SENTRY: K-GUARD™ Extinguishers contain PRX™ Liquid Fire Suppressant, a specially formulated, aqueous solution of inorganic salts. In addition to knocking down the flame and forming a vapor-securing blanket, PRX agent provides a cooling effect that aids in the extinguishing and securing process. For these reasons, Ansul uses this same liquid agent in both our K-GUARD™ extinguishers and our PIRANHA ™ restaurant fire suppression systems. The K-GUARD ™ extinguisher is equipped with a special wand/nozzle combination. The extension wand allows the operator to stand back from the fire area and still accurately direct the flow of agent to the fire. The nozzle applies the agent in a fine spray to prevent unwanted splashing of the burning grease. The K-Guard has a discharge time of 40 - 45 seconds and have an effective discharge range of 10 - 12 ft. The K-Guard stands 19" tall and attaches to the wall with a standard wall hook.
