Delfin MTL 202 ACD 1/-D
ACD vacuum cleaner for combustible and toxic dust – compact and stainless steel
The Delfin MTL 202 ACD is a compact single-phase industrial vacuum cleaner designed for the safe collection of combustible, conductive, or toxic dust in non-classified areas. It complies with IEC 60335-2-69 (Annex AA) for ACD (Applied for Combustible Dust) vacuum cleaners, making it ideal where ATEX certification is not required but tightness, filtration, and operator safety are still critical.
- ACD classification: II 1/-D Ex h IIIC T80°C (Internal) Da/-.
- Motor: single-phase 230 V – 2.2 kW – low noise level 74 dB(A).
- Filter: antistatic polyester M-class with Dustop cleaning + HEPA H14 final filter.
- Container: 20 L AISI 304 stainless steel with tangential inlet and integrated cyclone.
Technical design
The vacuum has a tangential inlet with an integrated cyclone that protects the filter and maintains a stable airflow. The primary filter of 30,000 cm² is made of antistatic polyester (M-class) and cleaned by the mechanical Dustop system. A HEPA H14 filter with a surface of 20,500 cm² captures fine particles with 99.995 % efficiency according to EN 1822-5 (MPPS method).
Safety and classification
- ACD certified according to IEC 60335-2-69 (Annex AA).
- Meets leakage-tightness, filtration, and containment requirements for toxic or conductive dust.
- Filter housing and container in AISI 304 – ESD-safe components and conductive accessories included.
- For use in non-classified environments where explosion risk is absent but dust containment is critical.
Technical note
ACD models bridge the gap between standard industrial vacuums and fully ATEX-certified units. The Delfin MTL 202 ACD is built on the same platform as the ATEX models but certified under IEC 60335-2-69 (Annex AA), ensuring complete tightness, advanced filtration, and safe containment of hazardous or conductive dust. This makes it suitable for laboratories, pharmaceutical production, metalworking, and quality-controlled environments without explosive atmospheres.

FAQ
What does ACD mean?
ACD stands for Applied for Combustible Dust and is an IEC classification under IEC 60335-2-69 Annex AA for vacuum cleaners designed to handle hazardous or conductive dust in non-classified areas.
Can it collect combustible dust?
Yes – but only in non-classified areas. For Zone 21 or 22, an ATEX-certified vacuum is required.
Is it made of stainless steel?
Yes, both the container and filter housing are made of AISI 304 stainless steel.
How is the filter cleaned?
By the mechanical Dustop system – no compressed air and no dust emission.
Which filter class does it have?
HEPA H14 with 99.995 % efficiency (EN 1822-5 MPPS method).
