Model D4A Nozzles

Like other Protectospray nozzles, the D4A is open, non-automatic, and releases a cone of medium-velocity water droplets. But unlike other Protectospray nozzles, the D4A features a four-arm body design that helps protect the unit from mechanical or physical damage. This unit releases a cooling spray to prevent excessive heat absorption, possible structural damage, or the spread of fire to protected equipment. In some applications, the D4A nozzles may also be used for fire control or extinguishment.
