Brass valve and safety device for the highest demands on quality and safety

The DÖKA cartridge operated fire extinguishers of the BS series are equipped with a high-quality push button valve and cap nut made of nickel-plated brass. In addition to the standard, the BS series is also equipped with an additional pressure relief valve with a brass body, which protects the cylinder from excess pressure. The generous dimensioning of the safety device and strike button enables the fire extinguisher to be operated with gloves. The ergonomic handle with finger recesses and slip protection offers excellent carrying comfort. The rotating extinguishing pistol enables optimal control of the extinguishing agent jet and the operation of the fire extinguisher with just one hand.

The DÖKA BS series is the highest quality equipment variant of our rechargeable fire extinguishers. High-quality materials, the ergonomic design and the extensive selection of different types of fire extinguishers. We offer frost-proof wet and grease fire extinguishing agents as well as special extinguishing devices exclusively in the BS series. The PREMIUM LINE for the highest demands on quality, reliability and safety.

The DÖKA cartridge operated wet chemical fire extinguishers of the BS-series with internal propellant cartridge. The fire extinguisher is only put under operating pressure after pulling the securing and depressing the push button when it is in use. This ensures a high level of operational reliability, saves material and minimizes maintenance costs.

Extinguishing agent

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.

Quality features

Push button valve made of brass - only in the BS series

The body of the push button valve is made of nickel-plated brass. All other components such as hose, riser pipe, blow pipe and propellant gas cartridge are mounted on the base body. Nickel-plated brass is significantly more resistant to extinguishing media and environmental influences and therefore more durable than plastic fittings. For this reason we only offer certain device versions in the BS series, such as frost-proof water and foam extinguishers. We also offer fire extinguishers with MED approval, i.e. for use on ships, only in the BS series.
