Delfin DG VL 75 1/2D
Heavy-duty three-phase ATEX Zone 21 vacuum for continuous industrial use
The Delfin DG VL 75 1/2D is a high-performance industrial vacuum cleaner designed for continuous collection of combustible and conductive dust in Zone 21 and Zone 20. Equipped with a 7.5 kW side channel blower, 160 L stainless steel tank and a fully dust-tight Ex-certified control box, this model is built for multiple operators, long hoses or fixed pipe systems.
- Zone classification: II 1/2D Ex h IIIC T160°C Da/Db.
- Motor: Three-phase 400 V, 7.5 kW – side channel blower with IP65 protection.
- Filter: Antistatic polyester class M and HEPA H14 99.995% (EN 1822, MPPS method).
- Tank: 160 L – AISI 304 stainless steel (standard).
- Automatic SELF CLEAN filter cleaning – ATEX certified.
Technical construction
The DG VL 75 1/2D is equipped with an Ex tb certified control box and a highly efficient filtration system consisting of a primary filter of 70,000 cm² (antistatic polyester) and a HEPA H14 final filter of 52,000 cm². The unit provides up to 2700 mm H₂O vacuum and 700 m³/h airflow. Its 160 L stainless steel tank allows long intervals between maintenance in high-dust environments.
Safety and certification
- ATEX certified Category 1/2D – for internal Zone 20 and external Zone 21.
- All conductive components are fully ESD-safe and grounded.
- IP65-sealed electrical components tested to EN IEC 62784.
- Complies with EN 17348 for combustible dust collection.
Technical note
The DG VL 75 1/2D is engineered for industries with high dust load, extended operating cycles and strict ATEX safety requirements. Typical applications include pharmaceutical, biotech, food and chemical production, often as a central vacuum unit with fixed piping. The SELF CLEAN automatic filter system maintains constant suction without manual cleaning. Always use antistatic or conductive hoses and regularly check grounding resistance below 10⁶ Ω to ensure full ATEX compliance.
