Key Technical Specifications Explained

Rather than listing technical data without context, here’s what the specifications actually mean for your operation:

ATEX Zone 20 (Internal) & Zone 22 (External)

Zone 20 internal certification means explosive dust atmospheres may be present continuously inside the vacuum system itself.
Zone 22 external certification means the surrounding environment may occasionally contain explosive dust clouds.

This dual certification ensures both the machine’s interior and exterior are designed to prevent ignition.

Two-Stage Filtration System (Class M + HEPA 99.995%)

The vacuum uses:

A Class M antistatic primary filter, capturing the majority of fine dust.
A HEPA absolute filter (99.995% efficiency), preventing microscopic particles from re-entering the workspace.

This is critical in pharmaceutical, food, and precision manufacturing environments where air purity and worker safety are non-negotiable.

Bypass Motor (For Non-Continuous Use)

The MTL301 is powered by a bypass motor, making it ideal for:

Maintenance tasks
Intermittent cleaning
Scheduled housekeeping

It is not intended for 24/7 continuous duty, but excels in portable, flexible deployment across departments.

Stainless Steel AISI 304 Collection Tank

The collection container is:

Corrosion-resistant
Easy to sanitise
Durable in industrial environments

This makes it particularly suitable for food, pharma, and chemical sectors.

Anti-Static & Grounding System

Built-in earth grounding and anti-static components prevent electrostatic discharge, a critical ignition source in combustible dust environments.

Why Choose the Delfin MTL301 1/3D Over Alternatives?

Many industrial vacuum cleaners claim ATEX compliance. Few provide the balance of true Zone 20 internal certification, HEPA-level filtration, compact mobility, and cost-efficiency that this model delivers.

Compared to larger continuous-duty ATEX systems, the MTL301 offers:

Lower capital cost
Greater portability
Easier manoeuvrability in tight production areas
Faster deployment for maintenance teams
Simplified filter replacement and servicing

If you require a compact explosion-proof vacuum for intermittent hazardous cleaning, rather than a fixed centralised extraction system, this model represents a highly practical and compliant solution.

It bridges the gap between heavy-duty industrial vacuum systems and portable shop-style units, without compromising safety certification.

Frequently Asked Questions (FAQs)

What does ATEX Zone 20 and Zone 22 mean?

Zone 20 refers to areas where explosive dust is present continuously or frequently inside equipment. Zone 22 refers to areas where explosive dust atmospheres are unlikely during normal operation but may occur occasionally. The MTL301 is certified for both internally and externally.

Is this vacuum suitable for combustible dust?

Yes. It is specifically engineered for combustible dust and fine particulates in medium-risk explosion zones.

Can this vacuum run continuously?

No. The bypass motor is designed for non-continuous or intermittent use. For continuous duty applications, a turbine-powered ATEX model would be more suitable.

Does it include HEPA filtration?

Yes. It features a HEPA absolute filter rated at 99.995% efficiency, ideal for fine and hazardous dust.

Which industries commonly use this model?

Pharmaceutical, food production, chemical processing, metalworking, and any sector managing explosive dust risk.

Is it portable?

Yes. It is compact, mobile, and easy to manoeuvre, making it ideal for maintenance teams working across multiple areas.
