What Is Class II Division 2?
Class 2 Division 2 is a hazardous location classification defined by the National Electrical Code (NEC) and enforced by OSHA. It is one of the most common — and most frequently misunderstood — requirements in industrial dust management.
Class 2 Locations
A Class 2 location is any facility or zone where combustible dust can accumulate and become suspended in the air in sufficient concentration to create a fire or explosion hazard. Unlike vapor or gas hazards (Class 1), Class 2 deals specifically with solid particle dust — the kind generated in food processing mills, agricultural handling, plastics compounding, carbon processing, and dozens of other industries.
Division 2 Explained
Division 2 means the combustible dust hazard is NOT normally present under regular operating conditions. However, it can appear under abnormal circumstances — such as equipment malfunction, an accidental material release, maintenance activity, or a breach in a containment system. This distinction matters because Division 2 environments are common across U.S. manufacturing, yet many facilities unknowingly use non-rated vacuum equipment that creates the very ignition source regulations are designed to prevent.

Key Features & Benefits
Certified Safe for Hazardous Dust Environments
The ONE42.C2D2 carries full ETL Haz-Loc listing for Class II Division 2, Groups F and G — meaning it has been independently tested and verified to meet the electrical and mechanical requirements for operation in combustible dust locations. This is not a self-certification. It is third-party verification that the unit will not act as an ignition source in your facility.
Powerful 2 kW Suction — 340 m³/h Air Flow
Don’t mistake compact size for limited capability. The ONE42.C2D2 generates 210 mbar of depression and moves 340 cubic meters of air per hour — sufficient for demanding continuous-duty dust extraction tasks in production, maintenance, and cleanup applications. It’s built to handle the heavy loads that come with real industrial environments.
Quiet Operation — Designed for Active Work Environments
Excessive noise is a productivity and compliance issue. The ONE42.C2D2’s motor and airflow design prioritize acoustic control, allowing the unit to operate in active plant environments without creating additional noise exposure concerns for workers in proximity.
Large-Surface Star Filter with External Shaker
Clogged filters kill productivity and suction performance. The ONE42.C2D2 uses a high-surface-area star filter that maintains consistent suction across extended use cycles. The external filter shaker allows operators to clean the filter without opening the unit or making direct contact with captured dust — a critical safety feature when collecting hazardous combustible materials.
40-Liter Quick-Release Container
The 40-liter dust container is designed for rapid removal and replacement, minimizing operational downtime during dust disposal. Whether you need to swap a full container mid-shift or prepare for end-of-day cleanout, the ONE42.C2D2 is built for operational efficiency.
Compact Footprint — Fits Where Others Won’t
Floor space in industrial facilities is a premium. The ONE42.C2D2 is engineered with a compact, vertical footprint that fits into tight workspaces, along production lines, and in areas with limited overhead clearance — without sacrificing container capacity or suction power.
Two Configuration Options
Choose the version that fits your application and budget:
- X1 Version: Durable steel construction with RAL 9005 black trolley and RAL 7001 gray filter chamber — the standard workhorse for general industrial C2D2 applications.
- X2 Version: Fully stainless steel filter chamber and dust bin — ideal for food processing, pharmaceutical, and sanitation-sensitive environments where corrosion resistance and cleanability are required.

FAQ
-
Q: What does Class II Division 2 mean, and why does it matter for my vacuum?
Class II Division 2 is a hazardous location classification established by the National Electrical Code (NEC) for environments where combustible dust can be present under abnormal or fault conditions. Equipment rated for Class II Division 2 must be constructed to prevent internal sparking, arcing, or heat generation that could ignite suspended dust. If your facility processes grain, flour, starch, sugar, plastics, carbon, or similar materials and uses a non-rated vacuum, you may be in violation of OSHA regulations and creating a fire or explosion risk. The ONE42.C2D2 is ETL Haz-Loc listed for Class II Division 2, meaning it has been tested by an independent laboratory and confirmed to meet these safety requirements.
-
Q: What is the difference between Group F and Group G dust?
Group F covers carbonaceous dusts — coal, coke, carbon black, graphite, charcoal, soot, and ash — typically generated in mining, foundry, and carbon processing operations. Group G covers organic combustible dusts — grain, flour, starch, sugar, cocoa, wood dust, plastics, and other similar materials — common in food processing, agriculture, pharmaceuticals, and woodworking. The ONE42.C2D2 is rated and certified for both groups, making it a versatile solution for multi-dust environments or facilities that want a single certified vacuum platform.
