Introduction – Why Industrial Vacuum Safety Matters
In industries like pharmaceuticals, food processing, chemical manufacturing, and metalworking, explosive and combustible dust is a constant hazard. A single spark or improper cleaning method can lead to catastrophic incidents. This is where ATEX-certified industrial vacuum cleaners, particularly from Delfin, play a crucial role—and why CleaningMachines.ie places them at the forefront of its safety-first approach.
According to Delfin’s product line, their units are equipped with antistatic class M filters, stainless steel containers, and grounding as standard features. All components—from turbines to electrical panels—are tested and certified by accredited third parties to comply with ATEX Zone 22 requirements and beyond [1].
What is ATEX? – Navigating Regulations and Zones
ATEX—stemming from EU directives 94/9/EC and 2014/34/EU—regulates equipment designed for explosive atmospheres. It classifies environments using two categories:
- Dust zones: Zone 20 (high risk), 21 (intermediate), 22 (occasional risk)
- Gas zones: Zone 0, 1, 2
Delfin’s line spans Zones 20 through 22 (dust) and Zones 2 through 22 (gas/dust). These certifications are supported by IECEx adherence and rigorous third-party testing, providing a clear safety pathway for industries dealing with combustible materials [1][2].
At CleaningMachines.ie, this compliance isn’t just about products—it’s about protecting people, assets, and your reputation. Offering certified machines ensures that every vacuum you use meets HSA, COSHH, and EPA standards in Ireland.

Delfin’s ATEX Product Range – Models Built to Withstand Extremes
1. Compact Zone 22 Units – Delfin BL 300 3D
A compact single-phase vacuum, the BL 300 3D features a brushless head, fully stainless steel container (AISI 304), antistatic filter, and grounding—perfect for occasional dusty environments [3].
2. Portable Air-Operated Units – AIR DM 19 V & DM 3
Compressed-air driven, these models use multi-jet Venturi systems for continuous, maintenance-free suction—ideal for zones where electricity isn’t permitted. The AIR DM 19 V is compact, efficient, and also ATEX Zone 22-approved [4].
3. Heavy-Duty Wheelable Units – DG EXP Series
Built for Zones 20/21/22, these three-phase stainless steel vacuums feature side-channel blowers, large filters with manual shaking, detachable tanks, vacuum gauges, and optional HEPA filtration—all mounted on wheels for portability [2].
4. Inert Bath & Spark-Free Units
Models like Mistral 451 BL use inert fluid baths and spark-free brushless motors for highly reactive dusts, boosting operator safety and extending motor life to 15,000 hours [8].

🛠️ Core Safety & Design Features
- Antistatic Class M Filters: Minimize ignition risk; paired with HEPA filters for fine particles
- Stainless Steel Construction: Durable and safe in harsh environments
- Grounding & Spark-Free Motors: Remove ignition sources by design
- Brushless, Side-Channel Blowers: Low maintenance, continuous duty, ATEX approved
- Integrated Filter Management: Manual shaking and vacuum-based clog detection via gauge
These elements exceed standard compliance by offering performance, safety, and ease-of-use under industrial stress [1][2][18].
🏭 Industrial Applications – Where Delfin Excels
Delfin DG 70 EXP Z22, a wheelable unit, excels in food, cement, ceramics, chemical, and plastic industries. Its large stainless steel collection tank, vacuum gauge, and HEPA options make it ideal for lifting fine and hazardous dust [6].
The air-driven DM 19 V thrives in environments with flammable dust or where electrical power is limited (e.g., grain silos, paint booths) [4].
Compact units like BL 300 3D are perfect for workshops needing spot-cleaning in Zone 22 areas [3].
🧾 Compliance & Safety Benefits for Your Business
Using ATEX-compliant vacuums underpins compliance with Irish/EU laws, safeguarding:
- Workers from health risks caused by dust exposure
- Sites from regulatory penalties under COSHH
- Assets and reputation from potential explosion incidents
Moreover, insurance premiums often decrease when documented safety practices (like ATEX vacuum usage) are in place.
💰 ROI & Cost Justification
Investing in a proper ATEX vacuum brings value in:
- Reduced cleanup downtime with efficient dust removal
- Compliance risk management avoiding fines
- Low operating costs from durable brushless motors
- Long operational life and reconditioning longevity
When compared with incident costs, ATEX vacuums are both economical and prudent.
