For dust control, I’ve been using an old shop vac and Dust Deputy. It worked well enough, but then the vacuum died spectacularly. It stopped running with a column of thick smoke and then melted down. Rather than abusing another shop vacuum, I started looking for a dust collector.
I opted for the 2 HP model from Harbor Freight. It’s very popular and a good price that’s even better with a 20% off coupon. I also got the larger Super Dust Deputy since the little bucket version worked well for me. Using the conical cyclone, debris enters, swirls around, and drops to a collector rather than going through the blower motor into a collection bag. The primary purpose is to prevent solid chips/chunks, etc from hitting the motor’s impeller and causing damage. But it’s also extremely efficient at capturing anything that gets sucked up.
I’m not using the bagging system with Harbor Freight Kit. I’m simply venting outside. The advantage here is that only the finest dust will escape the Dust Deputy, but this fine dust is the most problematic. It’s the most dangerous to inhale, and it’s also the most difficult to filter. So, rather than building an expensive filtering system, I’m just going to just exhaust it outdoors. Once it snows, I’ll be able to see how much dust is being vented and whether I need to rethink it. So far, it’s working great.
The other advantages of this setup are it’s a small footprint. It’s vertical at less than 2-foot by 2-foot. The other advantage is there’s no filter to restrict airflow, so it should help increase power or at least help counter the restriction from the cyclone.
I opted to go for the newer 4-inch Super Dust Deputy. I was hesitant to buy a smaller unit than the larger cyclone with 5-inch connections. I was concerned if it would hurt power and not be as efficient. So far, it seems perfectly fine. It seems Oneida designed this version of the Super Cyclone for the popular Harbor Freight and similarly sized dust collectors. This is a turn-key system that includes a 15-gallon drum. The cyclone fits directly on the drum and doesn’t require a lid or cutout. It also includes a foam gasket to get a tight seal. The output is 4″, which is the typical for small to medium shop dust collection. It also includes a fitting/adapter out of the top for 4″.
For my setup, I made a wall mount with 2x4s. I then just set then fan blower so the input is facing the ground. I didn’t mount the blower anywhere. It’s heavy and the blower input sticks out so will keep it from sliding off. Once mounted, I used the Harbor Freight duct adapter and 5″ output hose. I cut a hole in the wall, installed a 5″ wall duct baffle, and connected it all with clamps. I also cut a short length of the 5″ hose and connected that to the lower input with a clamp. Then used a 4″ reducer. Then I attached a length of 4″ hose to the Super Dust Deputy. Out of the Harbor Freight kit, I’m just using the blower, duct adapter, and hose.
This gives me a straight line for airflow with only a minimal curve on the output. I mounted the lower at a height that was convenient for me to reach the switch. I thought about sitting the drum on a cart for convienent emptying and maybe steal a little extra shop storage space but didn’t I don’t have a clear path to wheel out the drum anyway. I also didn’t want to directly connect the blower to the Super Dust Buddy because I thought it might make it more difficult to empty the drum. I’m thinking about using some bungee cords to hold the Super Dust Buddy when emptying, but it seems light enough that the hose clamps can support it hanging.
Lastly, I need to work on connections. I intend to simply move the 4″ hose to machine to machine. My shop is small and only the table saw is stationary, so I don’t have fixed stations for duct work.
