Foam solution is available once the foam concentrate is added to the fire pump dis-
charge. Discharge valves, plumbed into the system, provide foam solution, not
CAFS. To obtain CAFS, air must be added to create compressed air foam.
The Compressor System is designed to deliver continuous duty performance.
Compressed air is added proportionally into the foam solution flow, controlled by
the CAFSPro controller. The CAFSPro monitors the air flow and provides a digital
readout on the control panel.
Mixers, downstream of the air injection point, assure proper foam mixing before dis-
charge. Compressed air foam is available through the compressed air foam dis-
charge valves on the apparatus.
The Air Compressor includes a closed-loop lubrication system that both lubricates
and cools the compressor. A water-to-oil heat exchanger is added to cool the air
compressor oil. An “optional” standby air to oil cooler is an additional option to
reduce the amount of heat transferred into the pump water in warm climates.
Compressed Air Foam produced by the Hale CAFSPro system varies in consis-
tency from WET to DRY by adjusting the CAFSPro control on the pump operator
panel. DRY foam contains more air than water. This can be valuable in exposure
protection, creating a thick long lasting foam blanket. WET foams generally have
approximately 0.5 to 1.0 SCFM of air for every GPM of water and are usually used
for direct attack.
WARNING !
A COMPRESSED AIR FOAM SYSTEM CAN BE A VALUABLE FIRE FIGHTING
TOOL. HOWEVER, PROPER OPERATION AND TACTICAL USE OF THIS
TOOL NEEDS TO BE ADDRESSED THROUGH TRAINING AND EDUCATION.
THIS MANUAL COVERS BASIC OPERATION OF THE HALE CAFSPRO SYS-
TEM. FURTHER EDUCATION AND TRAINING ON FOAM AND COMPRESSED
AIR FOAM IS REQUIRED FOR EFFECTIVE AND SAFE FIRE FIGHTING USE OF
THIS EQUIPMENT.
DRY FOAM IS NOT RECOMMENDED FOR STRUCTURAL FIRE SUPPRESSION
OR DIRECT FIRE ATTACK.
CAFS discharge hoses are handled differently than plain water hoses at the same
pressure.
❑ Lighter Hoses
Because a CAFS hose line is filled with almost half air in the form of foam
bubbles, a 1-3/4” (45 mm) hose line handles more like a 1” (25.4
mm) line. The hose line floats on water and is easier to advance.
