Permanent pressure SN-Series

Full metal valve with manometer

Economy line

The DÖKA permanent pressure powder fire extinguishers are equipped with an extinguishing agent container made of quality sheet steel. The high-quality polyester resin coating is tough and weatherproof and protects the extinguishing agent container from corrosion. The metal fitting with pressed brass body is equipped with a pressure gauge and a separate test valve as standard.

Extinguishing agent: Fluorine-free foam

The fire extinguishing agent foam is created from a water / foam agent mixture by adding air. In the case of fires involving solid substances (fire class A), the high network effect combined with the interruption of the gas exchange and the cooling effect result in the excellent extinguishing properties.

Foam extinguishing agents work by covering the entire surface of flammable liquids with a vapor-tight foam blanket, which prevents the entry of oxygen (sticking effect) and cools the surface (cooling effect).
