Shipping: LTL freight. Commercial delivery preferred.

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.

Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

  • Orders up to $5,000: $279
  • Orders $5,000 to $10,000: $347
  • Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

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
