The Basics: What It Is, How It Works, and Why You Should Use an Industrial Vacuum
An industrial vacuum is a powerful device designed to remove dust, solid debris, and liquids from industrial environments. Unlike traditional vacuum cleaners, these machines offer higher performance, durability, and safety features suited for demanding production settings.
What Is an Industrial Vacuum?
An industrial vacuum is a professional-grade cleaning system that uses powerful motors, specialized filters, and heavy-duty components. These machines are designed to remove fine dust, industrial waste, hazardous materials, and liquids, ensuring safe working conditions and compliance with environmental regulations.
Every industrial vacuum is built around three essential parts:
- Vacuum unit: this is the component that generates the vacuum, enabling suction. It is typically powered by an electric motor, although other types also exist.
- Advanced filtration system: this is the part that separates the air from the collected material. The system consists of a filter (either single-stage or multi-stage with progressive efficiency) and an integrated filter cleaning mechanism.
- Material collection system: this component handles the collection, management, and eventual disposal of the vacuumed dust or debris. It typically consists of a steel container, although various systems are available to meet specific needs.

How does an Industrial Vacuum work?
- Vacuum generation: The motor creates negative pressure (vacuum) inside the unit, generating a powerful airflow. This airflow is responsible for the suction effect that draws in dust, debris, and liquids.
- Material collection: The moving air captures and lifts residues from surfaces or directly from industrial equipment. These materials are then vacuumed and transported into the vacuum through a flexible hose.
- Separation and filtration: Once vacuumed, the materials are separated from the air using filters specific to the type of material being removed. This process ensures that solid particles or liquids do not return into the environment along with the clean air.
- Residue collection and air discharge: The separated residues are deposited into an internal container within the vacuum for later disposal. The filtered air is then released back into the environment, free of impurities or contaminants, ensuring safety and cleanliness in industrial settings.

Selection Guide: How to choose the ideal vacuum model for your needs in 5 steps
The correct selection of an industrial vacuum directly affects operator safety, environmental health, and production continuity. An incorrectly sized system can generate health risks, regulatory violations, and unexpected operating costs.
1. Analyze the nature of the materials to be removed
First, identify the type of substances to be vacuumed:
- Fine Dust (e.g. flour, toner, cement)
- Swarf and solid waste (e.g. metal, wood, plastic)
- Liquids or sludge (e.g. oils, emulsions, metal sludge)
- Fumes and vapors (e.g. welding, solvents)
Each material requires a different configuration to ensure effective collection and durability of the filter system.
Classification of dusts according to IEC 60335-2-69:
The classification of dusts according to IEC 60335-2-69, which concerns industrial vacuum, divides dusts into three main categories based on their dangerousness: L, M, and H. These categories determine the level of filtration necessary to protect operators and the environment.
- Class L (Low): Low-risk dusts, such as those derived from soft wood and gypsum, with an exposure limit value (ELV) greater than 1 mg/m³. They do not require special precautions for disposal.
- Class M (Medium): Dust with a ELV between 0.1 and 1 mg/m³, such as that derived from wood, concrete, cement, and similar materials.
- Class H (High): Carcinogenic, mutagenic, or pathogenic dusts with a VLEP below 0.1 mg/m³, such as asbestos, mold, and bacteria. These require a high level of filtration and specific precautions for handling and disposal.
The standard also specifies that, based on the ‘level of dangerousness,’ filters must have a maximum penetration rate of <1% for class L, <0.1% for class M, and <0.005% for class H, respectively.
In addition, flammable dusts are classified according to their explosive potential into categories from St0 to St3, where St0 indicates zero risk of explosion and St3 indicates a very high risk.
In summary, the IEC 60335-2-69 classification is essential for ensuring operator safety and preventing health and safety risks associated with the presence of dust in the workplace.
2. Adjust the suction power according to the load
Consider two key technical parameters:
- Air flow rate (m³/h): measures the volume of air displaced. It must be increased as the amount of material to be removed increases.
- Depression (mmH₂O o kPa): represents the force with which the system lifts the material. It must be increased as the weight of the material to be removed increases.
For heavy debris or long-distance transport, high values are required for both parameters, which only high-powered industrial vacuum can guarantee.
3. Choose the most suitable filter system
Filtration is at the heart of how a vacuum works. Choosing the right filter depends greatly on the type of material to be vacuumed:
- Filtration efficiency: Indicates the filter’s ability to retain particles of a specific size. The higher the efficiency, the greater the protection for the operator and the environment.
- Filtering surface: This is the actual area available for retaining dust. A large surface area extends the vacuum’s autonomy and reduces the frequency of maintenance.
- Filter media: This refers to the material used to construct the filter (e.g., polyester, fiberglass, cellulose). Each medium has specific characteristics in terms of resistance, washability, and compatibility with dangerous substances.
The combination of these three elements will allow you to choose the right filter, which must include an effective cleaning system. With the right cleaning system, it will be easier to maintain the system’s maximum suction performance at all times.
4. Assess how the vacuumed material should be handled
Assessing the desired management of the material to be vacuumed in advance is essential to ensure operational continuity and reduce downtime. Here’s what to consider:
- Container of adequate capacity: choosing a container proportionate to the amount of material collected avoids too frequent emptying and interruptions to the work cycle. Choose a stainless steel tank for corrosive or specific applications.
- High-volume management: for intensive applications, advanced solutions are available, such as:
- Direct filling: ideal for hazardous materials or fine dust, it reduces contact with the operator.
- Big-Bag discharge: simplifies the handling of large quantities, minimizing dust dispersion.
These solutions optimize emptying operations, improving efficiency and safety.
5. Select accessories suitable for use.
The choice of accessories is crucial for adapting the vacuum to actual operating conditions. Reinforced polyurethane hoses guarantee resistance to abrasive substances and high temperatures. Floor nozzles, telescopic wands, and antistatic brushes allow for targeted cleaning on different surfaces. Articulated suction arms and accessory trolleys improve maneuverability and operating comfort. Using specific accessories improves suction efficiency, reduces system wear, and increases overall productivity.

Handling Dangerous Dust
Use ATEX-certified vacuum for combustible dusts. Always comply with the manufacturer’s specifications regarding the characteristics of the dusts that can be vacuumed, including the minimum ignition energy (MIE).
Prevention of Electrical and Mechanical Risks
Keep electrical cables intact and always use an effective grounding system. Do not expose the device to high humidity or extreme environmental conditions.
Emergency Procedures
In the event of a malfunction, immediately turn off the power supply and follow the procedure indicated in the instruction manual and the company’s accident management procedure.
General Overview of Regulations
Industrial vacuum must comply with stringent national and international regulations. European directives include the Machinery Directive 2006/42/EC, EMC 2014/30/EU, RoHS 2011/65/EU, and IEC 60335-2-69 standards. For environments at risk of explosion, it is essential to be familiar with the specific ATEX, NFPA, and IECEX directives.
ATEX Regulations
The ATEX (Atmosphères Explosibles) regulation is crucial for companies operating in environments with combustible gases, vapors, mists, or dusts.
According to the regulations, each establishment must:
- Identify and classify areas at risk of explosion (Zones 0, 1, 2 for gases and vapors; Zones 20, 21, 22 for dust).
- Ensure that equipment used in classified areas is ATEX certified and suitable for the type and level of risk identified.
- Adopt written and specific procedures for the maintenance and cleaning of environments to prevent the formation and accumulation of explosive atmospheres.
ATEX directive (2014/34/UE)
This directive regulates equipment for potentially explosive environments. It certifies that the equipment is designed to prevent the ignition of explosions from energy sources (e.g., electrical or mechanical sparks).
Norm EN 17348:2022
The EN 17348:2022 standard, effective from March 2023, is essential for industrial vacuum that collect combustible dust. It specifies minimum construction requirements and protection systems, with a focus on preventing explosions inside the vacuum cleaner. A critical aspect is ATEX certification for the “internal zone 20” of the vacuum. This means that the vacuum is safe even when handling high and persistent concentrations of combustible dust inside it.
This certification guarantees that, even with continuous suction of highly flammable dust, the internal components do not become a source of ignition.
NFPA Regulations 660
In the United States, safety relating to combustible dusts is primarily regulated by the standards of the National Fire Protection Association (NFPA). An important new development is the introduction of NFPA 660: Standard for Combustible Dusts and Particulate Solids, which consolidates and replaces several previous standards (including NFPA 652, NFPA 654, NFPA 484, NFPA 61, NFPA 655, and NFPA 664). This unification aims to simplify and clarify safety requirements.
NFPA 660 provides a unified framework for identifying, evaluating, and controlling fire, flash fire, and explosion hazards associated with combustible dusts and particulate solids. Its main objectives are:
- Minimize fires and explosions.
- Maintain business continuity.
- Protecting the health and safety of workers.
NFPA 660 imposes specific requirements on facilities that handle combustible dusts:
- Dust Hazard Analysis (DHA): Each facility must conduct a dust risk analysis to identify and assess hazards. This analysis must be reviewed and updated at least every 5 years or in the event of significant changes to the process.
- Identification of Dust Properties: Determine whether dusts are combustible or explosive through specific tests (e.g., Kst, Pmax, MEC, MIE, MIT).
- Engineering Controls: Implement control systems such as dust collection and ventilation to minimize dust accumulation and dispersion.
- Administrative Controls: Adopt regular cleaning (“housekeeping”) procedures to prevent dust accumulation (often with specific accumulation thresholds).
- Control of Ignition Sources: Manage and prevent ignition sources such as sparks, hot surfaces, static electricity (through grounding and bonding), and foreign objects.
- Equipment Design: Equipment should be designed to prevent dust leakage and control ignition sources.
- Training and Maintenance: Comprehensive training programs for personnel and preventive maintenance plans for equipment.
Although OSHA (Occupational Safety and Health Administration) does not have specific formal regulations for combustible dusts such as the European ATEX Directive, OSHA frequently relies on NFPA standards, often citing the “General Duty Clause” to require employers to maintain a workplace that is safe from recognized hazards. Therefore, compliance with NFPA 660 is vital for accident prevention and to avoid penalties in the United States.
IECEx Regulations
The IECEx (International Electrotechnical Commission Explosive Atmospheres) standard is an international standard that regulates the use of electrical and mechanical equipment in explosive atmospheres, ensuring uniformity in technical requirements and compliance testing worldwide.
According to IECEx, each facility must ensure that:
- Equipment used in potentially explosive areas must be IECEx certified and comply with international safety requirements.
- Operating, maintenance, and cleaning procedures are clearly documented to ensure safety and ongoing compliance with IECEx requirements.
- Personnel must be adequately trained and kept up to date on the safety measures necessary for working in explosive atmospheres.
In this case too, IECEx-certified industrial vacuum are considered the optimal solution for the safe management of combustible dusts and explosive materials, thanks to their ability to eliminate ignition risks and effectively contain any associated hazards.
