Compressed Air Foam Systems (CAFS)

Compressed Air Foam Systems (CAFS) are a method of enhancing the fire fighting effectiveness of water. CAFS do this by injecting pressurized air and foam concentrate into the water stream generated by a fire pump. Very little foam concentrate is required to form the bubbles with this method as opposed to other methods, which use far more foam concentrate. CAFS foam expands water to between five and fifteen times it's original volume (example: one gallon of water truns into five to fifteen gallons of foam).

Advantages of Compressed Air Foam Systems

–Class “A” compressed air foam does an excellent job of protecting structures and wild lands.

–There is less smoke emitted when using Class “A” compressed air foam to suppress fires.

–Compressed air foam reduces structural water damage because much less water is used to
knock down a fire.

–Using compressed air foam will result in less water pollution than traditional fire fighting
methods.

–Applying compressed air foam is the lowest cost method of knocking down
fires and protecting structures, forests or wild lands.

–Compressed Air Foam will cling to all surfaces and can provide protection for up to 40 minutes and the gels can protect up to 20 hours.

Residential Fire Protection

Castle Defense began as a  dream about 8 years ago, to market a fire fighting foam system for the exterior of residences that are located on the urban interface. We began a search in early 2008 to locate a system worthy of marketing to home owners and located a company out of Canada. This company produces the FL Series, that is a frameless Compressed Air Foam System (CAFS) that is lightweight, simple to operate, and can be customized to the needs for the home owner.

These CAFS systems are similar to what some fire engines are equipped with. The Class A foam is non-toxic and non-corrosive. The foam produced using a CAFS system is more dense than aspirated foam units. This enables the unit to fill the hose with a dense foam rather than heavy, water which makes it easier to maneuver the hose in any situation. It only takes a matter of minutes to spray down a defensible barrier of foam on an average home and the foam will remain on the structure for up to 40 minutes depending on the environment. This foam clings to all surfaces, including under eaves and on walls, and creates a simple solution for protecting the entire structure against an approaching wild land fire. We also offer a gel unit sprays on a gel that will protect for up to 22 hours.

    Castle Defense is now able to offer the FL Series CAFS to the residential market in an effort to offer the home owner the most superior alternative to having a fire engine parked outside their home.
