Nilfisk ATTIX 791-2M/B1 Type 22 ATEX Zone 22 M-Class Industrial Vac...
Nilfisk ATTIX 791-2M/B1 Type 22 ATEX Zone 22 M-Class Industrial Vacuum Cleaner (70L)
The Nilfisk ATTIX 791-2M/B1 Type 22 is an industrial wet/dry vacuum cleaner engineered specifically for extracting hazardous and combustible dusts in certified ATEX Zone 22 environments. Powered by a brushless, single-phase EC motor and certified to ATEX Directive 2014/34/EU and dust class M, this unit provides ignition-source-free collection of explosive airborne particles, metal grindings, flour, starch, wood dust, and pharmaceutical powders.
Featuring a heavy-duty 70-litre corrosion-resistant stainless steel container mounted on a tilt-or-lift chassis, the ATTIX 791-2M/B1 delivers high capacity for demanding manufacturing and production facilities. Its integrated FlowSensor monitoring system continuously tracks air velocity in the suction hose, emitting an audible and visual acoustic warning if airflow drops below the legal safety threshold of 20 m/s—ensuring compliance with HSE COSHH extraction standards.
Key Features & Operational Benefits
- Certified ATEX Zone 22 Compliance: Fully approved for use in environments where explosive atmospheres caused by combustible dust clouds are expected to occur occasionally during normal operations.
- M-Class Filtration Standard: Certified to Dust Class M (EN 60335-2-69) to safely capture medium-risk hazardous dusts with workplace exposure limits (WEL) greater than 0.1 mg/m³ at 99.9% filtration efficiency.
- Spark-Free Brushless EC Motor: Electronically commutated (EC) single-phase motor eliminates carbon brushes, preventing electrical arcing, lowering operating temperatures, and extending operational life.
- Massive 70L Stainless Steel Container: Industrial-grade stainless steel drum resists abrasive dusts and chemical attack while reducing disposal frequency during heavy shifts.
- Tilt & Lift-Out Disposal Chassis: The robust tubular steel trolley allows operators to tilt the 70-litre drum to empty waste into floor skips, or lift the container out entirely via built-in carry handles.
- Active FlowSensor Airflow Alarm: Real-time acoustic safety alarm alerts the operator immediately if the filter is blocked or airflow drops below 20 m/s.
- Full Anti-Static Earthing: Completely conductive construction directs static charges safely to earth through the conductive hose connection and earthed power lead, preventing dangerous electrostatic discharge.
- Auto-On/Off Tool Socket: Built-in power take-off socket enables automatic remote start/stop synchronisation when connected to portable electric power tools.
Supply Scope & Recommended Accessories
⚠️ Important Package Notice:
The Nilfisk ATTIX 791-2M/B1 Type 22 is supplied as a bare base machine with 1x 3.5m Type 22 anti-static suction hose only. Floor nozzles, extension tubes, hand tools, and dust bags are not included with the standard machine head and must be ordered separately.
1. Essential Conductive Tooling Kit:
To ensure immediate readiness and maintain full ATEX Zone 22 safety compliance, pair the machine with its dedicated conductive tooling set:
👉 [Nilfisk TYPE 22 VACUUM SET Ø36MM 6-PCS (Part No. 48907)]
A specialist 6-piece conductive accessory kit engineered specifically for ATEX Zone 22 certified vacuums.Manufactured from static-dissipative polymer and aluminium components, it includes:
- 1 x Bent Hand Tube (conductive)
- 1 x Extension Tube (conductive)
- 1 x Professional Floor Nozzle (wet/dry interchangeable)
- 1 x Crevice Nozzle (conductive)
- 1 x Brush Nozzle
2. Recommended Dust Containment & Machine Longevity:
For clean disposal and critical primary motor protection inside the 70-litre drum, choose from genuine Nilfisk containment bags based on your hazard profile:
[Nilfisk SAFETY FILTER BAG M ATTIX/IVB 7 5 PCS (Part No. 302001486)]
Recommended for certified M-Class hazardous dust extraction and maximum operator safety.
Engineered specifically for the 70L ATTIX/IVB 7 chassis, these heavy-duty safety filter bags feature a dual-layer design combining a high-efficiency fleece inner liner with an outer plastic encapsulation sack and an integrated slide-seal closure. They allow operators to remove and seal medium-risk, carcinogenic, or toxic combustible dusts completely dust-free, preventing secondary contamination of the workspace during disposal.
[Nilfisk FLEECE FILTER BAG PU 5 PCS (Part No. 302002892)]
Recommended for general combustible particulate collection (wood dust, flour, grain).
Multi-layer synthetic fleece bags that act as a high-performance primary barrier. They prevent the main washable PET filter cartridge from blinding, maintain consistent airflow velocity above 20 m/s, and extend the operating life of the brushless EC motor.
Applications & Industry Suitability
The Nilfisk ATTIX 791-2M/B1 Type 22 is engineered for production facilities handling flammable, combustible, or fine hazardous powders:
- Food Processing & Bakeries: Flour, starch, cocoa, sugar, and dried spice dust handling.
- Woodworking & Joinery: Fine combustible sawdust, sanding dust, and MDF particle extraction.
- Pharmaceutical & Chemical Production: Bulk ingredient transfer, pill pressing areas, and powder compaction cleanup.

- Plastics & Biomass Processing: Extrusion lines, pellet handling, and combustible agricultural waste management.
Understanding ATEX Vacuum Cleaners: Explosion Safety & Compliance Explained
In industrial environments where combustible dusts, powders, or flammable vapors are present—such as chemical plants, grain silos, and advanced manufacturing hubs—standard vacuum cleaners pose a severe ignition risk. This is where ATEX-certified vacuum cleaners become a legal and life-saving necessity.
What is an ATEX Vacuum Cleaner?
ATEX (Atmosphères Explosibles) is a mandatory European and UK safety framework for equipment used in potentially explosive atmospheres. Unlike standard units, an ATEX vacuum is specifically engineered to prevent the machine itself from becoming an ignition source.
A vacuum certified for ATEX Zone 22 (the most common industrial dust zone) is built with total anti-static continuity. Every component—from the hose to the motor—is designed to dissipate static electricity safely to the earth, ensuring that sparks cannot trigger a dust explosion.
Why Are ATEX Vacuums Important?
The importance of using ATEX-certified equipment goes beyond basic cleaning; it is a fundamental requirement for fire prevention and disaster mitigation:
- Explosion Prevention: Many common industrial dusts (like flour, sugar, or aluminium) become highly explosive when suspended in the air. ATEX vacuums eliminate the static discharge and motor sparks that cause "primary" explosions.
- Regulatory Compliance: In the UK, the DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) mandates that employers control the risks from fire and explosion. Using non-certified equipment in a designated ATEX zone is a major legal breach.
- Operational Continuity: A dust explosion can be catastrophic for a business. Investing in ATEX-rated machinery protects your facility, your infrastructure, and most importantly, your workforce.
Materials Suitable for ATEX Collection
ATEX vacuums are designed to safely handle combustible dusts and conductive materials that could otherwise cause a short circuit or ignition:
| Material Type | Common Sources |
| Combustible Food Dusts | Flour mills, sugar processing, grain silos, and spice blending. |
| Reactive Metal Powders | Aluminium, Magnesium, and Titanium dust from grinding or 3D Printing. |
| Chemical & Pharma | Processing of powders, organic pigments, and pharmaceutical ingredients. |
| Carbon & Coal Dust | Fuel handling, coal power facilities, and carbon fibre manufacturing. |
| Powder Coating | Over-spray from industrial painting and metal finishing lines. |
⚠️ Important Safety Note: ATEX Compliance
This guide is for informational purposes only and does not constitute a formal safety audit. Because explosive atmospheres vary by industry and material concentration, a comprehensive DSEAR Risk Assessment must be carried out by a qualified person to determine if your specific environment and the materials being collected require ATEX-certified equipment.
Failure to use correctly rated machinery in hazardous zones can lead to catastrophic ignition risks. For official UK regulatory guidance on ATEX and explosive atmospheres, please visit the HSE ATEX Equipment and Explosive Atmospheres page.
