HZD900 Core Features & Unrivalled H-Class Filtration
The Numatic HZD900 is built with a sophisticated, triple-stage sealed filtration system, providing the high-capacity suction required for industrial-scale hazardous dust extraction.
H-Class Certified Filtration (99.995% Efficiency)
- HEPA H13 Filter Module: The heart of this industrial machine is a massive, high-efficiency HEPA H13 cartridge filter securely housed in an all-steel module. This system ensures 99.995% filtration efficiency down to 0.3 microns.
- Triple-Stage Containment: Filtration consists of: 1) HepaFlo Dust Bag NVM-4BH (Primary high-capacity containment); 2) Large Surface TriTex Filter (Protects the main HEPA module); and 3) HEPA H13 Filter (Final absolute filtration).
Heavy-Duty Industrial Construction
- Twin 960W TwinFlo Motors: Unlike smaller models, the HZD900 features two professional-grade motors providing a combined 1920W of power. This delivers the exceptional airflow (80 L/sec) needed for heavy-duty extraction and long hose lengths.
- 40L Structofoam Drum: The massive 40-litre capacity is housed in a "built-to-last" Structofoam body. This material offers the strength of steel without the weight, and it is entirely resistant to dents, scratches, and corrosion.
- Steel Chassis & Transit Trolley: Mounted on a rugged, heavy-duty steel chassis with large rear wheels and industrial front castors, ensuring the HZD900 remains highly manoeuvrable even when full.
- 10m NuCable System: Includes a plugged, replaceable power cable that can be swapped instantly on-site without the need for a qualified electrician, minimising downtime.
3. Safety & Compliance Features
- Safe Emptying: Designed for use with large-capacity, triple-layer HepaFlo Filter Bags (NVM-4BH) which feature a secure sealing tab, guaranteeing dust-free disposal of hazardous waste.
- Total Containment: Equipped with screw-on dust caps for the drum and the power head, effectively sealing the unit during transport to prevent any hazardous particles from escaping.
- Airflow Indicator: Features a visual pressure sensor that monitors filtration performance, alerting the operator immediately if a blockage occurs or the bag is full
- Certified Documentation: Every HZD900 is supplied with individual H-Class HEPA certification, providing essential proof of compliance for health and safety audits.
🏭 Where the Numatic HZD900 Can Be Used (Applications)
The HZD900’s Twin-Motor power and 40L capacity make it the primary choice for large-scale industrial projects where high-volume hazardous dust is generated.
- Asbestos Abatement: Large-scale stripping and remediation projects requiring continuous high-volume extraction.
- Manufacturing & Chemical: Handling finely divided metallic dusts, chemical processing powders, or pharmaceutical by-products.
- Industrial Woodworking: Centralised extraction for machines producing high volumes of MDF or hardwood dust.
- Construction & Grinding: Localised extraction for floor grinders, wall chasers, and large-scale masonry cutting (Silica control).
- Specialist Restoration: Large-scale mould remediation and lead paint removal in industrial or heritage buildings.
- Chimney & Flue Maintenance: Professional chimney sweeping and flue cleaning, providing high-suction containment of hazardous soot, creosote, and ash.
☣️ What Material the HZD900 is Certified to Collect
The HZD900 is certified to capture dusts with a Workplace Exposure Limit (WEL) of <0.1 mg/m³, meeting the legal criteria for H-Class (High-Hazard) classification.
1. High-Hazard (H-Class) Materials
- Asbestos: High-volume fibre collection during professional abatement and stripping.
- Lead Dust: Safe containment of lead-based paint debris from large-scale sanding.
- Carcinogenic & Toxic Dusts: Including Cadmium, Beryllium, Nickel, and Formaldehyde.
- Pathogenic Dusts: Bacteria, viruses, and biohazards waste in clinical or lab settings.
2. Medium-Hazard (M-Class) Materials
While rated for H-Class, the HZD900 is the superior choice for high-volume M-Class dusts to ensure maximum protection:
- Respirable Crystalline Silica (RCS): From concrete, brick, stone, and mortar.
- Hardwood Dust: From Oak, Beech, and MDF manufacturing.
What Accessories Are Included with the HZD900?
-
BB20 Industrial Kit: This machine comes with a comprehensive 38mm industrial accessory set, including a 3.0m Nuflex threaded hose, stainless steel tubes, a 400mm heavy-duty floor tool, and specialist dusting/crevice nozzles.
💡 Why Purchase the HZD900 (The H-Class Twin-Motor Difference)
The HZD900 is a critical investment in legal compliance, productivity, and risk mitigation.
- Legal Compliance (COSHH): Fully meets the legal requirements for handling high-risk dusts under COSHH regulations.
- Maximum Productivity: The twin-motor setup and 40L drum allow for faster cleaning and fewer bag changes, keeping your team on task for longer.
- Absolute Containment: The sealed H-Class system guarantees that 99.995% of hazardous particles are trapped, preventing them from being exhausted back into the workspace.
Understanding H-Class Vacuum Cleaners: Safety & Compliance Explained
In industrial and specialist environments where dust is not just a nuisance but a life-threatening hazard—such as asbestos removal, lead abatement, or pharmaceutical manufacturing—even M-Class equipment is not enough. For the most dangerous airborne particles, H-Class vacuum cleaners are the only legally compliant and safe solution.
What is an H-Class Vacuum Cleaner?
H-Class (High-Hazard Class) is the highest international safety standard for professional dust extraction. While M-Class vacuums are designed for medium-risk dusts, H-Class machines are engineered to contain highly carcinogenic, pathogenic, and toxic materials.
A vacuum certified to H-Class standards is guaranteed to capture at least 99.995% of the dust it processes. These machines utilize HEPA H14 filtration (the highest grade) and are built with fully sealed chassis. Unlike standard vacuums, every H-Class unit is individually tested and certified to ensure no hazardous fibres can bypass the filter or leak through the casing.
Why Are H-Class Vacuums Important?
When dealing with "High-Hazard" materials, the margin for error is zero. Using H-Class equipment is a mandatory requirement for specialized sectors:
- Maximum Health Protection: H-Class vacuums are designed to trap microscopic particles like asbestos fibres and lead dust, which can cause terminal illnesses such as mesothelioma, lung cancer, and systemic poisoning.
- Legal Compliance (COSHH & HSE): In the UK, the Health and Safety Executive (HSE) and COSHH regulations mandate H-Class extraction for any material with a Workplace Exposure Limit (WEL) of less than 0.1 mg/m³. Failure to use certified equipment can lead to massive fines, site closures, and legal prosecution.
- Strict Containment & Disposal: H-Class vacuums feature "low-dust" or "dust-free" bag change systems. This ensures that when the vacuum is full, workers are not exposed to a "dust cloud" during disposal—a common failure point in lesser machines.
- Acoustic & Visual Safety Alarms: To comply with BS EN 60335-2-69, these machines include integrated sensors that trigger an audible alarm if the airflow drops below 20m/s, alerting the operator to a blockage or filter saturation immediately.
Materials Requiring H-Class Collection
H-Class vacuums are required for dusts contaminated with carcinogens, pathogens, or toxic substances where the exposure limit is extremely low.
| Material Type | Common Sources & Hazards |
| Asbestos | Licensed and non-licensed removal of lagging, floor tiles, and textured coatings. |
| Lead Dust | Stripping lead-based paints, renovation of heritage buildings, or firing range maintenance. |
| Silica (RCS) | High-intensity grinding or cutting of stone and concrete (where H-Class provides a higher safety margin than M-Class). |
| Carcinogenic Dusts | Processing of materials containing bitumen, tar, nickel, cobalt, copper, or cadmium. |
| Pathogenic Hazards | Mould spores, bacteria, germs, and pharmaceutical waste in lab or clinical settings. |
| Highly Toxic Finishes | Sanding of certain chemical-heavy coatings, resins, and formaldehyde-based materials. |
⚠️ Important Safety Note: H-Class Compliance
H-Class extraction is a life-safety requirement. Because exposure to toxic, carcinogenic, or pathogenic dusts (such as asbestos or respirable crystalline silica) can lead to fatal respiratory diseases, a formal COSHH Risk Assessment must be conducted to determine the correct filtration level for your specific materials.
Standard industrial vacuums are not sufficient for high-hazard environments. For official UK guidance on the selection and use of H-Class equipment, please refer to the HSE Usin a H-Class Vacuum Cleaner page.
