Numatic HZ900 Professional H-Class Vacuum Cleaner
The Numatic HZ900 is a heavy-duty professional hazardous-dust vacuum developed for environments where potentially harmful dust and materials must be collected and controlled effectively.
Part of Numatic's professional ProCare hazardous-dust range, the HZ900 combines a substantial 40 litre drum with advanced filtration, robust construction and professional cleaning performance.
The machine complies with H-Class requirements under IEC/EN 60335-2-69, making it suitable for appropriate applications involving high-risk, non-explosive hazardous dust when used in accordance with applicable regulations and safe working procedures.
H-Class Hazardous Dust Filtration
Hazardous dust requires considerably greater filtration and containment than conventional commercial vacuum cleaning.
The HZ900 uses a multi-stage filtration arrangement incorporating HEPA H13 filtration, TriTex filtration and high-efficiency HepaFlo dust bags.
Numatic's H-Class range is designed specifically for controlling hazardous and health-endangering dust, with the filtration system helping ensure collected material remains contained within the machine.
Large 40 Litre Capacity
One of the principal advantages of the HZ900 is its 40 litre drum capacity.
This makes the machine particularly attractive for larger-scale applications where the smaller capacities of compact H-Class vacuums would require more frequent interruption and emptying.
Despite its substantial capacity, Numatic equips the machine with large rear wheels and a robust chassis to improve movement around demanding working environments.
Powerful Professional Performance
The current Numatic 2026 catalogue specifies the HZ900 with a professional 960W motor, delivering up to 2500mm H₂O suction.
A 10 metre power cable combined with the hose and accessory system provides an overall cleaning range of approximately 26.8 metres, allowing large working areas to be covered efficiently.
Robust Construction for Demanding Environments
The HZ900 has been designed as a professional rather than domestic vacuum.
Its heavy-duty construction includes an all-steel powerhead, robust drum, large rear wheels and professional accessory system. Numatic specifically highlights the 900-series construction for demanding hazardous-dust applications where machine capacity, durability and filtration are important considerations.
Easy, Clean & Controlled Emptying
Containment remains important after hazardous material has been collected.
The HZ900 is designed around high-efficiency dust bags and a filtration arrangement intended to facilitate cleaner, controlled emptying while reducing unnecessary operator contact with collected material.
Correct procedures, appropriate PPE and applicable regulations must still be followed whenever hazardous dust is handled or the vacuum is emptied or maintained.

*Numatic's current 2026 catalogue specifies 960W; a recent HZ/HZD instruction document lists the HZ900 at 1000W, so I would use the specification on the exact machine/SKU you're currently supplied with before publishing the motor figure.
Ideal Applications
The HZ900 is particularly suited to professional environments requiring controlled collection of hazardous dust, including construction, specialist contracting, industrial maintenance, facilities management and other appropriately assessed hazardous-dust applications.
For high-risk materials such as asbestos, Numatic states that H-Class equipment is required, but machine selection is only one part of the control system. Applicable HSE requirements, specialist procedures, PPE, training and risk assessments must also be followed.
FAQs
What is the Numatic HZ900?
The Numatic HZ900 is a large-capacity H-Class professional hazardous-dust vacuum cleaner designed for collecting high-risk non-explosive hazardous dust and materials.
