Delfin DG VL 185 PN ACD
ACD industrial vacuum cleaner for combustible dust in non ATEX-classified areas
The Delfin DG VL 185 PN ACD is a powerful three-phase industrial vacuum cleaner designed for the safe collection of combustible and fine dust in ordinary (non-ATEX-classified) areas. The unit is tested according to IEC 60335-2-69 Annex AA (ACD – Applied for Combustible Dust) and equipped with a pneumatic filter cleaning system (PN) with integrated compressor, H14 HEPA filtration, and a fully antistatic filter set. With a 18.5 kW motor, airflow of 1,350 m³/h, and vacuum up to 4,000 mm H₂O, it is ideal for demanding continuous-duty applications.
- ACD classification according to IEC 60335-2-69 Annex AA – for combustible dust handling outside ATEX zones.
- Motor: three-phase 400 V – 18.5 kW – 82 dB(A) – IP65 – maintenance-free side channel blower.
- Filter: 4 × antistatic polyester cartridges (M-class) + HEPA H14 (99.995%).
- Pneumatic PN cleaning during suction – integrated compressor included.
- Container: 160 L – painted steel standard / optional AISI 304 stainless steel.
- Filter surface: 106,000 cm² (primary) + 103,500 cm² (HEPA H14 99.995%).
Technical construction
The DG VL 185 PN ACD is built for heavy-duty 24/7 operation. Its automatic pneumatic cleaning system uses compressed air pulses to clean the filters during suction, maintaining consistent performance and low maintenance. The durable painted steel frame includes forklift intakes and is ideal for fixed installations or integration into central vacuum systems in chemical, metal, or process industries.
Safety and filtration
- Antistatic M-class primary filter and H14 HEPA final filter according to EN 1822-5.
- Pneumatic cleaning (PN) with ATEX-certified components and integrated compressor.
- IP65 motor with thermal protection and pressure relief valve included.
- Low maintenance and high reliability – designed for continuous operation.
