Features and Technology
The Delfin MTL 301 1/2D ATEX is a compact mobile dust collector designed for permanent installation in ATEX Zone 21 environments. Zone 21 means explosive dust-air mixtures may occur 10–1,000 hours per year — higher risk than Zone 22 and requiring more robust construction. The unit is third-party certified per EN 17348 (DT — dry type dust collector) and EU Directive 2014/34/EU as category 1/2D, meaning it is approved for Zone 20 internal and Zone 21 external dust collection.
The single-phase vacuum motor with IP64-rated vacuum head provides robust and reliable operation without complex three-phase electrical requirements. The H14 HEPA filter ensures 99.995% particle retention at MPPS (Most Penetrating Particle Size) even at very high dust concentrations. Stainless steel AISI304 as standard ensures maximum corrosion resistance in aggressive industrial environments.
The 40 L collection vessel provides good capacity for many dust applications. Airflow of 215 m³/h and maximum vacuum of 2,250 mmH₂O make the MTL 301 1/2D suitable for medium-scale industrial processes, hazardous dust collection, and flexible deployment across different work sites. Compact form factor (only 26 kg) makes it easily transportable between locations.

Frequently Asked Questions
ATEX Zone 21 means explosive dust-air mixtures can occur 10–1,000 hours per year under normal operating conditions. This is higher risk than Zone 22 and requires more robust and certified construction. The MTL 301 1/2D ATEX is a compact mobile Zone 21 collector — certified for hazardous dust environments.
II 1/2D means the equipment is certified for the highest ATEX safety category 1/2 for both Zone 1 (explosive gases) and Zone 21 (explosive dusts). For dust collectors, this means the unit can be used in highly aggressive dust environments with robust construction, ESD-safe materials, and H14 HEPA filter as standard.
Yes. The MTL 301 1/2D ATEX is third-party certified by IMQ, an accredited notified body (European authority) under EU Directive 2014/34/EU. You receive full EU documentation, certification, and technical file confirming Zone 21 and II 1/2D classification. Installation should be performed per ATEX guidelines.
The H14 HEPA filter (High Efficiency Particulate Air) ensures 99.995% filtration efficiency at MPPS (Most Penetrating Particle Size). This means safe particle collection even at very high dust concentrations — critical for Zone 21 applications. The MTL 301 1/2D includes H14 as standard at no extra cost, with 11,000 cm² filter area.
The disposable antistatic filter bag (class M) provides safe and hygienic dust handling without risk of cross-contamination or manual emptying. The bag seals all collected dust until final disposal, making it ideal for hazardous or aggressive dust types. Perfect for Zone 21 applications where safety is paramount.
Standard accessories include the TA.0527.0000 kit with ESD-safe hoses and adapters for Zone 21 operation. Options: antistatic disposable filter bag class M (FI.0469.0000) for extra safety with hazardous dust types. Contact us for other specialized configurations or volume inquiries.
The MTL 301 1/2D is certified for higher-risk Zone 21 (versus Zone 22) with robust single-phase motor, IP64 vacuum head, H14 HEPA filter, and stainless steel AISI304. The compact mobile form factor (26 kg) makes it flexible for different work sites, whereas Zone 22 models are typically stationary. Choose Zone 21 certification for hazardous dust environments.
