The Scotty 4000F 19L pump is a single action pump with a foam inducting attachment and air aspirating nozzle. This backpack eliminates the need to batch mix when Class A foam is required.

Each time the pump is charged, 1% of foam concentrate is inducted into the pump chamber. The air aspirating nozzle generates foam when the pump is discharged.

Manufactured from tarpaulin cloth the Scotty backpacks are more comfortable as they mould around the body which in turn means the cold water helps cool the firefighter. The large 19L capacity allows for maximum duration.
