How The Dustcontrol DC Tromb 400 Twin LL Compares To The Twin cL
Contractors evaluating DC Tromb Twin discharge configurations usually face this question: should I get the mixed intellibag/Longopac Twin cL, or this all-Longopac Twin LL for maximum continuous, minimal-interruption disposal?
| Feature | Dustcontrol DC Tromb 400 Twin cL | Dustcontrol DC Tromb 400 Twin LL |
|---|---|---|
| Machine Container | Intellibag plastic sacks | Longopac continuous bagging |
| Pre-Separator Container | Longopac continuous bagging | Longopac continuous bagging |
| Bag Changes | Mixed, one continuous and one bag-based | Fully continuous on both stages |
| Best Suited For | Standard high-volume jobs | Maximum continuous operation with minimal interruption |
Product Description
- Portable but very powerful dust extractor suitable for large quantities of dust due to its integrated pre-separator.
- Particularly suitable for concrete grinding since 80–90% of the coarse materials are separated in the pre-separator. The remaining dust goes into the filter cyclone.
- Different discharge arrangements can be combined (intellibag (c), Longopac (L) and container (a): c+c/ c+L /a+L / a+a / L+L
The DC Tromb Twin is a portable but very powerful dust extractor suitable for large quantities of dust due to its integrated pre-separator. It is particularly suitable for concrete grinding since 80–90% of the coarse materials are separated in the pre-separator. The remaining dust goes into the filter cyclone. The DC Tromb Twin is a flexible machine since it is powerful enough for most applications yet it can be easily moved and transported. The air flow capacity is suitable for concrete floor grinding machines with diamond discs of up to 500 mm/20” diameter.
Different discharge arrangements can be combined (intellibag (c), Longopac (L) and container (a)): c+c/ c+L /a+L / a+a / L+L. The first letter refers to the machine and the second to the pre-separator. These are our standard combinations and more combinations are possible.
