What is the recommended pump pressure for testing a compressed-air foam system?

The recommended pump pressure for testing a compressed-air foam system is 125 psi. This pressure is specified to ensure that the system operates effectively while maintaining optimal performance and foam generation. Testing at this pressure allows for an adequate flow of foam concentrate and ensures that the foam can reach the necessary consistency and effectiveness for firefighting scenarios.

Using the specified pressure also aligns with the operational parameters of most compressed-air foam systems, ensuring that the equipment is functioning within its designed specifications. Operating at 125 psi helps emulate real-world conditions while still being safe and effective for testing purposes. This consistent standard is important for maintaining equipment and preparing for emergencies where foam application might be necessary.
