Anyone else seen the ad for the 0.3 micron, 2HP DC from Grizzly? For $315 delivered? 0.3 micron? Mine’s in Mother Earth News. I checked Grizzly’s website and if it’s a typo, it’s on their website, too. What’s the catch, and how are they getting 0.3 micron filtration using bags? Anybody heard anything about this or have any links?
The ad indicates “1996 Wood Magazine editors choice for top value”, but the $315 price is the “Introductory Price”. Eight years is a long time to keep an intro price and/or to reference a review commendation.
Web-site indicated 12″ impeller, generating 11″ static pressure and 1550 cfm.
Free two stage seperator, too. Probably a trash-can version.
Incredible (truly) price for these specifications, if all is as indicated.
Any thoughts?
On a related note, would the powers that be (you webmaster types) give some thought to creating a dust collection folder?
Thanks.
Joe

I have one of those. The top bag is felt instead of the normal dacron so the fabric actually works more as the filter than the cake. Seems to work well as thisn't any dust evidence around it on the walls or ceiling. About my only complaint is that i haven't had enough opportunity to use it.
I think the 0.3 micron number is pure advertising hype. Sure, the bag will trap some 0.3 micron particles, but what percentage of them? 75%? 25%? 5%?
Manufacturers like Oneida, American Fabric Filter, and Penn State Ind rate their felt bags at 1-5 microns, and acknowledge that you need a lot of fabric area to maintain that level of filtration. I find it hard to believe that Grizzly has some exclusive, magic felt that produces 3x finer filtration than anyone else's.
The Grizzly bags are probably decent, and many users are happy with them, but I wouldn't let their 0.3 micron claim influence your buying decision.
