Foam fire extinguishers are the ideal choice for Class A and B fire risk areas (those featuring combustible materials and flammable liquids). That makes them perfect for spaces like offices, warehouses, shops, factories and garages. The knockdown (compared with that of a water unit) means they’re an excellent choice.

This six-litre unit from CommanderEDGE boasts a new and improved 21A 183B fire rating, is Kitemarked and 35kVa dielectric test certified. Plus its sturdy base and CE-marked brass valve assembly mean it’s a high performer even in the harshest of surroundings.
