seen here is the Japanese Isuzu NPR lighting&ventilation truck. It is a 2 in 1 truck. It can be a lighting truck and also a ventilation truck at the same time.
Is sucking the smoke out better than positive pressure ventilation? It seems to be a lot of machine for a task which can be performed by a simple fan unit.
the diffrents of neg and pos venting is great... you have to learn about ventilation... we use both positive in the front and negative ventilation in the back it works very fast at clearing a room of smoke and heat.Tim USA Firefighter
