WARNING
4.3 FOAM COMPATIBILITY
Do not mix different types of foam concentrates or foams of the same type from different manufacturers.
Mixing of foam concentrates can cause the contents of the foam tank to gel and produce unpredictable
Medium Expansion Nozzle
— produces the greatest expansion ratios. It should be used on Class B fuels for vapor suppression and
Class A fuels when a longer lasting insulating layer of drier foam is desired.
Low Expansion Nozzle
— can be used with either Class A or B foam solutions. Reach is slightly less than the smooth bore. It should be
used on Class B fires for extinguishment and Class A fuels to soak the fuel with a wet foam solution.
Straight Stream Nozzle
— is for Class A foam solutions. Foam expansion will be negligible. It should be used where maximum reach
or penetration is desired.

Low Expansion
Reach: 37 ft @ 100 psi
11 m @ 6.8 bar
Reach: 50 ft @ 100 psi
15 m @ 6.8 bar
Medium Expansion
Reach: 9 ft @ 100 psi
3 m @ 6.8 bar
Piercing Nozzle
— is for use with Class A foam solutions in deep-seated fires. Foam expansion will be negligible. It can be used where
an application of solution is needed but the location is inaccessible. The piercing nozzle is not designed to pierce metal and other hard
objects. To use behind hard surfaces, punch a hole first.
