THE Safety Utility Engineering Ltd. CAFS 400 Gallons / 500 Gallons Compressed Air Foam Fire Suppression System uses compressed air to propel fire fighting foam. Thousands of tight radius bubbles quickly cool and smother a fire by providing a thick vapor-sealing blanket of foam that virtually eliminates re-ignition. The foam will adhere to horizontal and vertical surfaces. This system allows the operator to seal a fuel spill and flammable vapors with foam thus reducing or eliminating a potential fire. The system will discharge the foam approximately 25-30 meters. in a no wind condition allowing fire fighting personnel without protective clothing to avoid thermal injuries. Trained personnel can accomplish all maintenance except the hydrostatic pressure testing of the Air Cylinders, Premix Tank, and the Discharge Hose.
