2 How the CAFSPro System Works
A normal Compressed Air Foam System (CAFS) combines the fire-fighting proper-
ties of water and foam concentrate along with the power of compressed air. (See
Figure 2-1: ‘Normal Compressed Air Foam System.’)

The Hale CAFSPro ® system controls the combination of three components, water,
foam concentrate and compressed air – to make compressed air foam. (See Fig-
ure 2-2: ‘Hale CAFSPro Compressed Air Foam System,’ on page 14.) The CAF-
SPro system injects foam concentrate into the water discharge stream using the
Hale FoamLogix Foam Proportioning System. Air is then supplied by the Air Com-
pressor System. The CAFSPro system monitors the water flow rate and foam con-
centrate injection. The CAFSPro system only allows air injection if water is flowing
and foam concentrate is being injected by the FoamLogix into the water stream.
