Numatic HZD900 H-Class Twin Motor Industrial Hazardous Dust Extractor
When managing high-volume, high-risk, or carcinogenic dust in industrial environments, power must be matched by absolute safety. The Numatic HZD900 H-Class Vacuum Cleaner is a heavy-duty, twin-motor powerhouse specifically engineered and certified to meet the most stringent global safety standards (IEC/EN 60335-2-69). It ensures the containment and safe disposal of large quantities of hazardous material in the toughest site conditions.
Available in 240Volt and 110Volt. Please select your preferred operating voltage.
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.
