Grizzly G0852 quiet dust collector

[Garrad Miller]

Anyone tried or know much about these?

Db rating is listed the same as other similar models oddly.

Less cfm but more sp than the similar 1.5hp standard cyclone.

The outlets down low are rare for a cyclone but would work better in my shop is why im looking at this model but there is zero info out there on this.

The impeller on that machine is directly on the intake, so whatever it sucks up will go through the impeller, which will make more noise, especially if it is a screw or nail, etc.

Unfortunately, that is what gives it the low intake.

The shape of the cone is an example of what are called "short" or "stubby" cones, and do not separate dust from the air very well, so a lot of dust is going to the filter, to clog it more often.

Most cyclone systems are set up with the impeller after the separator, to avoid debris (wood or otherwise) from striking the impeller.

Better separating cyclones have longer cones that that. From Grizzly, see the G0777, for example. Though neither of these have stellar filtration specs, and will pass too much harmful dust back into the shop air for me.

I agree with everything Andy said . I would not buy it .

[Frank Pratt]

And I agree with Andy and James. I'd pass.

1.5 HP collector is only good for direct connection to an individual machine with a very short piece of flex, so there would be lots of moving it around.

Thats a good point on the impeller location, would make me have to be more careful with anything large or metal.

[Andy D Jones]

Yeah, having metal objects strike the impeller is not just noisy and potentially damaging; some metal pieces, especially if broken/sheared by the impeller, can get very hot, and could cause a fire in the collection bin. If separated before the airstream gets to the impeller, there is no such danger. (Note however that aluminum impellers do not spark when struck by ferrous metal objects.)

So it would not be the best choice if you want a floor sweep inlet (into which you sweep debris off the shop floor (or bench top).

Having designed a lot of industrial ductwork this thing makes me cringe.

1. Terrible fan inlet condition

2. Fan must endure incoming junk as noted above

3. Flex used where solid ductwork would have been better

4. Hard turn into the cyclone

5. Poor inlet condition into the cyclone

6. Stuby cone as mentioned above

7. Hard turns in the 'over the top' duct

8. High velocity and off center inlet to the filter

That's just what the picture shows. This thing will have weak performance for the power it uses.
