Dealing with Hazardous Dusts: A Guide to H-Class Vacuum Cleaners


Certain dusts are hazardous to health if inhaled. These include asbestos, carcinogens, finely divided silica, active pharmaceutical products and soot. In environments where these dusts are present and need to be cleared, it is necessary to use highly specialist equipment to do so.

H-class vacuum cleaners are purposely designed for use with hazardous dusts. They are built to safely and effectively pick up toxic dust and debris in a safe manner.

H-class vacuum cleaners are equipped with three stages of filtration. The first is a sealed, disposable paper bag. The second is a high efficiency cloth filter, and the third is a HEPA (High Efficiency Particulate Air) cartridge which is contained in a sturdy module. All hazardous dust vacuum cleaners are tested in line with British Standard BS5415 to ensure they achieve a filtration efficiency of at least 99.97 per cent.

Numatic manufactures a range of specialist hazardous dust vacuum cleaners in a variety of capacities up to 40 litres, and with a choice of Twinflo single 1200 Watt or double 2400 Watt motors built into an all-steel, low-noise power head. All models are available in both 240 volt and 110 volt options and feature a HEPA filter with a primary pre-filter and microflo dust bags to meet the required filtration efficiency.

The Numatic HZ200 and HZ250 are the smaller models in the range. These have a 10 litre steel container.

In the small to medium range, featuring a 15 litre polypropylene container, are the Numatic HZ350 and HZ370.

The Numatic HZD570 is a medium sized model offering a 23 litre super tough structofoam container. For higher capacity needs, the Numatic HZ750 single motor and HZD750 twin motor models offer a 35 litre steel container.




For even greater capacity, the Numatic HZ900 single motor and HZD900 twin motor feature a huge 40 litre super tough structofoam container.



All models come with an accessory kit including a 2.5 metre hose, small and large dusting brushes, a steel gulper, a crevice tool, 10 disposable paper bags and 20 polythene sacks.
