Clean air is a CSR :

Dilution Ventilation System :

» Inefficient -              Large volumes of air to be moved
» Coolant Loss -       No possibility of coolant recovery
» Costly -                  Substantial heat loss through doors windows & extractor fans
» Unhealthy -            Mist drawn or blown through workers breathing area

Exhaust Ventilation System :

» Least Power consumption -       Limited Air Volumes Exhausted by Axial Flow Fans
» Power savings -                         Lower Air Volumes / Reduced Air Washer Capacity
» Inefficient -                                 Large volumes of air to be moved
