Foam (AFFF or AR-AFFF) • Suitable for Class A and B fires (solids and flammable liquids) • Ideal for fuel stations, warehouses, and aviation facilities 3. CO₂ (Carbon Dioxide) • Effective on Class B (flammable liquids) and electrical fires • Commonly used in server rooms and electrical substations 4. Water or Water Mist • Works on Class A fires (wood, paper, textiles) • Used in warehouses and large storage facilities Key Features • High Capacity: Ranges from 25kg to 100kg (dry powder), 25L to 150L (foam), or large CO₂ cylinders • Trolley-Mounted: Easy to transport in large areas • Long Discharge Duration: Can operate for extended periods compared to handheld extinguishers • Hose and Nozzle System: Allows better reach and control
