Fire fighting tanker AZ-5,0-50 (4320) with CAFS
Description and technical characteristics
Firefighting pumped-tanker AZ-5,0-50 on chassis Ural-4320-79 is designed to deliver firefighting crew with a water–supply, foam agent and the fire–technical equipment to the place of fire origin. Fire extinguishing by water from the tank, reservoirs and hydrants, and by air – mechanic foam are available. The vehicle is equipped with pump unit LSA3000 which may be used both as standard fire pump and effective compressed foam firefighting system.

Pump unit LSA 3000
Usage:
- water supply (including seawater);
- foam agent supply;
- «wet» compressed foam supply;
- «dry» compressed foam supply.
CAFS (Compressed Air Foam System) advantages:
- increase of the firefighting and rescue potential of the firefighting vehicles;
- reduction of fire extinguishing time (max. effect of CAFS is achieved on the first stage of operation);
- reduction of the harmful environmental impact;
- increase of the vehicle operation without refilling by reduction of the foam and foam agent volume;
- possibility of the simultaneous operation from one fire pump both with water supply nozzles and foam nozzles;
- possibility of compressed foam supply when working at high buildings;
- economy of foam agent by usage of the more concentrated (1%) foam agents and exacting electronic inspection of the foam agent consumption.
LSA 3000 assembly:
The pump unit LSA 3000 consists of the following elements based on the frame in united module:
- noncorrodible firefighting centrifugal pump of a normal pressure Johstadt NP 3000;
- priming system;
- pump for foam agent supply;
- compressor;
- automatic electronic injector system of compressed air and foam dosing;
- ejector system of foam agent supply and dosing with manual operation (optional);
- pipe lines and locking devices;
- control panel with illumination.
