The DC Tromb 400 Twin pairs a dust extractor with an integrated pre-separator on one 115 V chassis, so 80 to 90 percent of the coarse material drops out before the filter cyclone sees it. It moves 212 CFM and suits concrete floor grinders running discs up to 20 in, and is ordered as a plastic bag plus Longopac or as Longopac on both stages.

The DC Tromb 400 Twin is the machine for the job that fills a collector faster than a crew wants to stop and change it. Dustcontrol puts an integrated pre-separator alongside the extractor on one frame, and that pre-separator takes 80 to 90 percent of the coarse material out of the airstream before the filter cyclone ever sees it.

Two single-phase two-stage fans do the pulling, the second cyclone catches what the pre-separator misses, and accordion hoses between the stages let the filter come out without dismantling the machine. The airflow is matched to concrete floor grinding machines running diamond discs up to 20 in across, and the whole assembly still rolls through a doorway and into a truck on its own wheels. This is built for the grinding crews putting down real square footage in a day, where a single-stage extractor turns into a filter-change schedule.

Common Applications

  • Extraction from concrete floor grinders running discs up to 20 in
  • Continuous dust collection on high-volume grinding where a single collector fills too fast
  • Extraction from handheld tools on the same single-phase supply
  • Collection of dry, harmful, non-combustible Class H dust

Selection Notes

  • Choose the plastic bag and Longopac build where the machine-side material is light enough to bag by hand and the bulk sits in the pre-separator sleeve; choose Longopac on both stages where every discharge should be sealed off without opening a collector
  • Both builds carry the same fans, the same filters and the same weight, so the choice is how each of the two stages is emptied, not what the machine can pull
  • The first letter names the machine cyclone and the second the pre-separator, which is worth confirming on the order so the consumables arrive matched to the build
