High Expansion Air Foam Generator
1.High Foam Generation Efficiency: It can quickly produce a large amount of high-expansion foam (usually 200-1000 times expansion ratio), filling or covering the fire area in a short time with fast fire-extinguishing response speed.
2.Wide Fire-Extinguishing Coverage: The foam has large volume and strong fluidity, which can penetrate into narrow spaces (such as basements, equipment gaps) and is suitable for fighting large-area or hidden fires.
3.Strong Fire-Extinguishing Safety: The foam has low density and low water content, which can effectively block the contact between the fire source and air. It causes little secondary damage to equipment and the environment, especially suitable for scenarios with valuable facilities.
4.Flexible Application Scenarios: It can be used with fixed or mobile systems, and is applicable to various fire-risk places such as warehouses, oil depots, underground buildings and ships, with strong compatibility.
5.Easy Operation and Maintenance: With a simplified structural design, daily maintenance does not require complex procedures. Some models support quick assembly and disassembly, enabling convenient emergency deployment.
Product Introduction
PF(PFS)high expansion foam generator is one of the main equipment of high expansion foam fire extinguishing system and can be used on fixed fire extinguishing devices.It can also be used on mobile fire extinguishing equipment,characterized by high foaming capacity and suitable for extinguishing various types of fires.PF(PFS) series high expansion foam generator is a water pump that provides the pressure mixed solution to deliver to the generator.When the mixed solution passes through the water spray wheel,the rotating jacket drives the fan blade to rotate,thus form ing a secondary afterburner rotation,so that the fan can generate strong airflow,blow up the mixed solution to produce a large amount of high expansion foam to cover the fire point,which has the functions of cooling,oxygen isolation and fire extinguishing,and protecting personnel safety.
