Topic tags/keywords: grizzly dust collector

Hey everyone I’ve been lurking this forum for a while, first time posting however.
I’m looking to put a dust collection system in my two car garage. Looking at grizzly a site they offer a 2hp unit with a 1 micron “canister ” style filter for 445. And a 3 HP unit with two filters at 2.5 microns for 425

Question is whether the filter is worth less HP or vise versa

Harbor Freight 2hp collector currently on sale with coupon from Wood magazine for $150 + Wynn Nano filter (99.9x of .5 micron particle) $170 + shipping. Better capabilities for less money.

The jump to the cannister filter is a step in the right direction….not just for the improved filtration, but for the improved airflow….a cannister will have 5x to 6x the airflow of a standard bag. The 2hp Griz has 12-3/4” impeller, and a steel chute that really moves a lot of air. (FWIW, the HF DC has an impeller in the range of 10-3/4”, and isn’t a true 2hp motor….it’s a good value if you’d rather save some money, but doesn’t perform at the level of the 2hp Griz). I don’t think you’d need the capacity of the 3hp DC….it offers a lot of potential, but you’d need to add ~ $250 – $300 worth of cannisters to get the filtration level in the range of the 2hp unit.

Note the difference in impeller size:

+1 on kotscotts’s comments. good advice that will get you good dust collection performance. when you get it, add a baffle to the drum ring and keep as much dust as possible out of the filter, like this:

The 3 HP model with canister filters has a sound rating of 87 db. The 2 HP model has a sound rating of 74 db. I would assume the bagged model of the 3 HP is very close in sound rating to the 3 HP canister model. Since the decibel scale is logarithmic that is a huge difference in the amount of noise they produce.

I have the 2 HP HF and looking back I probably should of just went with the 2 HP Grizzly and been done with it instead of trying to mod it to get it to behave like a more capable DC.

Thanks for the advice. Also, would the 2HP be strong enough for permanent PVC pipes and gates?

about 2 years ago I was standing in the Grizzly store in Springfield, Mo. looking at those 2 dust collectors sitting onm the showroom floor. I was compairing the differences when a man walked by ( a customer) and said in passing. Go ahead and get the larger one then you won’t have to take the small out and buy the larger on later like I did. So I had that tucked in th eback of my mind when I went shopping. I ended up ordering a 5 hp Clear Vue. I have a 30×40 shop. I added a 2 ft extension to the end so when I installed the unit I actually housed it in the addition and I piped through the wall.

grandpa implies a good point relative to your question about the 2 hp being able to support fixed piping. it would depend on the size of the shop. my 12×20 shop does quite well with one run of fixed pipe and a 1.5hp 50-850. in a shop 5 times the size of mine, i wonder if a 2 hp would be adequate.

@knotscott…

Could you expand on that? Not sure I follow.

Have your say...
