2 Introduction
2.1 OVERVIEW
The CAFSAttack Air Bottle Compressed Air Foam Pumping System is
designed for installation on new or for retrofit onto existing fire apparatus.
The CAFSAttack system must be considered an additional option on a fire
fighting apparatus and must not impair the operation of the basic system.
The performance of the original fire fighting system, as well as personal
safety, must not be compromised.
CAFSAttack offers accurate push-button, compressed air foam from a
stored air supply using Class1 “Smart-Switch” electronic technology. The
Class1 Smart-Switch provides enhanced fire fighter safety, performance
and ease of use. Two 200 cfm capacity pressure “balancing regulator”
valves “balance” water and air pressures.
Dual compressed air foam discharges provide variable foam consistan-
cies. For example, one line can generate a “WET” quick draining foam blan-
ket; while the second line could discharge “DRY,” shaving cream-like foam
for exposure protection.
The CAFSAttack DOT high pressure compressed air bottle cylinders are in
compliance with NFPA 1989 “Standard on Breathing Air Quality for Fire and
Emergency Services Respiratory Protection” regulations.
The CAFSAttack system is shipped in modular assembly form, completely
tested and ready for installation on full size municipal, forestry and skid
units. (See Figure 2-1: “CAFSAttack System Overview,” on page 16.)
The CAFSAttack System includes the following modular assemblies:
❑ Dual DOT high pressure (4,500 PSI / 310 BAR) compressed air bottle
cylinders (H-cylinder type) having a capacity of over 440 cubic feet
of storage, fully assembled as a complete unit.
❑ Dual HIGH pressure (4,500 PSI / 310 BAR and 1,000 PSI / 69 BAR)
valve assembly
● The first high-to-low air pressure “balancing” regulator valve (4,500
PSI) is direct acting and dome loaded to provide constant discharge
pressure - 200 cfm capacity. The second valve (1,000 PSI) is also
direct acting and reduces pressure to 1,000 PSI for best overall
performance.
