Features and Technology

The Delfin DM2 EL 1/2D LP is a stationary vacuum cleaner designed for permanent installation in ATEX Zone 21 areas. Zone 21 means explosive dust-air mixtures can occur 10-1,000 hours per year under normal operating conditions—higher risk than Zone 22 and requiring more robust construction. The machine is third-party certified by IMQ per EN 17348 DT and EU Directive 2014/34/EU as category 1/2D, approved for explosive dust-air atmospheres.

The Longopac system is the central innovation of this machine. Endless bags in 20 meters of continuous length remove dust completely without opening the collection container. When the bag is full, it is simply pulled from the machine without operator dust exposure. This is crucial for work environment safety in aggressive dust areas, pharmaceutical and cleanroom production.

The single-phase 2.2 kW vacuum motor with Ex tb dust tight IP64-classified vacuum head ensures maximum safety. The H14 HEPA filter with 99.995% particle retention at MPPS ensures extremely high purity. At 430 m³/h airflow and 2,250 mmH₂O maximum vacuum, the DM2 EL 1/2D LP is suitable for large-scale industrial processes, silo and process outlet cleaning, and continuous collection without operator exposure.

Zone 21 certification and dust-free emptying: This unit is third-party certified by IMQ for Zone 21 operation. The Longopac system ensures dust-free emptying. Category 1/2D means higher safety level. You receive full EU documentation, technical file, and IECEx certification. Installation must be performed per ATEX guidelines. Includes accessory kit TA.1305.0000.

Frequently Asked Questions

ATEX Zone 21 means the machine is certified for permanent installation in areas where explosive dust-air mixtures can occur 10-1,000 hours per year under normal operating conditions. Zone 21 represents higher risk than Zone 22 and requires more robust and certified construction. The DM2 EL 1/2D LP is one of the few vacuum cleaners with this high classification.

Longopac endless bags are a unique emptying system that contains dust completely without opening the collection container. When the bag is full, it is simply pulled from the machine without the operator coming into contact with dust. On this DM2 EL, there is 20 meters of continuous bag material, providing large capacity with minimal downtime for emptying.

The Longopac system surrounds dust completely and automatically seals it without opening the collection container. The operator simply pulls the bag from the machine without dust exposure. This means maximum safety for the work environment and no dust cleaning or container scrubbing required.

H14 HEPA is the highest HEPA filtration level with 99.995% particle retention at MPPS (Most Penetrating Particle Size). This filter is standard included on the DM2 EL 1/2D LP and ensures extremely high purity. It is ideal for pharmaceutical, cleanroom, and very fine dust applications.

Yes. The DM2 EL 1/2D LP is third-party certified by IMQ, an accredited notified body under EU ATEX Directive 2014/34/EU. You receive full EU documentation, IECEx certification for Zone 21 (Da/Db), and technical file. Installation must be performed according to ATEX guidelines.

The DM2 EL 1/2D LP protects the operator through multiple mechanisms: Longopac endless bags remove dust without opening the container, IP64 vacuum head with Ex tb dust tight classification, H14 HEPA filter for 99.995% purity, and 2.2 kW single-phase motor. Dust is completely sealed away from humans.

The DM2 EL 1/2D LP is ATEX Zone 21 certified (standard DM2 EL is not), has Longopac endless bags with dust-free emptying, larger capacity (20 m vs smaller), third-party certified by IMQ, and designed for aggressive dust environments with high safety requirements. Choose the LP version for high exposure and Zone 21 certification.
