The 50 kg wheeled dry powder extinguisher is used where larger agent capacity and longer discharge support are needed, such as factories, warehouses, fuel handling zones and logistics facilities.

• ABC dry powder is suitable for initial Class A, Class B and Class C fires.
• The unit should be operated by personnel familiar with wheeled extinguisher deployment.
• It is intended for initial response before a fire becomes large or unsafe to approach.

The unit consists of a trolley frame, cylinder, valve head, pressure indicator, hose, spray gun, extinguishing agent and driving gas. Opening the valve releases pressurized powder through the hose and spray gun.

• The cylinder and trolley frame provide mobility and large capacity.
• The spray gun allows controlled aiming at the fire base.
• The pressure system must not be altered or refilled without authorization.

Keep the extinguisher in a dry, visible, unobstructed location away from corrosive atmosphere, rain, direct sunlight and high temperature.

• Inspect wheels, axle, frame, hose, spray gun, pressure indicator and seal.
• Confirm that the hose can be removed and extended without obstruction.
• Keep maintenance records and service labels readable.

• Repair and recharge must be performed by authorized service personnel.
• Confirm zero internal pressure before valve or head removal.
• Inspect cylinder defects, valve damage, hose cracking, wheel damage and spray gun function.
• Hydrostatically test pressure-bearing parts where required.
• Replace seals, gaskets, damaged metal parts, pressure indicators and discharge components as needed.
• Use only approved ABC dry powder agent for recharge.
