CAFS provides quicker knockdown, deeper penetration of fuels, and the advantage of making an initial attack from a significantly greater distance than with a water stream or fog pattern.  The tiny bubble structure allows for a greater expansion of the waters surface area, allowing for greater heat reduction compared to equal amounts of plain water.  Some studies have indicated that CAFS increases the effectiveness of water by approximately  five times.  Foam blankets allow for pre-treatment of fuels that are not already involved, and have less adverse impact on property, and evidence used in investigations.

The process is relatively simple.  The addition of a foaming surfactant to water breaks down the surface tension of water droplets allowing for fuel penetration.  Then the introduction of compressed air into the foam solution produces foam, the expansion of which increases the surface area of water.  The ratio of air to foam solution determines the viscosity of the foam. 

This brings us to the "Equalizer"®.  The design of the "Equalizer"® is such that the air and solution water are introduced into the same chamber at the same time.  They meet in such a way that a violent turbulence causes foam to be generated that has a smaller bubble structure, better consistency, and greater trajectory than other foam systems on the market.  Pressures are balanced inside the "Equalizer"® thanks to the laws of physics.   The ability of the "Equalizer"® to produce great foam is not limited by higher water pressures.  Other foam systems are limited to around 100 to 120 PSI water pressure.  The "Equalizer"® can operate at pressures exceeding 180 PSI.  It does not require any adjustments, pre-balancing of pressures, tweaking, or guesswork.  Three years of extensive R&D went into the design of the "Equalizer"®.  A design so unique, that it is patented.*
