Harbor Freight Dust Collector upgrade questions. - The
2021/08/22· So, like many, I have the 2HP Harbor Freight Dust collector, upgraded to a Wynn 35A filter. I am looking to get more airflow out of the DC and am wondering about an impeller and output upgrade, and have some questions #1. The Rikon P60-200-22 impeller seems to be the recommended replacement, but it appears to no longer be available.
