These brushes can be used with either a rotary brush machine or a hand driller shaft, and are perfect for removing dirt from small rectangular ductwork. These brushes should be around 10% larger than the intended duct size so that the longer bristles drag and reach into the corners of the duct.
For different type of connection, please contact us. We are able to products any amount of brushes for any type of connection.
