Features and Technology
The Delfin MTL201 1/2D ATEX is a compact mobile vacuum designed for ATEX Zone 21 and Zone 20 dust areas. This size is ideal for smaller facilities, mobile work sites, and applications where space and flexibility are important. The machine is third-party certified per EN 17348:2022 and EU Directive 2014/34/EU as category 1/2D, which means it is approved exclusively for dust zones, not gas areas or mixed atmospheres.
The tangential inlet with integrated cyclone creates natural dust separation at the inlet point. Heavy dust is immediately separated and drops to the bottom of the collection container, while only clean air passes through the H14 HEPA filter. This significantly reduces filter loading, extends filter service life, and reduces noise level to 74 dB(A).
The Dustop system is an integrated automatic filter cleaning system that continuously pulses compressed air through the filter. This improves filter performance, reduces maintenance requirements, and enables longer operating periods between filter replacements. The H14 HEPA filter guarantees 99.995% particle retention at MPPS even at very high dust concentrations. Stainless steel AISI304 as standard ensures maximum corrosion resistance in aggressive industrial environments. The ESD accessory kit is included for safe handling of electrostatic-sensitive dust.

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. It is a higher risk level than Zone 22 and requires stronger and more robust construction. MTL201 1/2D is certified for both Zone 20 (internal) and Zone 21 (external) operation, making it very flexible for different areas.
II 1/2D means the machine is certified to ATEX Category 1/2D at the highest safety level. D specifically refers to dust zone certification. MTL201 1/2D is designed exclusively for dust-explosive atmospheres in Zone 20 (internal) and Zone 21 (external). It automatically covers Zone 22 as well.
Dustop is an integrated automatic filter cleaning system that continuously pulses compressed air through the H14 HEPA filter. This process cleans the filter surface and reduces dust accumulation. Dustop significantly extends filter service life, reduces maintenance requirements, and enables longer operating periods between filter replacements.
H14 HEPA is the highest absolute filter classification. It guarantees 99.995% particle retention at MPPS (Most Penetrating Particle Size). This means even very fine and dangerous dust particles (including metal dust, pharmaceutical dust, and chemical powders) are filtered. H14 HEPA ensures extremely clean exhaust air even at very high dust concentrations.
Tangential inlet means dust enters sideways (tangentially) into the collection container, creating a natural cyclone effect at the inlet point. Heavy dust is centrifuged and falls immediately to the bottom, while only clean air passes upward to the filter. This significantly reduces filter loading, minimizes maintenance, and reduces noise level.
Yes. MTL201 1/2D ATEX is third-party certified by IMQ, an accredited notified body under ATEX Directive 2014/34/EU. You receive complete EU documentation, technical file, IECEx certification (Da/Db), and original certification confirming Zone 20/21 classification per EN 17348:2022. Installation must be performed per ATEX guidelines.
