WOW is all i can say in the noise level and amount of dust collection this thing does over the old one . I did a steel rim for a friends little pickup truck and the back side was rusty like normal and i didn't have to slow down to let the dust settle . This unit will suck the gloves in to the box like your wearing them it pulls that much air / cfm . I even left the old collection port 2.25" open for more air in to the box over the stock port on the back .
