Product Overview
Delfin DBFV 05/10 Z22 is engineered for applications featuring particularly heavy, sticky, or agglomerating dust. The integrated vortex pre-filter separates these large particles before they reach the main filter, significantly extending filter life and reducing maintenance costs.
Like all Delfin ATEX models, DBFV Z22 comes with H14 HEPA absolute filter, maintenance-free side channel blower, and robust steel construction for Zone 22 certification. The integrated vortex technology makes it the optimal choice for dust types that cause rapid filter clogging.

Vortex Pre-Filter Technology
The integrated vortex system creates a cyclonic airstream that separates heavy particles and directs them directly to the collection tank without burdening the main filter. This is especially important for oily, fatty, and sticky dust types.
Options and Accessories
DBFV 05/10 Z22 can be supplied with various custom configurations:
- Stainless steel construction – for aggressive dust and moisture

Frequently Asked Questions
V stands for vortex - an integrated vortex pre-filter that separates large and heavy particles before the main filter, extending filter life.
The vortex pre-filter increases overall system efficiency, reduces filter clogging, and significantly extends operation time between service intervals - often doubling filter life.
DBFV is ideal for heavy, sticky, or agglomerating dust types where a pre-filter creates significant operational savings.
Yes, DBFV can be used for all dust types. For purely fine dust, DBF (without pre-filter) may be more economical.
With the vortex pre-filter, filter lifetime can double compared to DBF depending on dust type and volume.
No, DBFV is fully maintenance-free like DBF thanks to its side channel blower with no wearing parts. The vortex section requires no maintenance.
ATEX-certified dust collection for hazardous areas
We provide design, installation, and certification assistance for dust collection systems in Zone 20/21/22 environments. DBFV with vortex is ideal for heavy dust loads.
