Axiom's overarm dust collection attachment pairs a rigid welded 4'' duct with a flexible hose that lets your gantry move freely across its full range of motion. The rigid arm provides a sturdy structure that moves with your machine—no need for elaborate overhead fastenings, and no need to detach or reattach components when you roll the CNC across the shop. The clear flex-hose connects to your Axiom Dust Shoe (sold separately), while the 4'' port at the opposite end of the arm connects to your dust collector. Includes mounting hardware, flex-hose, hose clamps and welded arm that is adjustable to fit any Axiom AR4, AR6, AR8 or AR16 CNC router.
