that actually using a 1 stage setup can create more CFM at your tool and actually be more effective, at the cost of potentially clogging up the filter. Is this true? The 1 stage is obviously smaller (big bonus in my small shop), cheaper, and the only negative seems to be that it has a 14 gallon bag vs the 20 gallon setup of the Grizzly. Will the filter get super clogged up super fast? Will it actually offer MORE dust collection at the tool for me?
HALP!
