PF‑4 High‑Expansion Foam Generator

Name: China PF‑4 High‑Expansion Foam Generator Manufacturers Suppliers Factory - CA-Fire Protection
Brand: CA-FIRE
SKU: 299045590

The PF‑4 high‑expansion foam generator is a core component of modern high‑expansion foam fire extinguishing systems, designed for both fixed installation and mobile firefighting applications. Engineered for high output and stable performance, it delivers large‑volume foam to rapidly flood and cover burning surfaces, achieving cooling, smothering and suffocating effects to effectively extinguish various types of fires. With a compact structure and reliable operation, it is widely used in confined spaces, warehouses, workshops, hangars, petrochemical sites and other high‑risk fire zones.

Product Overview

PF‑4 High‑Expansion Foam Generator

This generator adopts a hydraulic drive design that requires no external power supply. When water and foam mixture enters the device, it drives the water turbine to rotate the fan, while the nozzle sprays the premixed solution onto the foam net. Strong airflow generated by the fan turns the liquid into massive high‑expansion foam, which quickly covers the protected area to suppress flame spread and prevent re‑ignition. The whole process is stable, efficient and highly responsive, making it ideal for large‑space and deep‑seated fires.

Made of durable, corrosion‑resistant materials, the PF‑4 features a sturdy casing, high‑strength foam net, reliable hydraulic motor and well‑balanced impeller. It supports a wide working pressure range of 0.3–1.0 MPa, with a rated inlet pressure of 0.6 MPa and rated mixture flow of 4 L/s. The expansion ratio reaches above 200 times, and the 50% drainage time is no less than 5 minutes, ensuring long‑lasting foam coverage and strong extinguishing durability.

Industrial Installation

Installation is simple and standardized: the air inlet must be kept clear of obstacles within 3 meters, and no barriers are allowed within 1 meter in front of the foam net. For full‑flooding systems, the generator should be mounted higher than the designed foam level, with the foam net facing the protection zone. Such layout ensures smooth foam output and full coverage.

Routine maintenance includes regular cleaning of the foam net to remove dust and debris. After each use, the unit must be flushed with clean water to avoid residue buildup. An annual inspection is required, including a 1.25 MPa hydrostatic test to verify sealing performance and structural integrity. No disassembly is allowed during daily use to maintain consistent performance.

FAQ

What types of fires is the PF‑4 suitable for?It is mainly used for Class A fires involving solid materials and Class B fires involving flammable liquids, especially in large enclosed or semi‑enclosed spaces.

Does the generator need electricity to run?No. It is driven hydraulically by the incoming water flow, so no power or battery is required.

What is the foam expansion ratio?The expansion ratio is ≥200, producing a large volume of light foam to flood the fire area quickly.

How to install the generator correctly?Keep 3 m clear space at the air inlet and 1 m unobstructed space in front of the foam net. Install it higher than the designed foam level for full‑flooding applications.

What maintenance is required?Clean the foam net regularly, flush the unit with clean water after use, and perform a 1.25 MPa hydrostatic test once a year.

What are the key working parameters?Rated inlet pressure: 0.6 MPa; working pressure: 0.3–1.0 MPa; rated flow: 4 L/s; 50% drainage time: ≥5 min.
