ABC Dry Powder Fire Extinguisher: How to Choose Capacity (1kg–50kg)

2026-09-20 09:00:00

Choosing the right extinguisher capacity is the first step in any fire-safety tender or retail programme. ABC dry powder (monoammonium phosphate) covers Class A, B, C and live electrical fires, making it the most versatile agent for distributors across Southeast Asia, the Middle East and the Belt & Road markets.

1kg–8kg portable units

Compact 1kg–4kg units suit cars, homes, shops and small offices where space is limited. The 4kg–8kg units are the workhorses for commercial buildings, workshops and factories, balancing capacity with manageable weight. Pressure is typically 14 bar with a discharge range of 3–6 m.

20kg / 35kg / 50kg wheeled units

Above 8kg, a trolley (wheeled) design becomes necessary. Wheeled 20kg/35kg/50kg extinguishers deliver large powder charges with 6–10 m hoses and horns, ideal for warehouses, oil depots, ports, chemical plants and factories where rapid, high-volume response matters.

How buyers decide

Match capacity to the fire load and the site. A distributor serving mixed retail and project tenders usually stocks 2kg/4kg/6kg/8kg portable plus 20kg/35kg wheeled. We provide complete FOB quotations and OEM branding so buyers can build a full range from one supplier.

Sichuan Longshengan Fire Equipment Co., Ltd. supplies 1kg–50kg ABC dry powder extinguishers and OEM components with ISO 9001/14001/45001 and CE/EN3 where applicable. Contact us for FOB quotes and catalogue.
