We offer an extensive range of dust extractor unit sizes from 17 litres – 48 litres and types from small portable extractors for general dust extraction and cleaning, to specialised concrete and plaster dust extractors, to compressed air service units. These extractors are designed to optimise your work, and your health, by efficiently removing dust.
Dust Types and Classes
L Class (low risk) dust includes simple house dust and materials such as soil. The occupational exposure limit for L Class dust is >1 mg/m3, which means you need a dust extractor that catches 99% of the dust.
M Class (medium risk) dust includes wood dust, dust from repair compound, filler and clear coats, dust from cement, concrete and tile cement, quartziferous materials such as sand and pebbles, and even paints such as latex and oil paints. The occupational exposure limit for M Class dust is >0.1 mg/m3, which means you need a dust extractor that catches 99.9% of the dust.
H Class (high risk) dust includes dust containing carcinogenic or pathogenic particles as well as mould spores, asbestos, mineral fibres, bitumen and artificial mineral fibres such as glass wool. The occupational exposure limit for H Class dust is >0.1 mg/m3, which means you need a dust extractor that catches 99.995% of the dust.
We are in the process of setting up service and repair centre for H Class Dust extractors. This facility will be launched in Christchurch in mid January 2020.
