Delfin MTL 202 1/2D LP
ATEX Zone 21 vacuum with Longopac ESD – dust-free and safe collection of combustible dust
The Delfin MTL 202 1/2D LP is a compact and robust ATEX-certified industrial vacuum cleaner designed for the safe collection of combustible dust in Zone 21 areas. It features the Longopac ESD (antistatic) endless bagging system that enables dust-free, fast, and hygienic waste handling. The container and filter housing are made of AISI 304 stainless steel, and the filtration system meets EN 1822 (H14) and IEC 60335-2-69 standards.
- Zone classification: II 1/2D Ex h tb IIIC T80°C (Int) / T95°C (Ext) Da/Db.
- Motor: single-phase 115/230 V – 1.1 kW – low noise level 74 dB(A).
- Filter: antistatic polyester M-class with Dustop cleaning + HEPA H14 final filter.
- Longopac ESD: antistatic endless bag – dust-free and flexible waste handling.
- Supplied with antistatic accessory kit TA.0527.0000 (D40 mm).
Technical design
The tangential inlet with integrated cyclone reduces filter load and maintains a stable airflow (215 m³/h). The primary filter of 30,000 cm² (antistatic polyester, M-class) is cleaned mechanically by the Dustop system. The final HEPA H14 filter of 26,000 cm² captures fine dust particles with 99.995 % efficiency (MPPS method). All conductive parts are ESD-safe.
Safety and certification
- ATEX marking: II 1/2D Ex h tb IIIC T80°C (Int) / T95°C (Ext) Da/Db.
- Zone 20 inside (filter and container), Zone 21 outside on surfaces and surroundings.
- Complies with EN 17348, EN IEC 62784 and IEC 60335-2-69.
- All main parts in AISI 304 stainless steel with conductive and antistatic accessories.
Technical note
The Delfin MTL 202 1/2D LP is designed for safe collection of combustible dust directly into the Longopac ESD bag, where explosive atmospheres can occur inside (Zone 20) and around the unit (Zone 21). It combines Dustop cleaning and H14 filtration with a dust-free Longopac ESD system, eliminating exposure during emptying. Always use antistatic accessories and maintain grounding resistance below 10⁶ Ω to ensure full compliance and operator protection.

FAQ
What does II 1/2D (Da/Db) mean?
It indicates certification for Zone 20 inside the vacuum and Zone 21 on external surfaces – ensuring safe collection of combustible dust.
What are the advantages of Longopac ESD?
The antistatic Longopac system provides dust-free waste handling with no contact to the collected dust, variable bag length, and quick sealing – ideal for controlled environments.
How is the filter cleaned?
Via the Dustop mechanical cleaning system – no compressed air and no dust emissions.
What is included in the TA.0527.0000 (D40) kit?
3 m antistatic hose, stainless-steel tubes (straight + curved), couplings, conical rubber nozzle, antistatic brush, and dry floor nozzle.
Can it be used in food or pharmaceutical production?
Yes – all contact parts are made of AISI 304 stainless steel, ensuring hygiene and low contamination risk.
