Delfin DG VL 185 ACD
ACD industrial vacuum cleaner for combustible dust in non-ATEX classified areas
The Delfin DG VL 185 ACD is a powerful three-phase industrial vacuum cleaner equipped with an 18.5 kW side-channel blower designed for continuous operation (24/7) and the safe collection of combustible or hazardous dust in non-ATEX classified areas. It is built according to IEC 60335-2-69 Annex AA and classified as a Class H vacuum cleaner under EN 60335-2-69. With a large filter surface and automatic SELF CLEAN system, it is ideal for use as a central vacuum in heavy-duty industrial environments.
- Manufactured according to IEC 60335-2-69 Annex AA (ACD standard) and EN 17348.
- H-class vacuum cleaner for combustible and hazardous dust.
- Motor: three-phase 400 V – 18.5 kW – IP55 – continuous duty.
- Filter: antistatic polyester M with automatic SELF CLEAN system and final HEPA H14 filter.
- Container: 160 L steel tank with tangential inlet and cyclonic separation.
- Ideal for large central vacuum systems with long hoses and multiple simultaneous users.
Technical design
The DG VL 185 ACD is powered by a high-performance side-channel blower providing a maximum vacuum of 5,500 mm H₂O and an airflow of 1,050 m³/h. The primary filter of 90,000 cm² is made of antistatic polyester (Class M) and is automatically cleaned by the SELF CLEAN system with an internal compressor. The final HEPA H14 filter (52,000 cm²) is tested according to EN 1822-5 with 99.995 % efficiency (MPPS method). All conductive components are properly grounded according to EN 17348.
Safety and certification
- ACD-built according to IEC 60335-2-69 Annex AA and EN 17348.
- Certified as a Class H vacuum cleaner (EN 60335-2-69 Annex AA).
- Not ATEX-certified – suitable for ordinary industrial environments with combustible dust.
- Equipped with HEPA H14 final filter (99.995 % efficiency, EN 1822-5).
- Automatic SELF CLEAN system with integrated compressor.
Technical note
The Delfin DG VL 185 ACD is designed for heavy-duty industries such as chemical production, powder processing, and metalworking, where dust can be combustible or hazardous but the surrounding atmosphere is non-explosive. The unit meets the requirements of IEC 60335-2-69 Annex AA and EN 17348 for filtration, containment, and controlled dust discharge. It is ideal for central vacuum systems or fixed installations with multiple users and long piping networks.

FAQ
What does ACD classification mean?
ACD stands for Applied for Combustible Dust and indicates that the vacuum cleaner is built according to IEC 60335-2-69 Annex AA, meeting requirements for containment, filtration, and safe handling of combustible dust in non-ATEX classified areas.
Is the Delfin DG VL 185 ACD third-party certified?
No. The model is not third-party certified, but Delfin declares conformity with IEC 60335-2-69 Annex AA and EN 17348.
What filter class does the vacuum have?
Primary filter in antistatic polyester M and final HEPA H14 (99.995 % efficiency, EN 1822-5).
Can it be used in Zone 22?
No. ACD models are designed for areas where dust is combustible but the atmosphere is non-explosive. For Zone 22, choose a 1/3D model.
How is the filter cleaned?
Through the SELF CLEAN system with internal compressor that automatically cleans the filter during operation.
