The purpose of the truck is to screen out any oversized material present in the firewater stream which in turn prevents nozzle blockages and equipment damage. The capacity of the truck with 4 x 300 NB In-line Guard Screens is 40 000 l/min. The equipment is unique in the way that no flow restriction is experienced during operation and automatic flushing of the unwanted material occurs during operation.
