Product Description
Delfin DM2 EL 1/3D is the most powerful model in the 1/3D ATEX series, designed for applications with significant dust loads. With a 2.2 kW motor and 360 m³/h airflow, it extracts three times more air than the MTL301 model, making it ideal for larger production areas and heavy dust generation.
DM2 EL comes equipped with a large star filter (30,000 cm²) and H14 HEPA absolute filter (26,000 cm²), meaning significantly longer service intervals and lower maintenance costs compared to smaller models. The 60 L stainless steel container ensures large collection capacity, and the maintenance-free side channel blower guarantees uninterrupted operation.

DM2 EL Advantages
DM2 EL has several important advantages over smaller models:
- Ø80 mm inlet – Larger connections reduce pressure drop
- Massive filter area – 26,000 cm³ H14 HEPA provides maximum service life
- 60 L collection container – Triple capacity versus MTL301
- 2.2 kW motor – Double power for heavy loads
- Stainless AISI 304 – Durable construction for aggressive dust
Technical Specifications and Certification
DM2 EL 1/3D meets all Zone 20/22 operation requirements with II 1/3D certification, meaning the highest safety level internally (Zone 20) and externally to Zone 22. Rigorous testing to EN 17348:2022 standard ensures the machine will operate reliably in explosive atmospheres.
Frequently Asked Questions
Category 1/3D means the machine's internal part is protected to Zone 20 standard (highest level for dust) while the external part is classified for Zone 22. This provides maximum internal safety.
DM2 EL is the largest model in the 1/3D range with 2.2 kW motor, 360 m³/h airflow, and 60 L collection container. MTL301 has 1.1 kW, 180 m³/h, and 40 L container. DM2 EL features a 26,000 cm³ H14 HEPA filter versus smaller models. DM2 EL is designed for heavier dust loads.
EN 17348:2022 is the harmonized standard for dry-type dust collectors in ATEX areas. It ensures the machine meets all safety requirements for use in explosive atmospheres.
Yes, the side channel blower is maintenance-free and designed for continuous operation without scheduled downtime. The large H14 HEPA filter (26,000 cm³) provides extended service intervals and allows 24/7 operation.
IECEx is the international certification system for explosion-protected equipment. It facilitates approval in countries outside the EU and confirms independent third-party verification of safety and functionality.
DM2 EL is designed for dry combustible dust classified as IIIC (all dust groups including metal dust). The H14 HEPA filter ensures 99.995% particle retention at MPPS.
