Features and Technology
Delfin DM2 EL 1/2D ATEX is a robust mobile dust collector designed for permanent installation or portable operation in ATEX Zone 21 areas (and Zone 20 internal). Zone 21 means explosive combustible dust atmospheres may occur 10-1,000 hours per year under normal operating conditions, requiring robust and certified design. The machine is third-party certified by IMQ per EN 17348 DT (Dry Type Dust Collector) and EU Directive 2014/34/EU as category 1/2D, meaning it is approved for combustible dust (dust zones 20/21).
The single-phase vacuum motor is designed as a dust-tight IP64 enclosure (Ex tb) for maximum safety in hazardous areas. Manual filter cleaning means the H14 HEPA filter is cleaned by physical tapping or squeezing without complex electric mechanisms, reducing maintenance requirements and ensuring reliability. The 100 L collection tank in stainless steel AISI304 provides significantly greater capacity than smaller models. 430 m³/h airflow and 2,250 mmH₂O maximum vacuum make the DM2 EL 1/2D suitable for mobile dust collection tasks in industrial processes, pharma, chemicals, and explosive dust silos.
The ESD accessory kit (TA.1305.0000) is included as standard, ensuring electrostatic grounding in ATEX-certified areas. Robust design and simple mechanisms make the machine ideal for field use without specialized technicians.

Frequently Asked Questions
ATEX Zone 21 means explosive combustible dust atmospheres may occur 10-1,000 hours per year under normal operating conditions. Zone 21 is higher risk than Zone 22 and requires robust, certified design. DM2 EL 1/2D is a mobile dust collector specifically designed for Zone 21 applications.
II 1/2D means the machine is certified for combustible dust-explosive atmospheres (combustible dust only, not gases). This classification ensures the highest safety level for Zone 20/21 operation. DM2 EL 1/2D is specifically designed and certified for ATEX dust zones.
A 100 L tank provides significantly greater capacity than smaller vacuum cleaners, meaning less frequent emptying, higher productivity, and reduced maintenance needs. Ideal for aggressive dust types and continuous operation in industrial processes.
Yes. The H14 HEPA absolute filter is included as standard. It ensures 99.995% particle retention at MPPS (Most Penetrating Particle Size), providing maximum air and environmental protection even at very high dust concentrations.
Yes. DM2 EL 1/2D is third-party certified by IMQ (accredited notified body). You receive full EU documentation, original certification, and technical file confirming Zone 21 classification.
Manual filter cleaning means the H14 HEPA filter is cleaned by physically tapping or squeezing it by hand without an electric mechanism. This reduces complexity, maintenance requirements, and power consumption, making it ideal for mobile vacuum cleaners in hazardous ATEX areas.
