What is an air foam generator?

An air foam generator is aFire protection equipment permanently installed on flammable liquid storage tanksThe core function is to mix foam liquid with air in proportion, generating a large amount of air foam that is then喷射 into the storage tank, covering the burning liquid surface to isolate oxygen, and achieving rapid fire extinguishing. It is a crucial fire protection device for storage facilities of flammable and explosive liquids, such as petrochemical plants, oil depots, refineries, and other similar sites.

1. Working PrincipleUpon activation of the fire suppression system, the foam mixture (a solution of foam liquid and water) is transported through pipes to the generator, where it passes through nozzles within to form jets. These jets draw in a large volume of air and mix it vigorously, ultimately creating a uniform and fine air foam. These foams are characterized by their low density, good fluidity, and strong coverage. They can quickly cover the surface of the flammable liquid inside storage tanks, blocking the oxygen required for combustion and simultaneously cooling the liquid surface, thereby achieving the effects of extinguishing fires and preventing re-ignition.
2. Core Categories and Applicable Scenarios

• Horizontal Air Foam GeneratorMostly installed on the upper part of the storage tank walls, the foam jet direction is parallel to the tank wall, suitable for auxiliary fire extinguishing in horizontal storage tanks or large vertical storage tanks, with convenient installation and maintenance.
• Vertical Air Foam GeneratorFoam weir plates, typically installed at the top of storage tanks, evenly cover the liquid surface with a vertical foam jet that spreads along the weir plate, providing a more uniform fire extinguishing coverage for all types of vertical fixed-roof storage tanks.

1. Key Features

• High fire extinguishing efficiencyCan rapidly produce a large amount of foam, covering the burning area in a short time, and controlling the spread of the fire.
• Adaptability is key.This product can be used in conjunction with various types of foam liquids (such as protein foam and synthetic foam) to meet the fire extinguishing needs for different flammable liquids.
• Installed securelyThis fixed fire protection equipment is specifically designed for storage tanks and must be installed in conjunction with the storage tank fire protection system to ensure quick and automatic activation in the event of a fire.

1. Cautionary InstructionsRegular inspections of pipeline通畅ness and sealing performance are necessary to avoid blockages and leaks affecting the foam generation effectiveness; at the same time, select the appropriate foam liquid based on the type of liquid stored in the tank to ensure compatibility with the burning material.
