Improve Dust Collection Efficiency and Safety with Pre-Separators

In high-dust environments like concrete floor preparation, joinery, or surface grinding, airborne dust isn’t just an inconvenience. It represents a serious health risk, a potential hazard to your equipment, and a productivity killer if extraction systems fail or clog. That’s where cyclonic dust pre-separators come into play.

What Does a Cyclonic Separator Do?

Cyclonic pre-separators are engineered to handle the initial load of airborne dust and debris before it reaches your dust extractor. These units work on a principle of centrifugal separation.

As contaminated air enters the separator tangentially, it spins in a circular motion inside the chamber. This motion creates centrifugal force, which pushes heavier particles outward toward the wall of the chamber. Gravity then pulls these particles down into a collection bin or Longopac system. Only the finer, lighter dust proceeds into the vacuum’s filtration system.

This reduces filter loading and extends the lifespan of your vacuum’s filter cartridges. It also preserves airflow and maintains high suction performance over longer periods of operation.

• Prevents filter clogging by capturing up to 95% of material before it reaches the vacuum
• Increases equipment uptime by reducing the frequency of filter changes and vacuum maintenance
• Improves onsite safety by reducing airborne particles that contribute to respiratory hazards
• Simplifies waste handling when separator is equipped with a Longopac collection systems

These performance gains aren’t theoretical—they’re achieved every day on worksites using high-efficiency separators. Whether you’re looking to improve safety compliance when managing silica dust or reduce the load on your H-Class vacuums during floor prep work, the right pre-separator can transform how your system performs. Dustcontrol models stand out for their engineering quality, high safety considerations and integration with professional dust extraction setups.

Dustcontrol DCF 2900L Pre-Separator

This external cyclone separator is designed to pair with units like the DC 2900 H-Class extractor. With its high-efficiency cyclonic chamber and Longopac waste handling, it’s ideal for capturing concrete dust, wood shavings, or other coarse material before it reaches the main vacuum. Lightweight and portable, it’s a scalable option for mobile operations.

Dustcontrol Twin Tromb H-Class Vacuum with Built-in Separator

This dual-motor industrial extractor incorporates its own built-in separator. The internal cyclone captures large volumes of heavy dust while the twin filters handle residual fines. This vacuum is built for surface preparation professionals using machines up to 530 mm in diameter, and provides consistent high airflow over long shifts. The DCF Tromb separator itself is also available individually for those who already have a Tromb400 or similar vacuum
