Why the GRINDEX1200LPS leads this comparison
- 510 m³/h vs 360–420 m³/h airflow — the GRINDEX1200LPS delivers up to 42% higher airflow than the DC Tromb 400 at equivalent motor power. Higher airflow directly improves dust capture efficiency on concrete grinding and surface preparation operations.
- H14 equivalent HEPA + PTFE filtration — PTFE cartridge filters provide superior dust separation and filtration durability versus the DC Tromb 400's polyester primary filter. H14 captures 99.995% of particles vs H13's 99.95%.
- 20,500 cm² filter area — the largest filter area in this class. More filter area means longer filter life, more consistent suction and less operator intervention during operation.
- Fully automatic continuous filter cleaning — maintains airflow throughout the working day without operator intervention. The DC Tromb 400 uses automatic/reverse pulse cleaning which requires periodic activation.
- 22m Longopac continuous bag system — significantly more collection capacity before bag change than a standard Longopac. Critical for continuous grinding operations where stopping to change bags costs productivity.
Application — concrete grinding and surface preparation
Both machines are designed for concrete grinding, shot blasting support, floor preparation and large-area silica dust control. The GRINDEX1200LPS's higher airflow makes it the stronger specification for large grinders and multi-tool setups where dust generation rate is high. The DC Tromb 400's lighter weight (46kg vs 65kg) gives it a handling advantage in confined spaces.
For silica dust compliance under HSE EH40 (RCS WEL 0.1 mg/m³ 8-hour TWA), both machines provide compliant H-Class extraction. The GRINDEX1200LPS's higher airflow and H14 filtration provide a greater compliance margin for high-output grinding operations. See: Silica dust and engineered stone hub
