Dust Collection Machines

A HEPA dust extractor filters particles as small as 0.3 microns at 99.97% efficiency — the threshold set by most occupational health standards for fine wood dust. The Mirka HEPA Dust Extractor is appropriate for MDF routing, fine sanding, and working with sensitizing exotic species where standard shop vac filters pass the most dangerous fine particles back into the air.

A dust extractor captures dust at the tool — connected directly to a sander, router, or saw port — before it becomes airborne. An air filtration unit like the Rikon Air Filtration System hangs from the ceiling and filters ambient shop air continuously, capturing the fine particles that escape tool-mounted collection. Both work best together.

CFM (cubic feet per minute) measures the volume of air an air filtration unit processes per minute. A 450 CFM unit like the Rikon model cycles the air in a typical one-car garage shop multiple times per hour. Match the CFM rating to your shop's volume: larger or dustier shops benefit from higher CFM units or running the unit continuously during and after work.

A coaxial vacuum hose routes the vacuum tube inside or alongside the power cord in a single integrated cable. This eliminates the tangling and floor clutter of a separate power cord and vacuum hose, which is particularly valuable when sanding large panels or moving a sander continuously across a workbench.

Replace the dust bag when it is approximately two-thirds full — waiting until it is completely full reduces suction significantly. Mirka replacement dust bags are available individually and in multipacks. Running an extractor with an over-full bag also puts extra strain on the motor over time.

For finish sanding, especially on MDF or sensitizing species, a HEPA-rated dust extractor is strongly recommended because standard shop vac filters allow the finest particles to pass through. These ultra-fine particles stay airborne the longest and penetrate deepest into the lungs. A shop vac handles chips and coarse dust adequately but is not a substitute for HEPA filtration during fine sanding.

Dust extractors produce high suction at relatively low volume and are optimized for handheld tools and sanders. A table saw or planer produces high volumes of chips that overwhelm most extractors quickly. Dedicated dust collectors move much higher air volumes suited to stationary machinery. For whole-shop coverage, combine a dust collector for machines with an extractor for portable tools and sanding.

Consider the type of tools you use most (handheld vs. stationary), the filtration level required for the species and materials you work with, and whether you need portability or can install a fixed system. The Infinity Tools learning center covers dust collection planning, or contact the team for a recommendation.

The Mirka DEROS Dust-Free Sanding System is a complete package that includes the DEROS random orbital sander and a compatible dust extractor connected via a coaxial hose. The sander and extractor are designed to work together as an integrated system, with the extractor running automatically when the sander is switched on.
