Wet chemical extinguishers permanent pressure - Frost proof

Frost protected down to -30 °C

Economy line

The DÖKA permanent pressure water fire extinguishers are equipped with an extinguishing agent cylinder made of quality sheet steel. The high-quality outer polyester resin coating is tough and weatherproof and protects the extinguishing agent container from corrosion. Inside, the extinguishing agent container is protected from corrosion by a thermoplastic polymer inner coating. The metal fitting with pressed brass body is equipped with a pressure gauge and a separate test valve

ABF foam

The special foam compound, which is also suitable for fire classes A (flammable solids) and B (flammable liquids), forms a thick barrier layer on grease fires and thus prevents further oxygen supply, the flame is suffocated. At the same time, the extinguishing agent ensures that the fat cools down quickly and thus provides effective protection against re-ignition. The special foam agent is frost-resistant down to -30 ° C, which means that the DÖKA FBi6BS can also be used outdoors, e.g. in food trucks.
