At what differential pressure must the receiving strainer in the Type 3 system be cleaned?

The receiving strainer in the Type 3 system should be cleaned at a differential pressure of 10 pounds per square inch (psi) to ensure optimal performance and prevent any potential issues related to clogging or reduced flow. This specific pressure threshold is based on operational parameters designed to maintain system efficiency and protect downstream components from debris and contaminants that may accumulate in the strainer.

Cleaning the strainer at this differential pressure helps to balance the need for filtration with the effectiveness of the strainer’s function in the system. Ignoring this maintenance requirement or performing it at the wrong pressure could affect fuel or water flow, leading to degraded system performance or even failure in more extreme cases. Thus, the 10 psi mark is critical for reliable operation and maintenance protocols in the Type 3 system.
