ATEX & NFPA COMPLIANT INDUSTRIAL VACUUMS FOR COMBUSTIBLE DUST
Safeguard your facility with Depureco USA’s line of explosion-proof and intrinsically safe vacuum systems. Engineered for the recovery of combustible dusts, flammable fluids, and conductive metals in Class I and Class II environments.
Meet U.S. safety mandates. Our ATEX & NFPA Compliant (Class I Div 1 & Class II Div 1) explosion-proof vacuums are engineered to prevent ignition of flammable vapors and combustible dust, ensuring OSHA regulations and protecting your facility.
Operated by compressed air, not electricity, these vacuums eliminate all risk of spark or heat-based ignition. The ideal choice for the most sensitive hazardous locations where even certified electric motors are a concern.
Our inertization systems introduce an inert gas (like Nitrogen) into the vacuum stream to suppress combustion, providing an active layer of protection when vacuuming highly explosive dusts.
Customer safety is our utmost priority, and our solutions have been thoughtfully designed with this in mind. Our certified products undergo meticulous manufacturing processes that incorporate comprehensive precautions to ensure they do not pose a risk of ignition within hazardous areas, providing peace of mind and protection in such environments.
Combustible dust poses a significant safety risk in industrial settings, as it can lead to explosions and fires. Vacuum cleaners specifically designed for combustible dust removal offer specialized features such as explosion-proof construction, HEPA filtration, and static dissipation capabilities, ensuring safe and effective removal of combustible dust particles to mitigate the risk of ignition and maintain a safe working environment.
The hazard of combustible dust poses a significant risk in industrial settings, where fine particles can ignite and lead to explosions or fires. NFPA 660 standard serves as a crucial tool in mitigating this hazard by establishing comprehensive guidelines for the safe handling, storage, and ventilation of bulk solids, ensuring the protection of workers, facilities, and the surrounding environment
Explosion-Proof” typically refers to electrical equipment contained within a heavy-duty housing designed to withstand an internal explosion without igniting the surrounding atmosphere.
“Intrinsically Safe” often refers to pneumatic (air-powered) vacuums that use no electricity and have no moving mechanical parts, thereby eliminating heat and sparks at the source.
Depureco USA offers both ATEX-certified electrical units and intrinsically safe pneumatic systems for Class I and Class II environments.
Yes, in many specific applications.
ATEX is the rigorous European standard for explosive atmospheres. Equipment certified for ATEX Zone 22 is often engineered to meet or exceed the safety requirements for NFPA Class II, Division 2 environments.
Always verify with your local Authority Having Jurisdiction (AHJ), but Depureco’s ATEX-certified units provide a documented, third-party verified level of safety that standard “shop vacs” cannot match.
Pneumatic vacuums, like the Depureco Air-Powered Series, utilize a Venturi system to generate suction without electricity.
This makes them inherently safe for hazardous locations because they generate no heat and have no electrical motors that could spark.
They are the preferred choice for facilities with available compressed air lines looking for a maintenance-free, continuous-duty solution.
Unlike manual shaker systems that require the operator to stop work, Depureco’s JetClean® system uses a differential pressure sensor to trigger a powerful reverse jet of air automatically.
This cleans the filter during operation, maintaining peak suction and preventing dangerous dust accumulation on the filter media—a critical requirement for NFPA compliance.
Absolutely not.
Standard vacuums have internal motors where sparks can ignite conductive metal dust clouds, causing a violent explosion. You must use a specialized “Immersion Separator” or inertization vacuum.
Depureco’s inert systems immerse collected metal powder in a liquid bath (usually oil or water), instantly neutralizing the explosion risk by removing oxygen from the equation.
Yes.
All our explosion-proof and combustible dust vacuums come with a comprehensive technical dossier, including ATEX certificates, grounding continuity test results, and HEPA H14 filtration certificates.
This documentation is designed to support your Dust Hazard Analysis (DHA) and demonstrate due diligence to OSHA and fire marshals.
Using a standard shop vacuum for combustible dust is a severe safety violation and an explosion hazard. Standard commercial vacuums have three critical flaws that make them dangerous in hazardous environments:
