Richardson Apparatus


The CET CAFS provides a self-contained, gasoline-powered, “slide-in” type compressed air foam system (CAFS) unit. The CAFS unit is designed to fit into the back of a standard length and width pick-up truck body, to discharge water only, air only or compressed air foam from the same discharge outlet. In addition, the consistency of the compressed air foam (expansion ratio), wet/dry is fully adjustable.



  1. Class A foam allow faster fire suppression and extinguishment than plain water
  2. Foam clings to most surfaces and protects exposures much longer than plain water
  3. Class A foam may provide long-term cost savings and may reduce property damage
  4. Class A foam increases efficiency and conservation of water supply
  5. Class A foam can be produced at a relatively low cost
  6. Class A foam forms a protective blanket
  7. Foam is visible during and after application
  8. CAFS attack lines are lighter than plain water hose lines
  9. Foam use may help to preserve evidence of fire cause
  10. Class A foam aids wildland/urban interface attack
