Questions and answers
Can the DBF 05/10 ACD be used in an ATEX-classified Zone 22?
No. The ACD version is only for areas that are not ATEX-classified. If the machine stands in Zone 22, the DBFV 05/10 Z22 (category 1/3D) is the right unit.
What is the difference between DBF 05 ACD and DBF 10 ACD?
DBF 05 ACD has 0.37 kW, 100 m³/h and 1,500 mmH₂O. DBF 10 ACD has 0.95 kW, 150 m³/h and 2,000 mmH₂O. Both have a 15 L container, safety valve and H14 filter.
What does the marking Ex h IIIC T135°C Da mean?
Da means the inside of the unit is built for an atmosphere corresponding to Zone 20, where the dust is collected. The surroundings are not ATEX-classified, so there is no category for the outside (1/- D). Source: Delfin price list 2026.
What is the difference between ACD and ATEX?
ACD (Appliance for Combustible Dust) covers vacuums for combustible dust in areas that are NOT ATEX-classified – typically because the operating pattern or dust quantity does not trigger classification. ATEX vacuums are certified to the ATEX Directive (2014/34/EU) and may be used in classified zones.
What filter class is fitted?
The DBF 05/10 ACD has an H14 absolute filter with 99.995 % efficiency according to the MPPS method (EN 1822-5) after the bag filter.
How is the dust collected?
Dust is collected in a bag of antistatic polyester ANT M PTFE. One disposable bag is included, and more can be bought individually.
