What is a limitation of using a foam nozzle eductor?

Foam nozzle eductors rely on suction to pull foam concentrate into the water stream, so keeping the concentrate within the eductor’s pickup path is essential for continuous foaming. When you move the nozzle, you must move the concentrate as well to maintain that suction and the proper mixture ratio. If the concentrate isn’t relocated with the nozzle, the eductor can lose prime, and foam production can drop or stop altogether. This is a practical limitation of this type of system: the foam supply isn’t fixed in place at the nozzle, so coordination is needed between moving the nozzle and the concentrate source. The other statements misstate how these systems are used or their compatibility, so they don’t capture the reason this limitation exists.
