FAQ

The two tools have different purposes based on different physical principles:

• Vacuum: works with high vacuum pressure (suction force) and lower airflow. It is designed to lift and transport materials (solids, liquids, dust) from a surface through a hose. It is primarily a cleaning and collection tool.

• Dust collector: works with high airflow and lower vacuum pressure. Its purpose is to capture large volumes of fine and light dust suspended in the air, typically extracting directly from a machine (e.g., a sander) to purify the workplace air.

It refers to the type of motor (or blower) used. Side channel blowers are designed to generate high vacuum pressure (suction force), making them ideal for vacuuming heavy materials or for use in centralized systems with long piping.

It is a type of vacuum specifically designed for the woodworking or metalworking sector. It uses a high airflow to capture larger chips and sawdust, conveying them into large collection bags.

The industrial vacuum is for heavy-duty use and various materials (solids, liquids, fine dust). The household vacuum cleaner is for domestic use and common dust. The ash vacuum is specifically designed to vacuum cold ashes from stoves and fireplaces, equipped with special filters and protections for this type of fine, abrasive dust.

It is a suction technique that captures dust or fumes directly at the point where they are generated by a machine, preventing their dispersion into the environment and ensuring maximum effectiveness.

The difference is substantial and concerns material robustness: (steel vs. plastic), motor power and quality, continuous duty capability: (24/7 for three-phase models), filter surface and type: (able to handle significant airflow), collection capacity, and compliance with specific safety regulations: (e.g., ATEX).

Although the terms are sometimes used interchangeably, there is a technical distinction.

• Professional vacuum: a robust machine, often single-phase, designed for intensive but not continuous use. It is the ideal solution for cleaning companies, workshops, car washes, and craftsmen.
• Industrial vacuum: built for the needs of industrial production. It is often equipped with a three-phase motor for continuous operation (24/7), has an all-steel construction, advanced filtration systems for specific dusts (toxic, explosive), and is designed to be directly integrated into production cycles.

To evaluate the suction power of an industrial vacuum cleaner, several key parameters must be considered, which together provide a complete picture of its performance:

• Vacuum (or Static Pressure): Measured in mbar or kPa, it indicates the vacuum’s ability to create negative pressure and lift heavy materials or overcome resistance (e.g., long hoses, dirty filters). A high value is essential for suction of chips, dense liquids, gravel, or applications that require strong “pulling power.”
• Airflow (or Flow Rate): Measured in m³/h or L/s, it indicates the volume of air moved. High airflow is crucial for quickly removing large amounts of fine or light dust, fumes, or for efficiently covering wide surfaces.
• Motor Power (kW or HP): Although not the only factor, higher motor power generally allows for higher vacuum and airflow performance.
• Filtration System Efficiency: A good filter maintains suction performance over time and ensures clean exhaust air.
• Application Type: The ideal “power” depends on the material being vacuumed (liquids, solids, fine dust, heavy debris) and the system complexity (hose length, number of suction points).

An industrial cyclone vacuum uses the principle of centrifugal force to separate larger dust and debris particles from the air before they reach the main filter. The dust-laden air enters tangentially into a conical chamber (cyclone), creating a vortex. Heavier particles, due to inertia, are pushed against the walls and fall into a collection container below, while the cleaner air continues toward the filter. This system extends filter life, reduces cleaning or replacement frequency, and maintains more consistent suction power, making it especially useful for collecting large volumes of material or abrasive dust.

The average lifespan of an industrial vacuum is significantly higher than that of a household vacuum, due to its robust construction and intended use. A high-quality industrial vacuum, properly maintained and used for the application it was designed for, can last between 10 and 20 years, or even longer. Factors such as the quality of components (motors, filters, frame), usage frequency, and the type of material vacuumed greatly influence its longevity.

In a corporate context, the need for a specific vacuum cleaner is determined by the Health and Safety Manager, the safety consultant, or the production manager, based on the risk assessment and process requirements.

The “best” vacuum is the one that perfectly meets the specific needs of a company. There is no universally superior model, only the solution best suited for a given job.

Absolute “power” does not define the “best” vacuum. The most powerful model for a given application is the one that offers the right balance between vacuum pressure and airflow for the specific material to be collected, ensuring efficiency and safety.

Power (expressed in Watts or kW) is important, but it is not the only parameter. It is especially necessary to evaluate vacuum pressure (mbar or mmH₂O): which indicates the suction force, and airflow (m³/h): which indicates the volume of air moved. Heavy materials require high vacuum pressure; light and bulky materials require high airflow.

The choice depends on 5 main factors:

• Material: type (dust, liquid, solid), particle size, and nature (e.g., explosive, toxic).
• Quantity: how much material needs to be vacuumed per day.
• Application: continuous or intermittent use, machine-side suction or general cleaning
• Environment: presence of explosion-risk zones (ATEX) or confined spaces.
• Operator: need for ergonomics, ease of emptying, and mobility.

Finding the “quietest” industrial vacuum is a challenge, as the power and airflow required for industrial use often produce a certain level of noise. However, manufacturers are investing in noise reduction technologies such as motor insulation and low-noise fans. To identify a relatively quiet industrial vacuum, look for a specified noise level in decibels (dB) — ideally below 70–75 dB, which is considered good for this category.

There is no single “best” brand, as each manufacturer has specific strengths, and the best solution depends on the unique industrial needs of the user. The main competitors and reference brands in the industrial vacuum market—known for their engineering, reliability, and range of solutions—include:

• Depureco: Italian manufacturer specialized in high-power vacuums, with solutions for every industrial need.
• Nilfisk: Offers a wide range of industrial vacuums for various applications.
• Karcher: Known for the versatility of its products, both for professional and industrial use.
• Ruwac: Renowned for high-quality plastic vacuums, including ATEX models and those for difficult materials.
• Delfin: Specialized in vacuums for specific sectors.

Determining the “best” industrial cyclone vacuum depends on several factors specific to the application (type of material, volume, ATEX environment, etc.). However, among the leading and most respected brands known for their industrial cyclone vacuum solutions—recognized for reliability, durability, and performance—are: Depureco, Nilfisk, Ruwac, Delfin, Starmix, Karcher, and Dustcontrol. Many of these manufacturers offer modular cyclone systems or integrate cyclone separation in their advanced units.

For an industrial vacuum, power in Watts (W) is an important indicator, but not the only one. The required power depends on the specific application: fine dust, chips, liquids, heavy material, continuous operation. Typically, industrial vacuums start at 1000–1500W for light and intermittent use, reaching 3000W, 5000W, or even over 10,000W for heavy-duty and continuous cycle applications. It’s essential to also evaluate the actual suction power (measured in mbar or kPa) and airflow rate (measured in m³/h), along with the quality of the filtration system.

It’s essential to maintain the vacuum’s performance. A clogged filter drastically reduces suction power. Filter cleaning systems can be manual (usually a filter shaker) or automatic (typically with compressed air pulses), helping keep the filter free from dust.

ACD (Appliance for Combustible Dust) vacuums are defined by IEC 60335-2-69:2021 and are designed for the safe extraction of combustible dust. They feature antistatic filtration and complete grounding but are not certified for use inside ATEX zones, and should only be used in non-classified areas.

These are vacuums built according to European ATEX directives, especially the new EN 17348:2022, which sets strict safety requirements for vacuums operating in explosion-risk environments. They are designed for safe use in classified areas (e.g., Zones 21 and 22 for dust) and include certified motors, antistatic filters, full grounding, and spark-proof components.

These are dusts that, when dispersed in the air at a certain concentration and exposed to an ignition source, can cause explosions. Their explosive potential is measured by the Kst value, which indicates the maximum rate of pressure rise during an explosion.

Kst Classes:

• Kst 0 – Non-explosive
• Kst 1 (1–200 bar·m/s) – Low explosiveness
• Kst 2 (200–300 bar·m/s) – Moderate explosiveness
• Kst 3 (>300 bar·m/s) – High explosiveness

Even low-Kst dusts can be dangerous if not properly handled.

They are dust particles with a diameter smaller than 10 and 2.5 micrometers respectively. They are particularly dangerous because they can be inhaled and reach deep into the respiratory system, causing health problems.

According to IEC 60335-2-69, dusts are classified into three risk classes based on their danger level:

• Class L (Low risk): Low-risk dusts (e.g. household dust, soil). Filtration efficiency > 99%.
• Class M (Medium risk): Medium-risk dusts (e.g. wood, cement, paint dust). Filtration efficiency > 99.9%.
• Class H (High risk): High-risk, carcinogenic or pathogen-contaminated dusts (e.g. asbestos, silica, lead, mold). Filtration efficiency > 99.995% (using HEPA filters).

In industrial vacuum systems, “suction power in Pa” (Pascal), or more commonly in mbar (millibar) or kPa (kilopascal), refers to the vacuum pressure or negative pressure the vacuum can generate. This parameter indicates the unit’s ability to lift and move materials—even heavy ones—through the piping system. A higher value in Pa/mbar/kPa means stronger suction and better capability to handle heavy loads or longer distances.

Prolonged exposure can lead to various respiratory conditions such as asthma, chronic bronchitis, and silicosis (from silica dust), up to much more serious diseases.

ATEX and ACD vacuums are structurally similar but differ in use, certifications, and motor type.

• Use case: Both can vacuum combustible dust, but only ATEX vacuums can operate inside ATEX-classified zones.
• Certifications: ACD vacuums follow strict construction criteria but require no formal certification. ATEX vacuums must be certified to prove compliance with applicable safety standards.
• Motors: Vacuums used in ATEX zones must use motors that are spark-free and safe from ignition risks.

Yes, these are called “Wet & Dry” vacuums. The most advanced models, known as sump vacuums or chip and oil vacs, can vacuum large quantities of liquids (e.g., coolant oil), separate the solid part (chips), and return the clean liquid to the machine—resulting in significant savings.

It’s ideal for quick maintenance tasks, cleaning in tight or hard-to-reach spaces, and for tool-connected vacuuming (e.g., sanders, drills).

• Single-phase: Uses brush motors, ideal for intermittent use and general cleaning applications. They are lighter and easier to handle.

• Three-phase: Equipped with side channel blowers, designed for continuous operation (even 24/7), for machine-side suction or centralized systems.

The airflow rate (or air volume) of an industrial vacuum cleaner is a technical specification provided by the manufacturer and not something the user typically calculates directly. It is measured in cubic meters per hour (m³/h) or liters per second (L/s). This parameter indicates the volume of air the vacuum can move in a given time. High airflow is crucial for quickly removing large volumes of light materials, fine dust, or for centralized vacuum systems covering wide areas.

The benefits include the ability to vacuum from multiple points simultaneously, reduced noise in production areas (the motor is remote), centralized material collection and disposal, and a very high level of cleanliness and efficiency.

Filters can be cleaned using different systems:

• Manual, with a lever shaker
• Semi-automatic, with air pulses activated by a button
• Automatic, with programmed cycles such as Jet Clean, SP, or PSC

The choice depends on the type of dust and the required continuity of use.

A well-designed and properly maintained centralized system can last over 15–20 years. Longevity depends on the quality of components, maintenance frequency, and proper sizing according to production needs.

Yes, modern systems can integrate with automation, remote control, and Industry 4.0 integration. Parameters such as airflow, vacuum level, and filter status can be monitored, with preventive maintenance alerts, optimizing management of the entire production system.

The space required varies depending on the size of the system and the number of suction points. Normally, the main units are installed in a technical room or outside, reducing internal footprint. The piping is designed to integrate seamlessly with the existing infrastructure.

The air velocity must be sufficient to transport the material without settling in the pipes. Typically, values between 20 and 30 m/s are calculated, depending on the particle size and density of the dust or chips, to ensure a constant flow and prevent clogging.

Power is calculated by considering several parameters: required airflow, vacuum level, number of operators working simultaneously, pipe length, and the type of material to be collected. Proper sizing ensures consistent performance without energy waste.

Operator safety is ensured through proper system design, the use of suitable filters, explosion protection devices, and staff training. In addition, suction units are often installed in separate technical rooms, reducing noise, direct exposure, and risks related to the collected materials.

In addition to the ATEX directive, centralized systems must comply with European workplace safety regulations, filtration standards (such as EN 1822 for HEPA filters), and local health and environmental requirements. Compliance ensures the system is safe, efficient, and legally compliant.

Centralized systems can include several safety systems:

• Explosion panels or relief valves to reduce pressure in case of explosion
• Liquid inertization systems to neutralize reactive dust
• Automatic extinguishing systems with CO₂ or chemical powder
• Grounding and antistatic components

These measures ensure maximum safety even in high-risk environments.

An ATEX system is mandatory in all environments classified as explosion-risk areas, such as ATEX Zones (Z20, Z21, Z22). The requirement depends on the type and frequency of explosive dust or gas presence. In these cases, the law requires certified solutions to protect both workers and production facilities.

ATEX certification is a European directive that establishes safety requirements for equipment and systems intended to operate in potentially explosive atmospheres. It ensures that every component is designed to prevent ignition and minimize risks, making the system suitable for environments with combustible dust, vapors, or flammable gases.

Centralized systems are used in many sectors, the most common being:

• Metalworking, for collecting chips and metal dust.
• Wood, for collecting sawdust and flammable chips.
• Food, to ensure the cleaning of flour, sugar, and organic dust.
• Pharmaceutical and chemical, where vacuuming toxic or combustible dust is essential.
• Construction and manufacturing, for fine dust and processing residues.

This versatility makes centralized systems a universal solution adaptable to many different contexts.

Yes, but in this case, ATEX-certified systems and additional safety devices such as explosion relief valves, inerting systems, or automatic extinguishing are essential. Combustible dust, if not properly managed, represents a high explosion risk. A certified centralized system allows operations to be carried out in complete safety.

Certainly, provided they are designed with high-efficiency absolute filters, such as HEPA H14 filters. These ensure the capture of particles down to 0.3 microns and prevent harmful dust from being released back into the air. The system must also be airtight and comply with safety regulations to protect workers and the work environment.

A centralized vacuum system can handle virtually any material: fine dust, metal chips, sawdust, processing residues, fumes, and even liquids. The important thing is to design the system according to the specific material, selecting the appropriate filters, piping, and accessories. This ensures safety, production continuity, and long-term efficiency.

The most common mistakes are: underestimating pipe pressure losses, choosing inadequate diameters, neglecting simultaneous use, or failing to consider the specific nature of the dust. Incorrect placement of filter units can also reduce performance and safety. This is why it is essential to rely on experienced designers who assess every technical detail.

The suction unit is usually installed in a dedicated technical room or outside the production area. This reduces noise levels in production, improves safety, frees up workspace, and simplifies maintenance. Placing it strategically also helps reduce pipe length and maximize energy efficiency.

It has a decisive impact. Light materials such as fine dust require high airflow, while chips or heavy solids require stronger vacuum. For hazardous or combustible dust, certified ATEX systems, specific filters, and additional safety systems are required. Each material therefore leads to different choices of motor, filters, and accessories.

Airflow is calculated by considering the minimum speed required to safely transport dust and solids inside the piping. In general, diameter, path length, and materials to be collected are evaluated. Proper airflow ensures continuous flow, prevents blockages or deposits, and reduces the risk of system downtime.

 Power depends on several combined factors, such as:

• distance to the farthest suction point,
• amount of material to be collected,
• number of inlets used simultaneously,
• required filtration level.

Accurate calculation prevents under-sizing (causing inefficiency) or over-sizing (leading to higher energy costs).

Yes, the architecture is modular and scalable. It is possible to add suction inlets, extend lines, or upgrade the motor and filters in case of increased requirements. Each expansion must, however, be checked against airflow, available vacuum, and filtration system, and may require replacement of suction and filtration units.

The piping can extend for tens of meters and cover multiple floors, provided that pressure losses, diameters, and layout are correctly calculated. Using larger mains and linear paths helps maintain constant airflow and vacuum throughout the network.

It depends on the project: the system is designed based on simultaneous use, for example 3/4 operators active at the same time. During the design phase, the required number of concurrent points must be specified (maximum 3/4); if not specified, only one will be used at a time.

A mobile vacuum is standalone, easy to move, and suitable for occasional or localized tasks. A centralized system, on the other hand, serves multiple workstations simultaneously thanks to a powerful motor group and a fixed piping network. It is the ideal solution for large surfaces, complex departments, or multi-level facilities.

Compared to mobile solutions, a centralized system ensures continuous multi-point suction, reduces noise on the shop floor thanks to the remote motor, and centralizes material collection, avoiding movement and clutter inside departments. In addition, it requires less maintenance, speeds up cleaning operations, and improves ergonomics, safety, and operator productivity.

An industrial centralized vacuum system is a fixed installation designed to collect dust, solids, and sometimes liquids from large areas or production departments. It consists of a suction unit, a filtration and collection system, and a network of pipes connected to distributed inlets. It channels everything into a single point, keeping workplaces clean and the air filtered.

Delivery times for industrial vacuum cleaners can vary significantly compared to consumer products, due to their often more complex nature, customization options, and logistics. Generally, production begins at the time of order, but in general:

• Standard Available Models: For in-stock, series-production industrial vacuums, delivery times can range from 3 to 7 business days.
• Made-to-Order or Customized Models: For more complex systems, vacuums with special specifications (e.g., ATEX certifications, special motors), or custom-built solutions, delivery times can extend from 2 to 8 weeks or more, depending on production and assembly times.
• Components and Spare Parts: Availability and delivery times for filters, bags, and other essential spare parts may range from a few days to a few weeks.

It’s always crucial to ask for a delivery time estimate at the quotation or ordering stage, as fluctuations may occur based on demand, component availability, and the supplier’s production capacity.

The warranty for industrial vacuum cleaners is generally governed by the Civil Code and the conditions of the manufacturer/seller. In Italy, the minimum legal warranty for goods purchased by professionals (B2B) is typically 1 year from the date of purchase, covering hidden defects or non-conformities.

It is common for industrial vacuum manufacturers to offer extended or conditional warranty terms. For example, Depureco offers a 2-year extension beyond the standard warranty if the buyer purchases a set of original replacement filters.

The cost of installing an industrial vacuum can vary greatly depending on the system’s complexity and the vacuum type:

• Stand-alone Mobile Vacuums: Generally involve minimal installation costs, as they are “plug and play” units requiring only proper electrical connection.
• Centralized Vacuum Systems: These require professional design and installation, including the pipe network, inlets, central vacuum unit, filtration system, and waste disposal. Costs can range from a few thousand to hundreds of thousands of euros, depending on the system’s size, number of suction points, ducting complexity, and any required certifications (e.g. ATEX).
• Machine-Integrated Vacuums: Installation costs are often included in the machine’s overall price or may require specialist integration services.

Buying is a long-term investment, ideal for continuous use. Renting can be a cost-effective solution for temporary needs, seasonal work peaks, or to test a model before purchasing.

The key factors influencing the final cost are: the motor’s power and type, the size of the filter and the unit, the presence of certifications, construction materials (e.g., stainless steel), any factory-installed optional features (such as automatic shut-off systems, electrical panels, inverters), and dedicated accessories for the intended application.

The price of an industrial vacuum varies greatly. It is not possible to define a standard cost, as it depends on dozens of factors, especially related to the machine’s intended application. As a purely indicative range, here is a general breakdown:

• Professional/Single-phase Models: Can start at around €200 – €300 for basic versions and reach up to €2,000 for more powerful, accessorized models. Ideal for cleaning companies, Ho.Re.Ca., and non-industrial applications.
• Industrial/Single-phase Models: Prices typically range from around €800 – €1,000 for entry-level models, and up to €3,000 – €4,000 for higher power, fully equipped units.
• Industrial/Three-phase Models: Higher price range. Starting from about €3,000 for compact units, and can exceed €20,000 for high-power models with specialized filters and certifications (e.g. ATEX).
• Specialized Solutions (e.g. Oil vacuums, toxic dust): The price depends on design and construction features and may be significantly higher than standard products.

The cost can vary greatly depending on the power of the vacuum unit, the complexity and length of the piping network, the number of suction points, and the required accessories. Prices can range from a few thousand euros for simple systems to tens of thousands for complex installations.
