Air filtration system
ARTICLE
Hanson Aggregates’ Craig yr Hesg quarry near Pontypridd in South Wales is a gritstone deposit with a silica content of 70 per cent. All the mobile plant is fitted with air filtration systems to protect drivers from respirable crystalline silica dust, which offer adequate protection, but there is no way of telling when the filters need replacing.

Eastfield Engineering from Wolverhampton was commissioned to design and install new High Efficiency Particulate Arrestor external air filtration systems to the cabs of two dump trucks and a loading shovel. Crucially, they incorporate a cab warning light which tells the operator when the filter needs replacing.
