TEMPORARY VENTILATION

Civil engineering work within tunnels frequently generates fumes and respirable dusts of higher levels. Without some form of ventilation and monitoring, workers within tunnels can be exposed to dangerous levels of contaminants. These atmospheric hazards can be generated from a number of sources including engine exhaust gases, welding or cutting processes and the dust from handling of ballast stone.

WITT INDIA is providing solution to handle this with customized Ventilation Fans and complete system. With a wide range of blade designed and state of art manufacturing facilities WITT Fans deliver high performance with low power consumption.
