After getting my unisaw this summer i immediately made up some zero clearance inserts. I've since noticed a lot of sawdust spitting up onto the table in a diagonal strip across the tabletop from the insert towards the left front corner of the tabletop and thought this was strange considering the advanced collection system on this saw. I could also detect more dust in the air around the saw. My Grizzly 1023 didn't seem to suffer from this problem.
I decided to see if the collection was better with the Unisaw's factory(nonZCI) insert installed. As it turns out there is virtually no dust anywhere with the more open factory insert.
Has anyone noticed reduced dust collection on their table saw when using a ZCI? I'm guessing that there is reduced airflow around the blade causing the problem, although as i've stated i never noticed the problem on my 1023. John
