Depureco MINIBULL H ACD INERT
The Depureco MINIBULL H ACD INERT is the compact single-phase INERT solution for reactive metallic dust: two bypass motors, 45 L container and an integrated neutralising liquid bath that inactivates aluminium, titanium, magnesium and lithium dust at the moment of collection. Used on shooting ranges for lead collection, in 3D-printing laboratories with reactive metal powders, and in smaller R&D environments where ATEX zone classification of the room is not practical. Internal Zone 20 construction per IEC 60335-2-69 Annex AA and INERT performance-tested to EN 17348:2022.

Questions and answers
What does INERT technology mean for the Depureco MINIBULL H ACD INERT?
INERT technology means the Depureco MINIBULL H ACD INERT collects reactive metal dust in a neutralising liquid bath rather than in a dry bag or container. The dust is channelled directly into the liquid and inactivated instantly, before it can react with oxygen, heat or sparks. For single-phase small models like this one it is critical when handling reactive dust in small to medium quantities -- for example lead from shooting ranges or metal powder from 3D-printing laboratories.
What types of reactive dust is the Depureco MINIBULL H ACD INERT intended for?
Reactive metallic dust in small to medium quantities: lead and primer residue from shooting ranges, aluminium and aluminium alloys from 3D printing and CNC, titanium from medical and aerospace production, magnesium from light-metal machining, lithium metal from battery laboratories, plus pyrophoric powders from aerospace and defence. For smaller production volumes (e.g. a shooting-range chamber or a 3D-printing booth) this single-phase model fits precisely.
Is the INERT system tested to EN 17348:2022?
Yes. The entire Depureco INERT range is performance-tested to EN 17348:2022 -- the harmonised European standard for industrial vacuums in ATEX zones. The test confirms the neutralisation bath actually inactivates reactive dust under real operating conditions, not just in the laboratory. Documentation sent on request.
Why ACD rather than ATEX on this model?
ACD classification is used because many shooting ranges, 3D-printing laboratories and R&D departments are NOT ATEX-classified rooms even though the dust is reactive. IEC 60335-2-69 Annex AA covers precisely that scenario: ACD approval of the machine without requiring ATEX zone classification of the area. For formally ATEX-classified zones an INERT variant exists in the ATEX Dust category.
How is the neutralisation bath maintained?
The neutralisation bath is replaced after each fill (approx. 5 L of collected material for single-phase INERT models). The used liquid with inactivated dust is disposed of as hazardous waste per local regulations -- typically as metal-bearing sludge. Fresh water + passivating agent is refilled to the 10 L mark. A full cycle takes 5-10 minutes and requires no tools, only personal protective equipment.
How does the HEPA H14 filter interact with the liquid bath?
The neutralisation bath inactivates dust at the moment of collection, but there will always be a fine aerosol fraction passing the liquid surface. The HEPA H14 filter (cartridge class H13 antistatic polyester) captures 99.995 % of particles down to 0.3 micrometres per EN 1822-5 (MPPS method) before discharge. The combination ensures both safe collection and clean discharge.
