MANIFOLD
The manifold incorporates an ARC Valve [air ratio control valve] through which degrees of wet or dry
foam mixture can be selected. Compressed air is then injected and the resulting foam / water / air
combination is thoroughly mixed by the X-mixers during discharge.
For salt water compatible foams or a specific solution’s effectiveness while using salt water, seek advice
from the foam agent manufacturers.
FOAM UNIT - FOAM PROPORTIONING SYSTEM
The Foam unit system consists of three main components:
1) Foam Pump / Motor Assembly.
2) Control Panel (integral with main pump control panel).
3) Flow measurement and injection manifold.
All three elements combine to provide accurate foam proportioning. From the control panel the
operator can initiate the system, adjust the foam ratio, monitor ‘real time’ water flow rate and record
total water and foam concentrate usage.
Foam concentrate is only injected when the foam button has the RED selector around the control
button.

The Foam unit 3.3, 5.0, 6.5 system for Class A or B foams, will inject foam in the range of 0.1% to
10.0%.
Further information is available in the Foam unit Model 3.3/5.0/6.5 Description, Installation and
Operation manual.
