Delfin DG VL 75 ACD

ACD industrial vacuum cleaner for combustible dust in non-ATEX classified areas

The Delfin DG VL 75 ACD is a powerful three-phase industrial vacuum cleaner designed for the safe collection of combustible or hazardous dust in non-ATEX classified areas. It is built in accordance with IEC 60335-2-69 Annex AA and classified as a Class H vacuum cleaner under EN 60335-2-69. The unit features an automatic SELF CLEAN filter system driven by an integrated compressor, and its side-channel blower is rated for continuous operation (24/7).

• Manufactured according to IEC 60335-2-69 Annex AA (ACD standard) and EN 17348.
• H-class vacuum cleaner for combustible and health-hazardous dust.
• Motor: three-phase 400 V – 7.5 kW – IP55 – continuous duty.
• Filter: antistatic polyester M with automatic SELF CLEAN system and final HEPA H14 filter.
• Capacity: 160 L – robust steel container with tangential inlet and cyclonic separation.
• Ideal for stationary or central vacuum systems with long hoses and multiple simultaneous users.

Technical design

The DG VL 75 ACD is powered by a maintenance-free side-channel blower designed for continuous operation and high vacuum performance (4,500 mm H₂O). The primary filter of 70,000 cm² is made of antistatic polyester (Class M) and is automatically cleaned by the SELF CLEAN system. A final HEPA H14 filter (52,000 cm²) tested according to EN 1822-5 ensures 99.995 % efficiency (MPPS method). All conductive components are properly grounded and meet the requirements for combustible-dust handling under EN 17348.

Safety and certification

• ACD-designed 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 intended for ATEX-classified zones, but compliant with leakage and filtration requirements for combustible dust in ordinary environments.
• Equipped with HEPA H14 filter (99.995 % efficiency, EN 1822-5).
• Automatic SELF CLEAN filter cleaning with integrated compressor.

Technical note

The Delfin ACD series is intended for the safe collection of combustible or toxic dust in non-classified areas where ATEX certification is not required. The design follows IEC 60335-2-69 Annex AA, defining strict requirements for containment, filtration efficiency, and leakage control. The DG VL 75 ACD is often used as part of central vacuum systems in the chemical, plastic, or metal-processing industries where the dust itself is combustible but the surrounding atmosphere is non-explosive.

FAQ

What does ACD classification mean?
ACD stands for Applied for Combustible Dust. It indicates that the vacuum cleaner is built according to IEC 60335-2-69 Annex AA and meets the requirements for containment, filtration, and safe handling of combustible dust in non-ATEX areas.

Is the Delfin DG VL 75 ACD third-party tested?
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 it 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 units are intended for general industrial use where the dust is combustible but the atmosphere is non-explosive. For Zone 22 applications, choose a 1/3D model instead.

How is the filter cleaned?
By the automatic SELF CLEAN system with internal compressor that cleans the filter during operation.
