Aircompact Cartridge Dust Collector
Coral's recommended range for CNC woodworking. A vertical cartridge design with jet cleaning, sized for continuous-duty nesting cells where ceiling height or floor space is limited.

CNC Router Dust Collection
A CNC router's spindle travels across the whole table, so the point where dust is generated keeps moving. Coral designs capture around that motion, not around a single fixed hood the way a moulder or planer would need.
Why a Fixed Hood Falls Short
CNC router dust collection chases the tool.
Start with the failure, because it is the one thing about this machine class that no amount of extra filter area will fix.
A hood bolted to one corner of the table cannot follow a spindle that travels the full length and width of a nesting bed. Capture on a router is built into the head instead: a shoe or brush guard that rides with the tool, working against a plenum beneath the spreader table so suction stays useful wherever the program has sent the spindle at that second.
That single mechanical fact is the whole difference between this page and moulder and planer dust extraction. On a moulder the cutterhead never moves and the stock feeds past it, so extraction is a fixed-outlet problem measured in the volume of material coming off. On a router the stock never moves and the tool does, so extraction is a coverage problem measured across an area. The two look similar on a machine list and behave nothing alike once the ducting is drawn.
Coverage is also why a vacuum hold-down table belongs in the conversation rather than being treated as a separate system. The table pulls air down through the spoilboard to stop parts lifting, and that airflow occupies the same cutting zone the dust shoe is working in.
Cells cutting mostly sheet stock will usually want panel saw dust collection settled for whatever beam saw sizes the sheets, and shops where the router sits inside a wider carcass and door operation should read this alongside cabinet shop dust collection.
Inside a Nesting Program
The tool moves, not the stock.
CNC woodworking covers nesting routers, machining centers with automatic tool changers, and point-to-point boring and engraving heads. On a nesting cell, a full sheet is loaded flat on the table and the gantry drives the spindle across the whole surface to cut, drill or profile dozens of parts in one program.
One program can therefore put the head at a different point on the table for every part it produces. Where dust is being made in any given second is a function of the toolpath, not of a fixed station on the floor, and the toolpath changes with the job.
Cartridge Media for Router Dust
Cartridge filtration.
Coral's recommended range for CNC woodworking handles the fine dust and router chip mix a nesting cell produces without needing extra floor space.

Nesting cell questions.
How does a nesting cell affect dust capture compared to a single router?
A nesting cell cuts many parts out of one sheet in a single program, so the tool travels across the full table repeatedly, and suction needs to stay consistent everywhere the head can reach, not just near one fixed edge.
Can dust buildup affect CNC router accuracy?
Dust intrusion into linear rails, ballscrews and the tool changer can affect positioning repeatability over time, so consistent extraction at the cutting head protects precision as well as air quality.
Does the dust shoe on the router head replace a shop extraction system?
No. The shoe is the capture point at the tool, and it still has to be connected to a collector sized for the duty cycle the cell actually runs. The vacuum that holds parts down is a separate service and is not doing the filtration work.
What kind of waste does a CNC router actually produce?
A mix, and that is the awkward part. Profiling and pocketing throw router chip, while finishing passes and cuts in melamine or MDF release much finer particulate, and the collector has to take both inside the same program.
Guarding Positioning Accuracy
Protecting precision components.
A CNC router holds tight positioning tolerances, and dust is one of the more common threats to that accuracy over time.
01
Protects Rails & Ballscrews
Fine dust working into linear rails and ballscrews over months of running can affect positioning repeatability if it is not captured at the source.
02
Keeps the Tool Changer Clear
Automatic tool changers depend on clean tapers and clean sensors, both of which are vulnerable to dust drifting from an uncontrolled cutting zone.
03
Reduces Unplanned Downtime
Consistent extraction at the head means less time spent clearing dust from the table and vacuum zones between nesting cycles.
Running a nesting cell that needs cleaner capture?
Table size, program mix and cell layout decide the sizing, so the free factory visit starts with all three rather than with a model number.
