The combination brush is designed for cleaning rectangular/square ducts. The lightweight outer bristles are engineered to extend into the duct corners when rotating, ensuring thorough cleaning.
Stiffer bristles in the center provide support and stability, keeping the brush properly positioned inside the duct. The brush can also be used in round ducts.
The brush features a metal frame center with an M12 threaded connection, secured with a locking pin.
Attachment via M18–M12 adapter.
