❑ AIR TO FOAM SOLUTION
RATIO - The air-to-foam ratio
shows the consistency of the
compressed air finished-foam
that is being produced. For WET
foam, a range of 0.5 SCFM to 1
GPM is available. For the DRI-
EST foam, up to 11 SCFM is
available for every GPM (LPM).
This is adjustable using the WET
or DRY ARROW buttons. (See
Figure 4-3: ‘Hale CAFSPro Con-
trol Unit’ on page 33.).
❑ BAR GRAPH - between the wet
and dry arrows, also shows the
WET-to-DRY consistency of the CAFS stream. For WET foam, the bar
graph is darkest towards the left (WET button). For DRY foam, the entire
bar graph illuminates towards the right (DRY button).
Note: When air flow requirements exceed rated compressor capacity the fully
illuminated bar graph flashes.
WARNING !
DRY FOAM HAS VERY LITTLE WATER CONTENT AND IS GENERALLY SUIT-
ABLE FOR SINGLE LINE EXPOSURE PROTECTION ONLY.
❑ COMPRESSOR TEMPERATURE - The compressor temperature display
monitors the current temperature of the air compressor. (See Figure 4-4:
‘Sample, Display ICONS.’)
The air compressor is cooled by the water source inside the fire pump. It
is important that adequate fresh water be circulated around the pump to
cool both the fire pump and air compressor. If the compressor becomes
hot, a warning is displayed and the alarm buzzer sounds.
❑ TOTAL COMPRESSOR HOURS - The compressor run time display
shows the current amount of time that the compressor has been in use.
(See Figure 4-4: ‘Sample, Display ICONS.’)
4.4 WATER, FOAM SOLUTION, AND CAFS
Depending upon the plumbing of your CAFSPro system, it is possible to
flow plain water, foam solution, and compressed air foam from three differ-
ent hose lines simultaneously.
