fire fighting equipment

Portable stored-pressure powder series extinguishers are effective extinguishing appliances,in which extinguishing gaent sodium bicarbonate and ammonium phosphate powder together with the driveng gas -nitrogen are filled in a full-sealed container.During application ,nitrogen drives to jetting powder forfire fighting equipment ,which is fast and effective in extinguishing,light in weight ,convenient and simple in operation,safe and reliable. model specification MFZ /ABC1 MFZ /ABC2 MFZ /ABC3 MFZ /ABC4 MFZ /ABC5 MFZ /ABC8 1 Extinguisher classification 1A21B 1A21B 2A34B 2A55B 3A89B 4A144B 2 Weight of extinguisher agent (kg) 1±0.05 2±0.06 3±0.09 4±0.08 5±0.10 8±0.16 3 Nitrogen pressure (Mpa20 ±5) 1.20 0.12 1.20 0.12 1.20 0.12 1.20 0.12 1.20 0.12 1.20 0.12 4 Effective spray time (s) 8 8 13 13 13 15 5 Spary residual rate (%) ≤15 ≤15 ≤15 ≤15 ≤15 ≤15 6 Delayed-action time of discharge(s) ≤5 ≤5 ≤5 ≤5 ≤5 ≤5 7 Effective spray distance (m) 3.0 3.0 3.5 3.5 3.5 4.5 8 Application temperature () -20 +55 -20 +55 -20 +55 -20 +55 -20 +55 -20 +55
