Delfin MTL301 BP 1/3D
Professional ATEX vacuum cleaner for daily shooting range maintenance
The Delfin MTL301 BP 1/3D is designed for daily cleaning of firing halls, locker rooms, and corridors in indoor shooting ranges. With certified H14 HEPA filtration and ATEX marking II 1/3D, it safely removes lead and gunpowder dust in full compliance with the latest EU occupational safety requirements.
Certified safety instead of self-declared
Self-declared solutions place the burden of zone classification on you. The MTL301 BP 1/3D is marked II 1/3D Ex h tb IIIC, approved for internal Zone 20 and external Zone 22 (Da/Dc). The collection unit is made of AISI304 stainless steel and fitted with an antistatic primary filter and H14 final stage according to EN 1822.
Why ordinary vacuum cleaners make things worse
The EU lead exposure limit of 0.03 mg/m³ is frequently exceeded on shooting ranges. Ordinary vacuum cleaners recirculate fine lead particles back into the air, increasing exposure – and without explosion-proof design, gunpowder residues may ignite. This is why HEPA-filtered equipment certified for combustible dust is essential.
Complete protection
H14 HEPA filter (99.995% efficiency at MPPS) as the final stage; antistatic M-class primary filter; continuous ESD-safe chain with conductive accessories; compact and mobile 40 L stainless steel system built for intensive daily use.
Applications
ATEX-certified areas (Z22 operation, internal Z20 in container):
- Firing halls (daily housekeeping)
- Gun cleaning rooms and technical dust zones
- Planned overhead cleaning (rails/ducts) with antistatic kit
HEPA-filtered areas (non-ATEX):
- Locker rooms and exit zones (prevent “take-home lead”)
- Corridors with shooting range traffic
- Ammunition depots and support areas
