Dust Collection Basics: Keeping Operations Clean, Safe, and Productive
How to Stop Dust from Quietly Ruining Everything
Every shop fights downtime. A CNC stalls, a forklift breaks. We all know the drill.
Dust is different. It doesn’t stop you with a bang. It creeps. Slowly. Until your crew is pushing brooms and emptying bags instead of running machines.
The fix? A dust collection system that works in the background. No drama. Just clean air, safe people, and steady production.
Where Dust Comes From
Dust shows up every time material drops. Out of a chute. Into a bin. Off the line.
That little pile at the end of the line? It is more than waste. It is profit and time floating away.
How to control it:
Keep drop heights low.
Guide material into containers and chutes, not piles.
Slow the dumps. A chute or piece of flex hose does the trick.
How to Control It: The Parts That Matter
Hoods and Shrouds
First line of defense that catches the dust. Keep them small and close to the source. We can custom-make hoods to fit your specific need.
Ductwork
Airflow is the lifeline. If it is not balanced, nothing works right.
Clamp-Together Duct (CTD): Our rolled-lip CTD uses a gasketed, over-center clamp to clamp together your required length. Thanks to our 11” adjustable sleeve and integral adjustable collar on each fitting. This system is infinitely adjustable and can save up to 70% on installation time! All components and special fittings are provided.US Tubing: Provides a liquid and oil mist-tight system thanks to our Ultimate Seal clamp and gasket system with a Vanstone-flanged end. Get the tight seal of a flanged and gasket duct, but with the ease and speed of a clamping system.Flanged Duct: For big runs. From 3 inches up to 40 inches and beyond. Rock-solid, sealed connections.
Separators
Think of them as the bouncers. They keep bulky waste out of the filters.
Legend Cyclones: Perfect for coarse, heavy dust. Extend and improve your system performance and extend filter life by using a cyclone to remove large amounts of abrasive material prior to your collector.
Legend Inline Separators: This groundbreaking, patent-pending technology is ideal for shops with high waste volume that is less than 1” in diameter. Ours captures up to 90%* of bulky material before it hits your main collector. This protects your filters and keeps things running smoothly because you’re not as busy changing collector bags.

Waste Collection
Dust has to land somewhere. Dumpsters, hoppers, bags….
Legend Self-Dumping Hoppers: Lids seal tight. Dumping takes minutes, not hours. Forklift-ready. Sized in Small (0.75 yd), Medium (1.4 yd), and Large (2.2 yd).
Quick-Change Hoppers: First of its kind! This pneumatically sealing hopper rolls under our 10 HP and 15 HP Baghouses, collects, rolls out with casters and forklift-ready pockets, and features guillotine-style bottom door for easy dumping. Captures the equivalent of ~6 collector bags of waste! Use two to really speed things up (one dumping, one collecting).
Collectors
The final stop for fine dust. Baghouses or cartridge filters are your workhorses.
Legend Baghouse Collectors (5–15 HP): Built for woodworking, plastics, and other dry dust. Pair our 10 HP and 15 HP models with a Quick-Change Hopper to see dust collection efficiency in action.
Get the Design Right
Dust collection is simple math, but it has to be exact
Airflow = opening size (cross-sectional area) × capture velocity
Duct velocity: High enough to move dust, not so high it wastes energy.
Filter area = air volume ÷ face velocity
Example: 6,000 CFM ÷ 8 FPM = 750 square feet of filter media.

Safety First
Dust isn’t just messy. It can be explosive. NFPA standards exist for a reason.
Inspect and replace filters on schedule.
Treat maintenance as part of production, not overhead.
The Bottom Line
A good dust collection system doesn’t call attention to itself. It just works. Shift after shift.
Ignore it and you lose uptime, burn money on filters and bags, and put people at risk.
Invest in it, and you gain efficiency, clean air, and fewer headaches.
