Delfin DG VL 125 1/2D
Extremely powerful ATEX Zone 21 vacuum for continuous and centralised operation
The Delfin DG VL 125 1/2D is a heavy-duty three-phase industrial vacuum designed for demanding process environments with high dust loads, long hose runs and multiple operators. Equipped with a 18.5 kW side channel blower, 160 L stainless steel tank and a fully ATEX-certified control system, it is ideal for central vacuum installations in production areas classified as Zone 21 or internal Zone 20.
- Zone classification: II 1/2D Ex h IIIC T160°C Da/Db.
- Motor: Three-phase 400 V – 18.5 kW side-channel blower (IP65).
- Filters: Antistatic polyester class M + HEPA H14 (99.995 % at 0.3 µm, EN 1822 MPPS method).
- Tank: 160 L AISI 304 stainless steel (standard).
- Automatic SELF CLEAN filter cleaning system (ATEX approved).
Technical construction
The DG VL 125 1/2D features an Ex tb certified control panel and a high-efficiency filtration system with a 70 000 cm² primary antistatic filter and a HEPA H14 final filter of 103 500 cm².
It delivers up to 3100 mm H₂O vacuum and 1100 m³/h airflow.
The combination of high suction power, large filter area and 160 L tank makes this unit perfect for continuous operation and fixed installations.
Safety and certification
- ATEX Category 1/2D – internal Zone 20 and external Zone 21.
- All conductive components are ESD-safe and grounded.
- IP65-sealed electrical components tested according to EN IEC 62784.
- Complies with EN 17348 and EN 1822 for combustible dust and HEPA filtration.
Technical note
The DG VL 125 1/2D represents the top of the Delfin ATEX range.
It is engineered for central vacuum systems in pharmaceutical, biotech, food and chemical industries, where continuous operation, safety and hygiene are critical.
The SELF CLEAN system automatically cleans the filter without compressed air, maintaining constant suction during long production cycles.
For full ATEX compliance, always use antistatic or conductive hoses and accessories and verify grounding resistance below 10⁶ Ω regularly.
