6ltr Water Mist Fire Extinguisher - Act Fire

Traditional metal water mist fire extinguishers need to be serviced annually by a qualified engineer in the same way that foam, powder, and water extinguishers are. P50 Service-Free Water Mist Extinguishers do not require annual servicing by a technician.

Yes, de-ionised water mist fire extinguishers have passed the di-electrical conductivity test, which marks them as safe for use on live electrical equipment up to 1000v in accordance with BS EN3-7. Two key factors differentiate water mist fire extinguishers from traditional water or foam units: 

• Water mist extinguishers are filled with de-ionised water, which cannot carry electrical current.
• The microscopic droplets that form the signature mist are too small and too far apart for electricity to flow through them.

No, water mist extinguishers are probably the most environmentally-friendly extinguishers on the market. Our water mist extinguishers contain only de-ionised water – there are no chemicals in the extinguishers. This makes the discharge environmentally friendly and any spill or residue can be easily cleaned up.

Traditional water extinguishers deliver a jet of water which penetrates the surface of the burning fat, sinks because it is heavier than fat, and almost instantly evaporates. This rapid expansion pushes the burning fat out of the pan or deep fat fryer, creating violent flares and spreading the fire. With a water mist extinguisher; most of the droplets evaporate above the fat creating a cooling ‘blanket’ reducing the oxygen from the surface and preventing re-ignition. That is why our water mist extinguishers are suited to fight small F-Class fires such as on shallow frying pans and domestic deep fat fryers (typically 2 to 3 litres). On larger fat and cooking oil fires, such as commercial deep fat fryers, there is a larger surface area burning and a much larger volume of oil to cool, which may still be disturbed by the instant evaporation of the water mist droplets; for this reason, we recommend a wet chemical extinguisher for fires above a 5F rating.
