Mobile and Fixed Pant Cabins / Equipment are subjected to "Dusty" Contaminated Operating Environments in such industries as Mining, Quarrying, Construction, Earthmoving, Fertiliser, Cement, Agriculture, Timber and many others.
These environments contain Airborne Particulate / Fibres that can cause severe lung disease and other short and long term health issues. Subsequently, Airboren Particulate / Fibre must be removed before entering (External Air Supply)- and removed immediately if entrapped (Recirculation Air) when ingress occurs into the Operator's Cabin.
These are a few video clips of example operating environments.
