This dust collector pre-collects most sawdust, wood shavings, and debris into the bucket before they enter the vacuum, reducing filter clogging and maintaining strong suction. By trapping dust prior to the vacuum's filters, it significantly decreases cleaning or replacement frequency, while the metal filter blocks fine particles to double-protect and extend filter life. Compatible with standard 5-gallon paint buckets (sold separately), it features simple installation to connect the collector, bucket, and vacuum. Ideal for collecting sawdust, wood dust, drywall powder, concrete debris, water, and more, the kit includes 1 dust collector, 1 90° elbow, 1 2'×2.5 in. hose, and 1 metal filter—an efficient tool for safeguarding vacuums in woodworking, renovation, and other applications.
