The FKO Fire Knock Out has a special feature: it automatically starts to operate when it comes into contact with open fire and then fights the seat of a fire within a few seconds. The plastic container is filled with a harmless fire extinguishing fluid and activation (powder) material, on which a quick fuse is fitted.

As soon as the fuse comes into contact with open fire, the container splits open. During a short moment all oxygen in and around the seat of the fire is removed, as a result of which the fire is fought immediately.

The fire extinguishing fluid that has been atomised into water vapour cools down the heat source, while the added delaying substances reduce the chance that the seat of a fire will be ignited again to a minimum. All this only takes a few seconds. The plastic residuals that remain after use can be collected easily and can be fully recycled.

The FKO Fire Knock Out is supplied in various versions and models. The most common version is based on a foam basis and suitable for fighting class A fires (solids, usually of organic origin, in general with a glow development), class B fires (fluids or substances becoming fluid) and class C (gaseous) fires. Almost all versions can be used in closed areas and with outside fires.

The FKO Fire Knock Out products are supplied, among others, in a 1.6 and 5.6 packing (and a 24.6 packing for the specific professional market). The first two models are very suitable for mobile use because of their light weight and small size. The 5.6 version has a plastic handle, so that it can be carried easily by the professional user or hung somewhere as prevention.

The 1.6 and 24.6 packing is only for preventive use and must be placed at vulnerable places, where perhaps a fire could develop. When correctly applying the fire extinguishing liquid, the system has no restrictions. A suitable model is available for each type of fire. The packing is hermetically dust-proof and moisture-proof, so that the maintenance is limited to a periodical visual inspection.
