This large size cylinder pack is suitable for missions requiring extended duration time. The cylinder pack consist of two cylinders mounted together with a pipe protected inside the handle and is equipped with one cylinder valve. The design with two cylinders has the following advantages:

• Possible to move more freely, for example lying on your back when spraying water at the roof
• Easier to drag out a fire fighter in an emergency
• Easier handling between mission since it cannot roll and is easy to place upright

The cylinder valve has a pressure gauge, burst disc and safety ratchet to prevent unintentional closing. 

The cylinder pack can be equipped with an optional Cylinder Quick Coupling.
